Are Load Cells Used in Vacuum Environments?

Vacuum testing labs are essential for ensuring that products and materials are safe and dependable in vacuum environments. A vacuum environment is an area where there is little or no matter. This means that there are very few gas molecules present, and the pressure is incredibly low. Vacuum environments are often created using vacuum pumps, which remove gas molecules from an enclosed space.

Vacuum environments are used to simulate the conditions that products and materials will experience in space or other high-altitude environments. These types of testing labs typically have a vacuum chamber that can be evacuated to an incredibly low pressure. The vacuum chamber is then used to evaluate products and materials for a variety of properties. Engineers use vacuum environments in testing for reduced contamination, improving heat transfer, and to reduce the weight of products.

Tests performed in vacuum labs are used to determine the rate at which gases are released from a product or material and the ability of a product or material to withstand a vacuum without leaking. Thermal cycling tests are done to assess the ability of a product or material to withstand changes in temperature in a vacuum environment. Other tests are done to understand how the test article withstands exposure to radiation.

Vacuum testing labs are used by a variety of industries, including aerospace, medical, and defense. These labs are common for material process testing and used in R&D. Vacuum testing helps to identify potential problems with products and materials before they are used in a real vacuum environment. Engineers use this type of testing to improve the performance of products and materials and ensure they meet the required standards. Contact Interfaced to explore your options.

Can load cells be used in a vacuum environment?

Load cells can be used in a vacuum environment. However, not all load cells are created equal or suited for this specialized use case. Some load cells are designed that make them appropriate for vacuum environments, while others are not. Load cells that are not engineered to perform in vacuum environments may not be able to withstand the low pressures and outgassing that can occur in a vacuum. Using quality load cells that are manufactured by force measurement experts in sensor technologies is important in any consideration. It is critical to review the specifications and requirements with a qualified applications engineer.

Key considerations when choosing a load cell for a vacuum environment:

  • Outgassing: Load cells that are used in vacuum environments will have low outgassing rates. This means that they will not release gases into the vacuum chamber, which can contaminate the environment and interfere with measurements.
  • Mechanical strength: Load cells must be able to withstand the low pressures that can occur in a vacuum. They will also be able to withstand the conditions that can be generated by vacuum processes, such as outgassing and condensation. Form factor and model material of the load cell are important in choosing a load cell for this use case.
  • Temperature range: Load cells will need to operate in a wide range of temperatures. This is important because vacuum chambers can be very cold, especially when they are first evacuated, or when they are used to simulate high altitudes or space.

If you are looking for a load cell that can be used in a vacuum environment, please review with Interface application engineers to determine if the model fits your test requirements. We also can offer custom solutions to ensure that the load cell maintains the accuracy and performance specifications based on your exact test plan.

Can a load cell be vented for use in a vacuum testing lab?

Technically yes, you can vent a load cell to be used in vacuum. This allows the internal cavity of the load cell to equalize with external vacuum. However, this does not prevent outgassing and can cause the gages and wiring to be subject to humidity and condensation.

Cabling is extremely important when using any sensor in this environment. There are options to make the load cells wireless using Bluetooth technology.

Caution: Interface recommends that all our products used in this type of environment are designed, built, and calibrated for use in this environment. Venting an existing load cell can alter the performance and damage the cell.  By designing the load cell with venting for use, we can ensure that it will meet the vacuum test range.

Interface also can install thermocouples to work with the sensor to detect temperature in this type of testing environment. In fact, our engineers have designed load cells to package the thermocouples inside the form factor for convenience and performance benefits.

Interface engineers have worked with testing labs for decades. We are available to assist with any use case requirements to determine the best measurement solution.

Interface Supports Wind Tunnel Testing

In the development of an airborne vehicle, like a plane or helicopter, wind tunnel systems are used to gather data across a variety of tests related to the aerodynamics of the vehicle’s design. Whether an object is stationary or mobile, wind tunnels provide insight into the effects of air as it moves over or around the test model. Interface is a supplier of measurement solutions used for aircraft and wind tunnel testing.

Wind tunnels are chambers that test small scale model versions of full systems, or in some cases, parts and components, depending on the size and capabilities of the wind tunnel. They work by allowing the engineers to control airflow within the tunnel and simulate the types of wind force that airplanes and other aircraft will experience in flight. Wind tunnels are also used for testing automobiles, bicycles, drones and space vehicles.

By taking careful measurements of the forces on the model, the engineer can predict the forces on the full-scale aircraft. And by using special diagnostic techniques, the engineer can better understand and improve the performance of the aircraft.

The process for measuring the force and how it reacts to this force works by mounting the model in the wind tunnel on a force balance or test stand. The output is a signal that is related to the forces and moments on the model. Balances can be used to measure both the lift and drag forces. The balance must be calibrated against a known value of the force before, and sometimes during, the test.

Interface’s strain gage load cells are commonly used in wind tunnel testing due to their quality, accuracy and reliability. The instrumentation requirements often depend on the application and type of test. The range of options for both load cells and instrumentation vary based on scale, use, cycle counts, and data requirements.

Instrumentation used in wind tunnel testing can be as simple as our 9325 Portable Sensor Display to a multi-channel data acquisition system. Interface analog, digital and wireless instrumentation solutions provide a range of possibilities. As is the case, wind tunnel testing is typically very sensitive. It is important to calibrate the instrumentation before each test to measurement accuracy.

Types of Wind Tunnel Tests Using Force Measurement Solutions

  • Lift and drag: Load cells are used to measure the two most significant forces that impact aircraft design. Lift is the force that acts perpendicular to the direction of airflow and keeps the craft airborne. Drag is the force that acts parallel to the direction of airflow and opposes forward motion.
  • Side force: This force acts perpendicular to both the direction of airflow and the lift force. It is caused by the difference in pressure between the upper and lower surfaces of the aircraft.
  • Moments: Moments are the forces that act around a point. The most common moments measured in wind tunnels are the pitching moment, the yawing moment, and the rolling moment.
  • Stability and control: Tests conducted to measure the stability and controllability of an aircraft are commonly using force measurement solutions for aircraft design changes or integrating new parts into an existing model.
  • Performance: Particularly important with new designs, engineers use these tests to measure the simulated flight performance under maximum speed, range and fuel efficiency.

The specific tests that are conducted in a wind tunnel depend on the project requirements.

Multi-Axis Sensors for Wind Tunnel Testing Applications

In measuring the forces of a wind tunnel test, multi-axis sensors offer the perfect solution for collecting as much data as possible across every axis, giving the engineer a more complete picture on the aerodynamics of the plane. In fact, Interface has supplied multi-axis load cells for use in several wind tunnel testing applications, for OEMs, testing facilities and part makers.

We offer a variety of multi-axis options including 2, 3 and 6-axis standard and high-capacity configurations depending on testing and data requirements of the user. These sensors can precisely measure the applied force from one direction with little or no crosstalk from the force or moment. Interface products provide excellent performance and accuracy in force and torque measurement.

To match the demands of the volumes of data available using multi-axis sensors in wind tunnel testing, Interface often provides several data acquisition instrumentation solution along with our BlueDAQ software.

Wind Tunnel Test Application

A major aerospace company was developing a new airplane and needed to test their scaled model for aerodynamics in a wind tunnel, by measuring loads created by lift and drag. Interface Model 6A154 6-Axis Load Cell was mounted in the floor of the wind tunnel and connected to the scaled model by a stalk. The wind tunnel blew air over the scaled model creating lift and drag, which was measured and compared to the theoretical airplane models. The output of the 6-axis sensor was connected to the BX8-AS Interface BlueDAQ Series Data Acquisition System, which was connected via USB cable to a computer. Using this solution, the company was able to analyze the collected data and made the necessary adjustments in their design to improve the aerodynamics of their theoretical airplane models.

Interface supports wind tunnel testing and all uses of force measurement in the advancements in aeropspace.

Wind tunnel testing is critical to the aircraft industry, as well as other industries like automotive and space. Interface has been providing multi-axis sensors and strain gage load cells to industry leaders and wind tunnel operators. We understand the unique needs of this type of testing and the instrumentation options that work best with our high-accuracy sensors. We also can work to provide custom solutions, load cells for use in extreme environmental conditions. Contact us to get the right solution for your specific testing program.

Rigging engineers typically work in maritime, construction, manufacturing, entertainment and energy industries. Interface is also seeing a growing demand for sensor technologies used by rigging engineers that work in aerospace, both for aircraft and space vehicle manufacturers.

The use of load cells to measure the weight of heavy loads, such as cranes, ships, rockets, theater equipment and machinery is on the rise. Rigging engineers use the data from load cells, load pins, load shackles, and tension links to ensure that the loads are not overloaded and that the rigging systems are properly designed for each use case. This often requires pairing the high accuracy sensor with instrumentation. For versatility wireless telemetry systems are useful for rigging engineers.

These vital engineering positions are responsible for rigging up and down cranes, loading and unloading ships, or moving heavy equipment around a factory floor. Rigging engineers that design and plan rigging systems for lifting and transporting heavy loads across various industries rely on accurate measurement data. They often oversee the rigging of heavy loads, ensuring that it is done safely and efficiently. They inspect rigging equipment for wear and tear, and make repairs as needed while maintaining records of rigging operations. Sensors and instrumentation play an important role.

Load cells are an important tool for rigging engineers. They provide valuable information that can be used to ensure the safety of rigging operations, whether they are for mooring tension tests in the maritime industry or for lifting an aircraft for wind tunnel testing. Load cells can be used in a variety of ways by rigging engineers. For example, they can be used to:

  • Monitor the weight of a load in real time. This information can be used to make sure that the load does not exceed the safe lifting capacity of the rigging system. Sensors are often integrated into conveyor systems, hoppers, and other equipment to measure the weight or force being exerted. These devices are often used in industries like mining, agriculture, and manufacturing.
  • Create a load map. A load map is a visual representation of the weight distribution of a load. This information can be used to ensure that the load is evenly distributed, and that the rigging system is properly designed no matter the size of structure or component.
  • Set overload limits. Overload limits are set to prevent the rigging system from being overloaded. If the weight of a load exceeds the overload limit, an alarm will sound, and the rigging system will be shut down.
  • Record load data. Load data can be recorded and used to track the weight of loads over time. This information can be used to identify trends and patterns that may indicate a need for maintenance or repairs.
  • Secure equipment. The information from force and weight sensors is critical when lifting and securing equipment, such as appartus used in the entertainment sector, from arial arts rigging to stage set-up.

Rigging engineers use load pins, load shackles, and tension links in a variety of applications to measure and monitor loads, weight and tensions in different lifting and rigging operations.

  • Crane and Hoist Monitoring: Load pins, load shackles, and tension links are commonly used in cranes and hoists to measure the load being lifted. These devices can be integrated into the lifting mechanism to provide real-time load monitoring, ensuring that the load remains within safe working limits. Application examples: Gantry Crane Weighing and Crane Force Regulation App Note
  • Heavy Lifting and Rigging: Load measurement technologies are used in heavy lifting and rigging operations to measure the tension in cables, ropes, and other lifting components. By monitoring the tension, rigging engineers can ensure that the load is evenly distributed, and that the lifting equipment is not overloaded. Application examples: Lifting Heavy Objects and Aircraft Lifting Equipment
  • Load Testing: Sensors are utilized in load testing scenarios to assess the strength and performance of lifting equipment, such as cranes, hoists, and winches. These devices provide accurate load measurements during the testing process, helping engineers determine if the equipment meets the required safety standards. Application examples: Rescue Helicopter Hoist Test and Harness Durability Testing
  • Offshore and Marine Applications: Due to the ruggedized designs of Interface load pins, load shackles, and tension links, we see extensive use in offshore and maritime operations. They are employed in various lifting and mooring applications, including lifting heavy equipment onto offshore platforms, measuring tension in mooring lines, and monitoring loads on anchor systems. Application examples: Mooring Line Tension Testing App Note and Maritime Measurement Solutions for Onshore and Submersible Applications
  • Infrastructure and Civil Engineering Projects: Load cells, load pins, load shackles, and tension links are actively used in construction and civil engineering projects for load monitoring purposes. They can be used in applications such as measuring loads on temporary structures, monitoring tension in cables and suspension systems, and ensuring safe load distribution during construction operations. Application examples: Power Line Tension Testing and Monitoring the Seismic Force of a Suspension Bridge

In all these applications, rigging engineers are using crucial data about loads, tensions, and forces, to ensure safety, optimize performance, and prevent equipment failures.

Load cells and measurement solutions can help to prevent overloading of rigging systems, which can lead to accidents and injuries.

Interface Space Economy Solutions

The space economy is rapidly emerging as a leading platform for cutting-edge research, technology, and global economics. With a focus on endeavors such as lunar mining and deep space exploration, Interface is at the forefront of sensor technology, which is driving growth in this dynamic sector, as noted in our new Space Economy Solutions Overview.

The space economy encompasses various sectors, including satellite communication, Earth observation, space tourism, launch services, space manufacturing, and space mining, among others. It involves both public and private entities, including government space agencies, commercial space companies, and research institutions. As sustainability and digital technologies continue to reshape the global economy, Interface precision force measurement solutions are used in scientific research and development (R&D) and deep space discoveries, as noted in Enabling A Look Way Beyond Yonder. As a result, we are poised to play an increasingly critical role in testing the boundaries and opportunities in the space economy.

Leaders in the space sector are using force measurement products in their to design, build, test, secure and launch rockets into outer space. Interface has been involved in many of these projects with some of the space largest organizations in the world,as noted in our NASA case study.  Interface sensor technologies are also used by innovators and education institutions around the world, like the Richard F. Caris Mirror Lab, that are exploring possibilities and testing inventions for our continued exploration and future inhabitation of other planets and galaxies.

Force Measurement Use Cases for Space Launches

There are numerous areas in which force measurement sensors are utilized on a space project. Everything from the motorized equipment at the launch site, to the rocket itself, can be tested using load cells, load pins, and more. Some of the areas in which Interface has been involved in providing solutions for includes structural testing on rockets, launch platforms and landing, commercial launch vehicles, space exploration equipment testing, and even in testing certain equipment used for space travel and food production.

  • Structural Testing: Structural tests are critical to the launch process because the craft’s core components, such as the liquid hydrogen and oxygen tanks, wings, and fuselage, must withstand launch loads of up to nine million pounds of force (lbf). A few years ago, NASA’s Space Launch System (SLS) used Interface load cells to measure the core stage of the rocket. This particular core stage is one of the largest ever built at 27 feet in diameter and more than 200 feet tall.
  • Thrust Testing: A rocket that is fully fueled and ready for launch can weigh up to five million pounds. Therefore, the force necessary to lift the rocket out of the earth’s atmosphere is immense. There are several other factors working against the rocket which need to be compensated for when adjusting thrust force such as drag. Interface has supplied load cells to many aerospace customers to test force and other contributing factors for lifting a rocket into space. These load cells work by being installed underneath a test plate which the rocket engine will sit on. As the engine thrusts, the load cells will calculate the force output of the engine in real-time. This data is used to optimize the engine to determine how much thrust force is needed based on the spacecraft’s total weight and the calculated drag at liftoff.
  • Force Gravity Testing: Force measurement tools also serve many purposes outside of spacecraft testing in the aerospace industry. Interface was involved in a unique application of force measurement with a customer that wanted to develop a system to provide a full range of natural motion for a realistic simulation of reduced gravity environments. The system would be used to simulate weightlessness so astronauts’ crews could learn how to handle microgravity activities, including walking, running, and jumping. The system could also be used for surface operation studies, suit and vehicle development, robotic development, and mass handling studies.

EVENT ALERT! Interface will be showcasing how our load cells, load pins, load shackles, calibration equipement, and instrumentation are used by space technology companies around the world at Space Tech Expo, May 2-4 in Laguna Beach, California.  You’ll find us in Booth 6057 where we we will be highlighting solutions, as captured here:

Space Economy Applications

Space Dock Capture Ring Force Testing Solution

A space company wanted to test their spacecraft docking simulator. They wisedh to test the forces of the actuators used during the “lunge”, when the soft capture ring is lunged forward to latch onto a space vehicle that has been mounted. They also wanted to ensure they are working properly when engaged, and that it does not go past its overload force limit. Interface suggested using multiple WTS 1200 Standard Precision LowProfile™ Wireless Load Cells to be installed to the actuators of the capture ring. Both as wireless solutions, measurements could be recordeded through the WTS-AM-1E Wireless Strain Bridge Transmitter Module, which then can transmit to the WTS-BS-1 Handheld Display or the WTS-BS-6 Wireless Telemetry Dongle Base Station for the customer to record, log, and graph on their computer. Interface’s Wireless Telemetry System successfully measured the forces of the soft capture ring of the space docking port with overload protection.

Rover Landing Gear Solution

A space company wanted to measure the cushioning effect of their rover’s landing legs through a drop test. They want to test how much force the landing gear can absorb until issues are caused in the legs. Interface suggested using the INFRD Platform Scale, which has four shear beam load cells installed at the corners of the scale. A drop test was conducted at different heights, and the results were summed using a JB104SS Junction Box built in the scale. The results are measured and logged on the provided SD card. Results can be also be viewed and logged when the 9330 connects to a PC. The INFRD Platform Scale was able to capture the forces that was implemented onto the rover’s landing gear through these drop tests.

Like many space technology companies, a very well known space exploration leader is utilizing force measurement to stabilize their rocket prior to launch. A YouTube channel named CSI Starbase, examined a few images from a recent launch construction project and pointed out the presence of Interface stainless steel load pins on the site. In the video, CSI Starbase concluded that the load pins pictured must be used for the hold down arms used on the booster of the rocket. This is one of many Innovative Interface Load Pin Applications.

Hydraulic Press Machines and Load Cells

A hydraulic press is a machine that uses a hydraulic cylinder to generate a compressive force by applying a fluid, typically oil, to a piston. The hydraulic press works on the principle of Pascal’s Law, which states that when a fluid is subjected to pressure, it transmits that pressure equally in all directions.

Load cells are commonly used in hydraulic presses to measure the force or weight of the load that is being applied to the press. Load cells are essentially transducers that convert a mechanical force into an electrical signal. Load cells play a critical role in ensuring the safety, quality, and efficiency of hydraulic press operations, as they allow operators to monitor and control the force being applied to the workpiece with a high degree of accuracy and precision.

Are Load Cells Used in Vacuum Environments?

Vacuum testing labs are essential for ensuring that products and materials are safe and dependable in vacuum environments. A vacuum environment is an area where there is little or no matter. This means that there are very few gas molecules present, and the pressure is incredibly low. Vacuum environments are often created using vacuum pumps, which remove gas molecules from an enclosed space.

Vacuum environments are used to simulate the conditions that products and materials will experience in space or other high-altitude environments. These types of testing labs typically have a vacuum chamber that can be evacuated to an incredibly low pressure. The vacuum chamber is then used to evaluate products and materials for a variety of properties. Engineers use vacuum environments in testing for reduced contamination, improving heat transfer, and to reduce the weight of products.

Tests performed in vacuum labs are used to determine the rate at which gases are released from a product or material and the ability of a product or material to withstand a vacuum without leaking. Thermal cycling tests are done to assess the ability of a product or material to withstand changes in temperature in a vacuum environment. Other tests are done to understand how the test article withstands exposure to radiation.

Vacuum testing labs are used by a variety of industries, including aerospace, medical, and defense. These labs are common for material process testing and used in R&D. Vacuum testing helps to identify potential problems with products and materials before they are used in a real vacuum environment. Engineers use this type of testing to improve the performance of products and materials and ensure they meet the required standards. Contact Interfaced to explore your options.

Can load cells be used in a vacuum environment?

Load cells can be used in a vacuum environment. However, not all load cells are created equal or suited for this specialized use case. Some load cells are designed that make them appropriate for vacuum environments, while others are not. Load cells that are not engineered to perform in vacuum environments may not be able to withstand the low pressures and outgassing that can occur in a vacuum. Using quality load cells that are manufactured by force measurement experts in sensor technologies is important in any consideration. It is critical to review the specifications and requirements with a qualified applications engineer.

Key considerations when choosing a load cell for a vacuum environment:

  • Outgassing: Load cells that are used in vacuum environments will have low outgassing rates. This means that they will not release gases into the vacuum chamber, which can contaminate the environment and interfere with measurements.
  • Mechanical strength: Load cells must be able to withstand the low pressures that can occur in a vacuum. They will also be able to withstand the conditions that can be generated by vacuum processes, such as outgassing and condensation. Form factor and model material of the load cell are important in choosing a load cell for this use case.
  • Temperature range: Load cells will need to operate in a wide range of temperatures. This is important because vacuum chambers can be very cold, especially when they are first evacuated, or when they are used to simulate high altitudes or space.

If you are looking for a load cell that can be used in a vacuum environment, please review with Interface application engineers to determine if the model fits your test requirements. We also can offer custom solutions to ensure that the load cell maintains the accuracy and performance specifications based on your exact test plan.

Can a load cell be vented for use in a vacuum testing lab?

Technically yes, you can vent a load cell to be used in vacuum. This allows the internal cavity of the load cell to equalize with external vacuum. However, this does not prevent outgassing and can cause the gages and wiring to be subject to humidity and condensation.

Cabling is extremely important when using any sensor in this environment. There are options to make the load cells wireless using Bluetooth technology.

Caution: Interface recommends that all our products used in this type of environment are designed, built, and calibrated for use in this environment. Venting an existing load cell can alter the performance and damage the cell.  By designing the load cell with venting for use, we can ensure that it will meet the vacuum test range.

Interface also can install thermocouples to work with the sensor to detect temperature in this type of testing environment. In fact, our engineers have designed load cells to package the thermocouples inside the form factor for convenience and performance benefits.

Interface engineers have worked with testing labs for decades. We are available to assist with any use case requirements to determine the best measurement solution.

Interface Supports Wind Tunnel Testing

In the development of an airborne vehicle, like a plane or helicopter, wind tunnel systems are used to gather data across a variety of tests related to the aerodynamics of the vehicle’s design. Whether an object is stationary or mobile, wind tunnels provide insight into the effects of air as it moves over or around the test model. Interface is a supplier of measurement solutions used for aircraft and wind tunnel testing.

Wind tunnels are chambers that test small scale model versions of full systems, or in some cases, parts and components, depending on the size and capabilities of the wind tunnel. They work by allowing the engineers to control airflow within the tunnel and simulate the types of wind force that airplanes and other aircraft will experience in flight. Wind tunnels are also used for testing automobiles, bicycles, drones and space vehicles.

By taking careful measurements of the forces on the model, the engineer can predict the forces on the full-scale aircraft. And by using special diagnostic techniques, the engineer can better understand and improve the performance of the aircraft.

The process for measuring the force and how it reacts to this force works by mounting the model in the wind tunnel on a force balance or test stand. The output is a signal that is related to the forces and moments on the model. Balances can be used to measure both the lift and drag forces. The balance must be calibrated against a known value of the force before, and sometimes during, the test.

Interface’s strain gage load cells are commonly used in wind tunnel testing due to their quality, accuracy and reliability. The instrumentation requirements often depend on the application and type of test. The range of options for both load cells and instrumentation vary based on scale, use, cycle counts, and data requirements.

Instrumentation used in wind tunnel testing can be as simple as our 9325 Portable Sensor Display to a multi-channel data acquisition system. Interface analog, digital and wireless instrumentation solutions provide a range of possibilities. As is the case, wind tunnel testing is typically very sensitive. It is important to calibrate the instrumentation before each test to measurement accuracy.

Types of Wind Tunnel Tests Using Force Measurement Solutions

  • Lift and drag: Load cells are used to measure the two most significant forces that impact aircraft design. Lift is the force that acts perpendicular to the direction of airflow and keeps the craft airborne. Drag is the force that acts parallel to the direction of airflow and opposes forward motion.
  • Side force: This force acts perpendicular to both the direction of airflow and the lift force. It is caused by the difference in pressure between the upper and lower surfaces of the aircraft.
  • Moments: Moments are the forces that act around a point. The most common moments measured in wind tunnels are the pitching moment, the yawing moment, and the rolling moment.
  • Stability and control: Tests conducted to measure the stability and controllability of an aircraft are commonly using force measurement solutions for aircraft design changes or integrating new parts into an existing model.
  • Performance: Particularly important with new designs, engineers use these tests to measure the simulated flight performance under maximum speed, range and fuel efficiency.

The specific tests that are conducted in a wind tunnel depend on the project requirements.

Multi-Axis Sensors for Wind Tunnel Testing Applications

In measuring the forces of a wind tunnel test, multi-axis sensors offer the perfect solution for collecting as much data as possible across every axis, giving the engineer a more complete picture on the aerodynamics of the plane. In fact, Interface has supplied multi-axis load cells for use in several wind tunnel testing applications, for OEMs, testing facilities and part makers.

We offer a variety of multi-axis options including 2, 3 and 6-axis standard and high-capacity configurations depending on testing and data requirements of the user. These sensors can precisely measure the applied force from one direction with little or no crosstalk from the force or moment. Interface products provide excellent performance and accuracy in force and torque measurement.

To match the demands of the volumes of data available using multi-axis sensors in wind tunnel testing, Interface often provides several data acquisition instrumentation solution along with our BlueDAQ software.

Wind Tunnel Test Application

A major aerospace company was developing a new airplane and needed to test their scaled model for aerodynamics in a wind tunnel, by measuring loads created by lift and drag. Interface Model 6A154 6-Axis Load Cell was mounted in the floor of the wind tunnel and connected to the scaled model by a stalk. The wind tunnel blew air over the scaled model creating lift and drag, which was measured and compared to the theoretical airplane models. The output of the 6-axis sensor was connected to the BX8-AS Interface BlueDAQ Series Data Acquisition System, which was connected via USB cable to a computer. Using this solution, the company was able to analyze the collected data and made the necessary adjustments in their design to improve the aerodynamics of their theoretical airplane models.

Interface supports wind tunnel testing and all uses of force measurement in the advancements in aeropspace.

Wind tunnel testing is critical to the aircraft industry, as well as other industries like automotive and space. Interface has been providing multi-axis sensors and strain gage load cells to industry leaders and wind tunnel operators. We understand the unique needs of this type of testing and the instrumentation options that work best with our high-accuracy sensors. We also can work to provide custom solutions, load cells for use in extreme environmental conditions. Contact us to get the right solution for your specific testing program.

With a focus on endeavors such as lunar mining and deep space exploration, Interface is at the forefront of sensor technology, which is driving growth in this dynamic sector, as noted in our new Space Economy Solutions Overview.

The space economy encompasses various sectors, including satellite communication, Earth observation, space tourism, launch services, space manufacturing, and space mining, among others. It involves both public and private entities, including government space agencies, commercial space companies, and research institutions. As sustainability and digital technologies continue to reshape the global economy, Interface precision force measurement solutions are used in scientific research and development (R&D) and deep space discoveries, as noted in Enabling A Look Way Beyond Yonder. As a result, we are poised to play an increasingly critical role in testing the boundaries and opportunities in the space economy.

Leaders in the space sector are using force measurement products in their to design, build, test, secure and launch rockets into outer space. Interface has been involved in many of these projects with some of the space largest organizations in the world,as noted in our NASA case study.  Interface sensor technologies are also used by innovators and education institutions around the world, like the Richard F. Caris Mirror Lab, that are exploring possibilities and testing inventions for our continued exploration and future inhabitation of other planets and galaxies.

Force Measurement Use Cases for Space Launches

There are numerous areas in which force measurement sensors are utilized on a space project. Everything from the motorized equipment at the launch site, to the rocket itself, can be tested using load cells, load pins, and more. Some of the areas in which Interface has been involved in providing solutions for includes structural testing on rockets, launch platforms and landing, commercial launch vehicles, space exploration equipment testing, and even in testing certain equipment used for space travel and food production.

  • Structural Testing: Structural tests are critical to the launch process because the craft’s core components, such as the liquid hydrogen and oxygen tanks, wings, and fuselage, must withstand launch loads of up to nine million pounds of force (lbf). A few years ago, NASA’s Space Launch System (SLS) used Interface load cells to measure the core stage of the rocket. This particular core stage is one of the largest ever built at 27 feet in diameter and more than 200 feet tall.
  • Thrust Testing: A rocket that is fully fueled and ready for launch can weigh up to five million pounds. Therefore, the force necessary to lift the rocket out of the earth’s atmosphere is immense. There are several other factors working against the rocket which need to be compensated for when adjusting thrust force such as drag. Interface has supplied load cells to many aerospace customers to test force and other contributing factors for lifting a rocket into space. These load cells work by being installed underneath a test plate which the rocket engine will sit on. As the engine thrusts, the load cells will calculate the force output of the engine in real-time. This data is used to optimize the engine to determine how much thrust force is needed based on the spacecraft’s total weight and the calculated drag at liftoff.
  • Force Gravity Testing: Force measurement tools also serve many purposes outside of spacecraft testing in the aerospace industry. Interface was involved in a unique application of force measurement with a customer that wanted to develop a system to provide a full range of natural motion for a realistic simulation of reduced gravity environments. The system would be used to simulate weightlessness so astronauts’ crews could learn how to handle microgravity activities, including walking, running, and jumping. The system could also be used for surface operation studies, suit and vehicle development, robotic development, and mass handling studies.

EVENT ALERT! Interface will be showcasing how our load cells, load pins, load shackles, calibration equipement, and instrumentation are used by space technology companies around the world at Space Tech Expo, May 2-4 in Laguna Beach, California.  You’ll find us in Booth 6057 where we we will be highlighting solutions, as captured here:

Space Economy Applications

Space Dock Capture Ring Force Testing Solution

A space company wanted to test their spacecraft docking simulator. They wisedh to test the forces of the actuators used during the “lunge”, when the soft capture ring is lunged forward to latch onto a space vehicle that has been mounted. They also wanted to ensure they are working properly when engaged, and that it does not go past its overload force limit. Interface suggested using multiple WTS 1200 Standard Precision LowProfile™ Wireless Load Cells to be installed to the actuators of the capture ring. Both as wireless solutions, measurements could be recordeded through the WTS-AM-1E Wireless Strain Bridge Transmitter Module, which then can transmit to the WTS-BS-1 Handheld Display or the WTS-BS-6 Wireless Telemetry Dongle Base Station for the customer to record, log, and graph on their computer. Interface’s Wireless Telemetry System successfully measured the forces of the soft capture ring of the space docking port with overload protection.

Rover Landing Gear Solution

A space company wanted to measure the cushioning effect of their rover’s landing legs through a drop test. They want to test how much force the landing gear can absorb until issues are caused in the legs. Interface suggested using the INFRD Platform Scale, which has four shear beam load cells installed at the corners of the scale. A drop test was conducted at different heights, and the results were summed using a JB104SS Junction Box built in the scale. The results are measured and logged on the provided SD card. Results can be also be viewed and logged when the 9330 connects to a PC. The INFRD Platform Scale was able to capture the forces that was implemented onto the rover’s landing gear through these drop tests.

Like many space technology companies, a very well known space exploration leader is utilizing force measurement to stabilize their rocket prior to launch. A YouTube channel named CSI Starbase, examined a few images from a recent launch construction project and pointed out the presence of Interface stainless steel load pins on the site. In the video, CSI Starbase concluded that the load pins pictured must be used for the hold down arms used on the booster of the rocket. This is one of many Innovative Interface Load Pin Applications.
