Force Measurement is Fundamental in Material Testing

/0 Comments/in /by

Material tests are run to determine the quality, durability, and resistance of materials for parts and products. Selecting the right material is critical to performance of a product, system, or part, especially as it relates to the environmental factors. It is also core for adhering to regulatory standards and compliance requirements.

Whether it is construction and concrete materials, metals, fabrics, biomaterial, plastics, packaging, or some other matter, material testing is fundamental throughout the entire development lifecycle.

Among the various ways to test materials, force measurement is one of the most important. Common uses of force measurement in material tests include applications to measure hardness, torsion, strength, compression, bending, shear, impact, creep, fatigue, and nondestructive capabilities.

The use of load cells provides an adaptable tool that can be utilized for various types of material tests. Using force measurement sensors help to detect changes in load, which is used to determine the flexibility, strength, or weakness of properties in materials. This is critical for research and quality control.

For example, in metal material testing load cells are frequently used for characterizing and assessing the quality of metallic components and structures. Material test engineers use load cells to accurately measure the tensile strength, compression resistance, and yield properties of metal samples. By subjecting metals to controlled loads and monitoring the metals deformation during tests, Interface load cells provide critical data that informs engineering decisions and quality control processes. Material tests confirm that the metals chosen for products like aircraft structures, automotive components, and sports equipment, meet stringent performance standards. The measurement sensors are also vital for determining the reliability, longevity and safety of metal materials used for any product or part. See other examples of testing in our new Interface T&M Material Testing Overview.

It is the responsibility of a material testing engineer to determine the resilience, safety, and value of materials through mechanical testing, of which material testing is one of the five categories. Ultimately, product designers and original equipment manufacturers (OEMs) rely upon material testing data to ensure their products can withstand the anticipated levels of force during use. They also need to know if the material will stretch or elongate, as well as pinpoint its exact breaking point.

Interface’s robust line of load cells, multi-axis sensors, and data acquisition systems are used for material testing. It is common to have our 1200 LowProfile load cells installed into material testing machines at test labs and onsite. We also supply a variety of miniature load cells and load pins for material testing, depending on the type of equipment and environment used for tests.

High accuracy load cells are essential in material testing due to their precision, versatility, and ability to provide real-time data, which helps researchers and engineers gain a better understanding of a material’s mechanical properties and behavior under different conditions.

If force must be measured, Interface has a solution. This applies to testing materials used for infrastructure, medical devices, aircraft, rockets, vehicles, robotics and consumer goods. As new materials and composites are introduced in revolutionary ways for use in construction, designing light weight products using polymers, and 3D printed components, it is imperative that material tests validate the use case based on high accuracy measurements.

Our force measurement products are being used to gather data from testing materials in applications used for machines, equipment, structures, packaging and more. Here are a few examples of material testing applications.

Inflatable Space Habitat

Inflatable habitats are the newest innovation in the space industry, creating a new interplanetary dwelling for humans to live and work past the Earth’s atmosphere. An innovative space industry company wanted to test the overall design and material of their inflatable habitats by conducting a burst test. Multiple clevises and LP Stainless Steel Load Pins were attached to the in the webbing material that create the inflatable habitat. When pressure was increased within the inflatable habitat, the load pins captured how much force the heavy duty material will hold at specific pressures until it explodes. Interface’s LP Stainless Steel Load Pins successfully measured the amount of force the inflatable habitat could withstand during the burst test.

Material Tensile Testing Load Frame

A customer wanted to conduct a tensile force test on different samples and materials until failure. Materials include plastic, steel, or woven fabric. They wanted to measure tensile strength, yield strength, and yield stress. Interface’s 1200 Standard Precision LowProfile™ Load Cell was installed into the customer’s test frame. The tensile test was conducted, and force results were captured by the load cell and extensometer were synced through the SI-USB4 4 Channel USB Interface Module. These results were then displayed on the customer’s PC with supplied software. With Interface’s force products, the customer was able to determine the tensile strength, yield strength, and yield stress of a variety of different materials.

Material testing is often the first step in any new product development process. With Interface force measurement solutions, our customers can expect industry-leading accuracy, quality and reliability in testing the materials that will go into their next project.

Bending Beam Load Cell Basics

/0 Comments/in /by

Bending beam load cells are a versatile and cost-effective solution for many weighing and force measurement applications. These types of miniature load cells are small in dimension, which makes them ideal solutions for compact testing environments and for embedding into machines or products for continuous performance measurement.

The use of bending beam load cells expands across industries and applications, for weighing scales, medical devices, industrial process controls, robotic designs, packaging machinery and civil engineering projects.

How Bending Beam Load Cells Work

A bending beam load cell converts a force applied to it into an electrical signal by measuring the flexure of the beam. This is done by attaching strain gages to the beam. When the beam bends, the strain gages change their resistance, which is then converted into an electrical signal by a Wheatstone bridge circuit. The output signal is proportional to the applied load.

The bending beam load cell is bolted to a support through the two mounting holes. Under the covers, you can see the large hole bored through the beam. This forms thin sections at the top and bottom surface, which concentrate the forces into the area where Interface’s proprietary strain gages are mounted on the top and bottom faces of the beam. The gages may be mounted on the outside surface, as shown, or inside the large hole.

The compression load is applied at the end opposite from the two mounting holes, usually onto a load button that the user inserts in the loading hole.

MB Miniature Beam Load Cell

  • Lightweight
  • Nonlinearity error 0.02% FS
  • Ideal for OEM applications

Double Bending Beam Cells

A very useful variation on the bending beam design is achieved by forming two bending beams into one cell. This allows the loading fixtures to be attached at the threaded holes on the center line, between the beams, which makes the sensitive axis pass through the cell on a single line of action.

Bending Beam Load Cell Applications

Material testing is a common application for bending beam load cells. This type of miniature load cell measures the forces applied to materials with a high degree of accuracy to determine stiffness, strength and durability of the specimen.

It is quite common to find bending beam load cells in industrial automation machines and robots to precisely measure the forces required for control, safety and efficiency. In robotics specifically, bending beam load cells will measure the force applied to the robot’s arms and grippers. The data is used to control the robot’s movements and to ensure that it is not damaging the objects it is handling.

Aerospace engineering have long used bending beam load cells in design, testing and manufacturing of aircraft and spacecraft. Automotive engineering use bending beam load cells to design and test vehicles for safety and reliability.

Due to Interface’s ability to custom design bending beam solutions that meet strict size, capacity and accuracy requirements, our products are commonly used in medical and healthcare applications.

Bending Beam Application for Medical Device Testing

In this application, the medical device product lab needs to apply known forces to stent and catheters to ensure they pass all necessary strength and flexibility testing. MBP Overload Protected Beam Miniature Load Cell is placed behind the guide wire for the stent or catheter. The motor will spin the linear drive, push the load cell, and guide the wire through the testing maze. The bending beam load cell connects to the DIG-USB PC Interface Module to record and store testing data for analysis. Read more.

Bending Beam Application for Vertical Farming

Vertical farming is the production of produce in a vertical manner using smart technology systems, while indoors using an irrigation system. A wireless force measurement solution is needed to monitor the amount of water being used, to ensure the produce is being watered just the right amount. Interface suggests installing four MBI Overload Protected Miniature Beam Load Cells under each corner of the trays of the produce to accurate measure the weight during watering. A JB104SS 4-Channel Stainless Steel Junction Box connects to each bending beam cell and to a WTS-AM-1E acquisition module. The device wirelessly transmits the sum weight to the WTS-BS-1-HA Wireless Handheld Display for multiple transmitters, and the WTS-BS-6 Wireless Telemetry Dongle Base Station. Interface’s Wireless Telemetry System monitored and weighed the amount of water being used on the produce in this vertical farming system to increase yield and conversation. Read more here.

How Load Cells Are Transforming the Construction Industry

/0 Comments/in /by

The construction industry is one the most universal, growing, and dangerous industries in the world. Interface force measurement solutions are used for all types of construction applications from bridge and high-rise building projects to foundation load tests and structural monitoring. Our sensors and instrumentation are used in crane and heavy lifting operations, material testing and equipment calibration.

Accuracy and quality of all measurement products used for design, testing, monitoring, and equipment evaluations is imperative in protecting the project’s assets and workers. One of the leading causes of construction accidents is overloading equipment. When equipment is overloaded, it can fail, leading to serious injuries. It is essential to utilize high accuracy load cell technologies to measure the amount of force being applied to construction equipment.

Interface force measurement solutions can help to prevent overloading accidents by using the measurement data to ensure that equipment is not being extended beyond its safety capabilities. Force measurement solutions can also be used to monitor the performance of equipment and identify potential problems before they lead to an accident.

Interface offers a wide variety of sensor solutions for construction equipment and material testing. Our load cells offer precise measurements of applied forces, furnishing essential data regarding the structural response under various load circumstances. This data plays a critical role in evaluating structural integrity, detecting potential vulnerabilities, and optimizing design to guarantee the safety and dependability of infrastructure.

Interface force measurement solutions can help to improve efficiency and productivity in the construction industry in all areas including engineering, testing and maintenance. By monitoring the performance of equipment, construction companies can identify areas where they can improve efficiency.

It is common to find Interface load cells, including load pins, load shackles, miniature and even jumbo load cells in use for various forms of construction projects, equipment and tools. These products, as well as torque transducers, instrumentation and wireless systems are frequently used in the testing and monitoring of the machinery, rigging and lifting devices, gear, and heavy duty vehicles that are used in various stages of building.

Interface provides various sensors for a range of construction use cases around the world, including:

  • Residential and commercial buildings
  • Infrastructure programs
  • Industrial construction
  • Material testing machines
  • Civil engineering projects
  • Mining and tunneling

Construction is an ever-present and ever-growing industry estimated to reach nearly $13T in global spending with broad and diverse use of measurement solutions. From single dwelling construction tools to heavy machines used to move concrete slabs, measurement is fundamental in construction. Included below we have provided a few examples of how our sensors are being used in construction.

Construction Reach Stacker

A reach stacker is a vehicle used in construction site to lift, move, and stack heavy containers. A force monitoring system was needed to ensure the safety of surrounding personnel, and if the reach stacker can lift heavy loads. Interface’s WTSLP Wireless Stainless Steel Load Pins were installed into the corners of the lifting mechanism of the reach stacker, where heavy loaded containers are lifted and moved.

Interface Manufacturing and Production Solutions

/0 Comments/in , /by

Force measurement is integral to advanced manufacturing systems, especially when it comes to how this technology is used in production lines. Force sensors are utilized in both testing and monitoring of a wide variety of machines to ensure accuracy and repeatability throughout the production line. These sensors are also used by production line engineers in the design and development of systems used to ensure accuracy in measurements of force, weight, compression, and torque as products and components move throughout the line, including distribution.

Watch how Interface provided an industrial automation solution for small pallets used in the distribution of manufactured products. In the video, we highlight a request for a pallet weighing solution to use in their warehouse to monitor their products and goods 24/7. They need to use sensor technologies to verify if any products are missing based on the weight, and able to determine pricing for their goods based on the weight.

Interface works with a large range of manufacturers and equipment makers to improve quality and productivity by supplying high-performance measurement solutions. From using miniature load cells to apply the exact force needed to press a brand identity onto fragile consumable, to using multi-axis sensors for verifying performance data when making intricately machined parts, Interface products are commonplace in manufacturing and production.

In fact, Interface offers manufacturing and production standard off-the-shelf, engineered to order and complete OEM solutions including load cells, instrumentation and weighing devices. Our products provide the quality and durability necessary within industrial environments. In addition, we can customize the majority of our products to fit unique and evolving needs as sensor technologies like robotics and advanced manufacturing devices are integrated into production lines.

Load cells are frequently used in monitoring equipment. Interface can custom design force sensors to be installed directly into product for monitoring certain forces in real-time, including for use in industrial automation robotics. This is particularly popular in manufacturing because you can monitor equipment to understand when it may be out of alignment and needs to come down for repair, rather than risking a disruption in production. This is particularly important in automated production lines because it gives engineers and extra set of eyes on machines and improves efficiency overall by reducing downtime.

One of the unique use cases for load cells used for monitoring is in weighing materials held on pillow blocks bearings. Pillow block bearings, or similarly constructed bearing, are used to carry rolled materials or conveyor belt.

A customer has a feed roller system and needs to monitor the forces of both ends of the rollers, in order to maintain a constant straight feed. They would also prefer a wireless system. Interface came to the rescue with our Pillow Block Load Cells and WTS Wireless Telemetry Systems. Interface suggests installing two PBLC Pillow Block Load Cells at both ends of the bottom roller to measure the forces being applied. The forces are measured when connected to WTS-AM-1E Wireless Strain Bridge Transmitter Module. The data is then transmitted wirelessly to the WTS-BS-6 Wireless Telemetry Dongle Base Station and the WTS-BS-1-HA Wireless Handheld Display for multiple transmitters, where data can be displayed, graphed, and logged on the customer’s computer.

Production Line Conveyor Belt Adhesion Test

A customer wants to test the adhesion strength in between the many layers and textiles of a conveyor belt. They want to conduct a separation test from the rubber of the conveyor belt from the other layers. They would also like a wireless solution. Interface’s SMA Miniature S-Type Load Cell is installed in the customer’s tensile test load frame, where it measures the forces applied as the test is conducted and the layers are pulled and separated. When connected to the WTS-AM-1F Wireless Strain Bridge Transmitter Module, the data is wirelessly transmitted to WTS-BS-5 Wireless Analog Output Receiver Module with nV output. The WTS-BS-5 can then connect to the 9330 Battery Powered High Speed Data Logging Indicator to display, graph, and log the data with supplied BlueDAQ software.

Interface Solutions for Production Line Engineers

/0 Comments/in /by

Due to the influence of IoT, AI and big data, the role of production line engineer has become far more critical as manufacturers demand peak efficiency. These engineers need to stay current in automation technologies used to design, build, and monitor a production line for the benefits of decreasing speed to market, lowering costs, and improving outputs at the highest quality standards.

Among the many software and hardware solutions these individuals must also understand connected sensors are among the most important. Sensors are the nervous system of an automated production line, telling which machines must perform certain tasks, when, and how. They are a source for smart factories and smart manufacturing.

Sensors modernize manufacturing, assembly, and production lines by enabling real-time monitoring and control of the production process.

Measurement solutions provide accurate data on production parameters such as temperature, speed, pressure, force, and other relevant variables, which can then be used to optimize the production process, detect, and resolve problems in real-time, and prevent downtime. Additionally, sensors can be integrated into industrial IoT systems to provide valuable insights and analytics that can help manufacturers make data-driven decisions.

One of the sensor types that play a key role in these automated production lines are force sensors. Force sensors can be used by production line engineers across several different facets of an automated line. When designing a manufacturing line, there are quite a few factors that go into the full system. This includes process monitoring, quality control, predictive maintenance, energy management and inventory management. Force sensors play a role in each of these types of data points and processes.

For instance, a production line engineer can install sensors onto a machine that outputs a great deal of torque and monitor that torque to ensure the components creating that force are running smoothly, or if there are certain indicators that say it needs to be pulled off the line briefly for maintenance. When products on the line trigger certain force parameters such as weight, this can also tell the automated production line it is ready for the next stop in the process. Production line engineers design these lines around the sensing capabilities available and connected force sensing products have made a major difference in helping things become more efficient.

There is another automated process that also requires force sensors that is used as part of a manufacturing line, or as a standalone system – robotics. Production line engineers are doing a great deal of research and development into robotics to automate process that are repetitive, or far too delicate for human hands. Force sensors, in this use case, are used in both the testing of robotics to ensure accuracy or developed into the robotics to monitor certain functions over time.

Robotics can improve assembly and production processes, leading to higher efficiency, improved quality, and reduced costs. As technology continues to advance, the use of robotics by production line engineers in assembly and production is likely to become even more widespread.

Here at Interface, we have a great deal of experience in developing solutions for industrial automation and manufacturing lines. We have developed a few application notes to outline how production line engineers use our sensor solutions and force measurement products.

6-Axis Force Plate Robotic Arm

A customer wanted to measure the reaction forces of their robotic arm for safety purposes. The reaction loads occur at the robotic arm’s base; therefore, they needed a force measurement system at the base of the robotic arm. Interface suggested using their force plate option to install at the base of the robotic arm. Four 3-Axis Force Load Cells were installed between two force plates, then installed at the bottom of the arm. This creates one large 6-Axis Force Plate. The sensors force data is recorded and displayed through the two BX8 Multi-Channel Bridge Amplifier and Data Acquisition Systems onto the customer’s PC or laptop. Interface’s 6-Axis Force Plate was able to successfully measure the reaction forces of the customer’s robotic arm. Read more here.

Press Load Monitoring

Press forming is a method to deform varied materials. For instance, materials such as steel can be bent, stretched, or formed into shapes. A force measurement solution is required to monitor the forces being applied by the press forming machine. This ensures quality control and traceability during the production process. For large press forming machines, Interface recommends installing the 1000 High-Capacity Fatigue-Rated LowProfile™ Load Cell. When the material is placed under the punch plate to form a shape, the force applied is measured by the 1000 Series Load Cell. The force results captured is sent to the INF-USB3 Universal Serial Bus Single Channel PC Interface Module, where results can be graphed and logged on the customer’s PC with provided software. Interface’s force measurement products and instrumentation accurately monitored and logged the force results of the press force machine, ensuring zero-error production performance.

Snack Weighing and Packaging Machine

A snack manufacturing brand wanted to weigh the amount of their snacks that is automatically dispersed into the bags during the packaging process. In this case, they wanted to weigh their potato chips being packaged. The company also wanted to ensure the potato chips are at the exact weight needed due to regulatory standards to be distributed out to consumers in the public. Interface’s solution was to use multiple SPI Platform Scale Load Cells, and install it to the potato multi-head weigher and packaging machine. The SPI Platform Scale Load cells were installed inside of the mount that attaches the head weigher to the packaging machine. Force results from the potato chips were read by the load cells and sent to the ISG Isolated DIN Rail Mount Signal Conditioner, where the customer is able to control the automated production from their command center. Using this solution, the customer was able to determine the weight of the potato chips being distributed into their bags with highly accurate results. They also were able to control the automated production process with the provided instrumentation. They will use this same weighing method for other snacks that need to be packaged. Read about the solution here.

Production line engineers turn to Interface due to our quality, accuracy, and reliability. Our products are used to test, monitor in real time, and created automated processes within a manufacturing line. As automation and robotics grow, you will continue to see new applications for sensors in this sector.
