Force Measurement is Fundamental in Material Testing

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.

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.

Calibration Curve 101

Calibration curves are essential for ensuring the accuracy of force measurements. They are used in a wide variety of test and measurement applications, including quality control, research, and engineering.

A calibration curve is a graph that shows the relationship between the output of a measuring instrument and the true value of the quantity being measured. In force measurement, a calibration curve is used to ensure that the force measuring device is performing accurately. In the context of load cell calibration, a calibration curve is a graphical representation of the relationship between the output signal of a load cell and the applied known loads or forces.

The load cell user will use a known force standard to create the calibration curve. The known force standard is applied to the force measuring device and the output of the instrument is logged via the supporting instrumentation. This process is repeated for a range of known forces.

The calibration curve for a load cell is created by plotting the output signals (typically in voltage or digital units) on the y-axis against the corresponding applied loads or forces on the x-axis. The resulting graph is the calibration curve.

Test and measurement professionals use the calibration curve to convert the load cell output to the true value of the force being measured. The curve helps to establish the relationship between the load and the output signal, and it provides a means to convert the load cell’s output into accurate force or weight measurements. For example, if the output is 100 units when a known force of 100 N is applied, then the calibration curve will show that the measurement using the load cell is accurate to within a certain tolerance.

Benefits of using a calibration curve in force measurement:

  • It ensures that the force measuring instrument is accurate and dependable.
  • It provides a way to convert the load cell output to the true value of the force being measured.
  • It can be used to identify and correct errors, including drift, sensitivity, overload and hysteresis.
  • It should be used for traceability and to track the performance of the measurement device over time.

Why does a calibration curve matter when calibrating load cells?

Load cells can be affected by a range of factors, including temperature variations, drift, and environmental conditions. The calibration curve helps identify and compensate for these factors. By periodically calibrating the load cell, any deviations from the original calibration curve can be detected, and appropriate corrections can be made to ensure accurate and reliable measurements.

The calibration curve for a load cell should be linear, indicating a consistent and predictable relationship between the applied load and the output signal. However, load cells may exhibit non-linear behavior, such as sensitivity variations or hysteresis, which can be accounted for and corrected through calibration.

The calibration curve allows for the determination of the load cell’s sensitivity, linearity, and any potential adjustments or corrections needed to improve its accuracy. It serves as a reference to convert the load cell’s output signal into meaningful and calibrated measurements when the load cell is used in practical applications for force or weight measurement.

Calibration curves are an essential tool for ensuring the accuracy of force measurements. They are used in a wide variety of applications, and they offer several benefits. If you engage in using load cells, it is important to understand the importance of calibration curves and how they can help you ensure accurate measurements.

Interface Solutions for Lifting Applications

Lifting is the action of raising an object to a higher level or moving an object to a different position. Tension load cells accurately measure forms of lifting, as they measure pulling by design. Choosing the right sensor for this type of measurement requires consideration of the size of object that is lifted, and mechanism used in the act to create the lift. Read more in our latest case study Cranes and Lifting.

Often large capacity load cells are used in industrial equipment, cranes, forklifts, rigging, and even aircraft testing equipment to measure forces applied in heavy lifting and for load monitoring, as well as to maintain accuracy in movement. Larger capacity load cells can range from 10,000 to million lbf, or even larger. Rugged load cells are frequently selected for this type of equipment to sustain harsh environmental conditions for both testing and during real-time use.

Smaller capacity load cells, such as s-types and miniature beams, measure the lift action in machines, medical equipment, packaging, robotics, drones and moving equipment. In all circumstances, force measurement sensors help product engineers and manufacturers improve safety and the quality of products they build. They are versatile and easily integrated into machines and components.

Beyond the measurement specifications, other top feature considerations when selecting the right sensor include weight of the sensor, requirements for overload protection, enclosures and ruggedized material used to construct the device, signal outputs for data, cabling, or wireless functionality, mounting or clamping, and instrumentation for data acquisition.

For measurement in lifting applications, Interface products provide the industry’s most accurate and reliable data available through force measurement sensors. Products we provide for lifting include multi-axis sensors, load washer load cells, low profiles, miniature load cells, load shackles, load pins, tensions links, instrumentation, and torque transducers.

The following are examples of products we supply for lifting equipment and use cases.

AERIAL BOOM LIFT OPERATION

They wanted to test several types of material types. The 3D printing materials to be tested to see how it performed included PLA, PETG and ASA.  The test of the materials was to assess strength, quality, ductility, and stiffness. Interface supplied our most popular load cell, the 1200 Standard Precision LowProfile™ Load Cell, to install into the engineer’s test frame. The tensile test gathered the force results from the load cell that was synced through Interface’s instrumentation solution, the INF-USB3 Universal Serial Bus Single Channel PC Interface Module. The results were displayed on their computer with supplied software from Interface. Read more about this material testing application solution here.

Bike Frame Fatigue Testing

Fatigue testing is a critical material test used to ensure the materials used in a product hold up over time. A bike manufacturing company wanted to perform a fatigue test on their bike frames to analyze the strength of their frames, ensure durability and high-quality standards. Interface suggests installing Model 1000 Fatigue-Rated LowProfile™ Load Cell to the customer’s bike frame fatigue tester. This load cell will provide the customer highly accurate results through the fatigue cycling. Results are collected using the INF-USB3 Universal Serial Bus Single Channel PC Interface Module and displayed on the customer’s computer with Interface’s provided software. The bike manufacturing company successfully had their bikes undergo fatigue frame testing, receiving highly accurate results with Interface’s load cell and instrumentation. Watch the fatigue testing of the bike frame in this animated app note.

Spring Compression Testing

A customer wanted to evaluate the performance of their springs, but also the functionality of their spring test stand with a wireless solution. Interface suggested using one of their WTS-5200XYZ 3-Axis Force Moment Load Cell which has three integral WTSAM-1E Wireless Transmitters and installing it into the customer’s spring compression frame. The WTS-5200XYZ 3-Axis Force Moment Load Cell measured the force compression of the spring. The integral WTS-AM-1E Wireless Strain Bridge Transmitter Modules transmitted and displayed the information wirelessly to the LCCAXXX Wireless Instrument Enclosure. Using Interface’s solution, the customer was able to wirelessly get compression results on the spring being tested. They were also able to verify their spring compression test stand was working effectively.
