Interface Accelerates Accuracy in Test and Measurement
Since Interface was founded in 1968, we have developed millions of load cells and torque transducers for engineers and designers that require the highest precision force sensors for accurate and reliable data collection in test and measurement (T&M). Our customers represent a wide swath of industries, products, equipment types, tools, and electronics that depend on us for proving accuracy, consistency, and reliability in performance.
The complexity of user applications and testing environments is rapidly expanding as a result of shorter product lifecycles and demands for smaller, lighter, faster-performing innovations. This has created a proliferation of new test and measurement use cases for sensors in almost every sector including technology, energy, and biomedical, as well as industrial, additive manufacturing and automotive verticals. We are seeing more and more sensor products utilize Bluetooth technology, digital outputs, and direct OEM installations into the product without connectors.
Our products serve a wide variety of these types of test and measurement requirements used for structural and material testing, static and fatigue testing, torsion effects, tension tests and mass and kinetic energy. When experienced users see the Interface brand, they know they can expect the highest-quality results possible from the force measurement industry leaders.
The load cell products we provide T&M customers range from our Ultra Low Capacity Series, which measures forces in mere grams, to our industry-leading LowProfile™ Load Cells with capacities up to 2 million lbf. For torque testing, Interface supplies a wide variety of torque transducers with ranges as low as 0.005 Nm and as high as 340K Nm. We customers depend on us for various multi-axis sensors, instrumentation products, accessories, tension links, load pins, and shackles. For complex challenges and unique applications, our customers work with our application engineers to create modified and customized solutions.
Test and Measurement Applications
To give you a sense as to the range of test and measurement use cases, here is a small sample of applications that utilize our standard and custom force measurement solutions:
- Fatigue testing
- Material testing
- Suspension testing
- Shear testing
- Force testing
- Tensile testing
- Pressure testing
- Friction testing
- Durability testing
- Tension testing
- Device testing
- Hardware load and fatigue testing
- Force verification
Included below are two examples of how our products were used to help our customer’s test and measure “real life” applications.
A customer came to us needing to test the load and durability factors of harnesses used by workers to carry heavy loads or those used in sports equipment. We developed a drop test apparatus using an Interface Model 1200 Load Cell. The apparatus dropped a humanoid dummy outfitted with the harness from various heights to measure the force generated during sudden stops at maximum cable extension. These tests helped our customer develop harness limits which inform users on unsafe loads.

Prosthetic Load and Fatigue Testing
Medical hardware engineers are among the largest users of T&M equipment because of the stringent regulations in the industry. Interface developed a new solution to test heavy loads on prosthetic limbs to certify them for falls, accidents and athletic movement. These stress tests determine the expected lifespan of prosthetic components under normal usage. Our solution involves a static load test apparatus with an S-type load cell attached to a hydraulic actuator which applies and measures cyclic loads. These tests help our customers determine whether prosthetic materials and designs will withstand the rigors of daily use and occasional high-load situations.

What we find most exciting about the T&M industry is continuous innovation, perhaps it is the “engineer” in us. We like to solve, create, build, imagine and challenge ourselves. There are a wide variety of new applications we see every year, and yet many applications are unique.
Those that are in the test and measurement field help to guarantee product safety, reliability and longevity. Therefore, the tools they use are critical to the confirmation of their work. That’s why Interface builds products that reliably and consistently gather high-quality, accurate data for any application.
