Universal testing machines (UTMs) are essential for material qualification, structural research, and quality assurance. Interface load cells sit directly in series with the moving crosshead and the upper specimen grip of a UTM. A machine controller reads the load cell continuously within a closed feedback loop to regulate crosshead travel, maintain constant loading rates, or hold targeted force thresholds during stress relaxation evaluations. The transducer measures the specimen resistance as it deforms. The data acquisition system pairs this instantaneous force data with displacement data to measure elasticity, yield point, and ultimate tensile strength.

Explore Interface’s 2025 Product Recap to see the most popular load cells and torque transducers driving trends in advanced analytics, test lab upgrades, structural and fatigue testing, robotics, digital instrumentation, and miniaturization. By no surprise, Interface's 1200 LowProfile Load Cell remains in the number one spot for load cells. S-types and beams took the top spots and trends toward multi-axis sensors saw a rise in 3-Axis and 6-Axis sensors and systems.

Interface Mini Load Cells are engineered for use in applications that require a light touch, are lightweight, or require less space. The Interface miniature sensor line offers not just small in physical size load cells and torque transducers, they also have a range to test minimal forces with extremely high accuracy. They are making a big impact in industrial automation, aerospace, automotive and medical device OEM products.
