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.

Interface's use of the Wheatstone bridge is considered world-class in load cell design and for its ability to produce accurate measurements. Selecting the right instrumentation and ensuring proper bridge completion are technical necessities for maintaining the integrity of your force measurement data. Our bridge completion solutions simplify selecting the right instrumentation device to pair with your sensor, making it easier than ever to achieve high-quality measurements.

Interface 1200 and Model 1201 Series IO-Link Universal and Compression-Only Load Cells are IO-Link compatible load cells that offer precision force measurements with the benefits of digital communication. They connect directly to an IO-Link Master without requiring any additional electronics. This not only simplifies installation but also ensures a clean, noise-free digital signal. The digital point-to-point connection of IO-Link offers a manufacturer-independent, fieldbus-independent communication technology. IO-Link allows intelligent connection of sensors and actuators to automation systems. The comprehensive, standardized communication with each IO-Link capable sensor enables additional sensor data, transmission of measurement and switching signals without losses, and numerous independent diagnostic functions.
