Tension/compression load cell Model 922

ringstrain gauge2 mV/V

Description
Electric load cells manufactured by ERICHSEN reflect state-of-the-art sensor technology while remaining user-friendly and adaptable to varied requirements. The measuring principle is based on the elongation of high-quality foil strain gauges (DMS).

Application
These force measuring devices are suitable for universal applications where tensile and compression forces must be measured with high accuracy, e.g. in materials testing (ERICHSEN Tensile Testing Machines UNIMAT® and UNIMAT® + UNICONTROL®), in reference measuring equipment and in research and development. They are also suited for industrial use in automation, monitoring press-in processes and joining technology. A comprehensive accessories program is available. Connection to the measuring and display instruments 975 AP, 980 AP and PHYSIMETER 906 MC is possible via an adapter plug.
