Hagstraße 10 · 74417 Gschwend w w w.eth-messtechnik.de Datasheet Torque Sensor Torque ranges from 1 Nm up to 10.000 Nm Square drive and either with or without angle function Features DRFN • No service needed because of contactless data acquisition • High noise immunity due to amplified active signal • High accuracy due to frequency modulation and strain gage technology • Single power supply • Optional angle detection • Integrated sensor-detection chip for use with GMV2 analyzer The sensor is suited for the most varied measurement duties on threaded fasteners, to check and adjust assembly tools, like screwdrivers and spanners, and to sense loosening torques, etc. It can also be deployed in blocked mode to test torque wrenches. The device is powered wirelessly and the Suitable for automotive industry test benches assembly applications pulsed tools electrical output is wireless, as well. Hence, there is practically no wear on the device. This sensor is suited for cyclical as well as continuous testing of tools. As the sensor is designed to be torsionally rigid any errors due to it are minimized. Models / Fittings Static retainer / clamping device for torque wrenches Subject to change without notice
