  • Description

    This torque sensor is suitable for both static and dynamic measurements in non-rotating torque transmission systems. Typical uses include testing and calibrating power screwdrivers and torque wrenches and measuring reactive torques on test benches. 

    For individual measuring tasks the design of our torque sensors can be adapted to the customer’s installation conditions.

    More application examples:

    • Test structures in the field of precision mechanics
    • Determination of friction torques
    • Acquisition of breakage moments on screw caps
    • Quality assurance in power screwdrivers

    The design has been optimized regarding overall length, weight and volume, so that axial forces up to relatively high limit values and bending moments of up to 20 % of the measuring range have only a small effect to the influence of the measuring element. Four metal film strain gauges are mounted on the measuring element and connected to form a full bridge. When applying AC or DC voltage on the bridge, the mechanical value torque is converted into electrical voltage. The necessary amplifier either delivers a norm signal (0 … 10 V, 0/4 … 20 mA) or – with indicator module – a torque signal truly corresponding to the measured variable.

    The sensor output signal is standardized, so that an exchange of the sensor (spare part) does not require any new adjustment of the measuring chain.
