There, it is rectified and stabilized. With this supply, the strain gauge bridge is fed.

    Torque means clockwise or clockwise torque if the torque acts clockwise when facing the shaft end. In this case a positive electrical signal is obtained at the output. Torque sensors by Lorenz Messtechnik GmbH can measure both, clockwise and counter-clockwise direction.

    The calibration of the sensor is carried out according to the guidelines of the DKD. The surveillance of the calibrating-laboratory takes place by the DKD. At this calibration, the uncertainty of measurement of the torque measuring instrument is determined. Further information can be obtained from Lorenz Messtechnik GmbH.
