Displaying torque and direction of rotation

Torque
If a right hand torque (clockwise) is initiated, there is a positive output signal
(0...+10 V).
Direction of rotation
The sign on the display indicates the direction of rotation. With HBM measuring
amplifiers, the output voltage or display is positive, if the transducer shaft is
turning clockwise, looking at the measuring side.

Maintenance

Torque transducer T20WN is largely maintenance free. We recommend that
the low friction special bearing should be replaced at the Darmstadt factory,
after approx. 20 000 working hours. The calibration will also be checked at this
time.
