Permissible dynamic loading
•
When operating in the alternating load range, the internal and external
squares on the torque/ screw torque transducer may be damaged by edge
pressure. To avoid this, adjust the custom–fitted connection squares so that
they are free of play.

Displaying torque and direction of rotation
Determining direction of rotation
The sign on the display indicates the direction of rotation. When HBM
carrier–frequency or DC–voltage amplifiers are connected to the fitted cable,
the output voltage or display is positive when the torque transducer will turn in
direction of rotation A (see Fig. 5.1).

Determining torque
If a right–handed torque is introduced (i.e. clockwise), a positive output signal
(0...+10V) is produced in conjunction with HBM measuring amplifiers.
