Instruments that can be connected
The basic requirements for the trouble-free operation of torque transducers
are:
-
Adequate power supply for the non-contact telemetry
-
Supply for the preamplifier built into the transducer
HBM has various amplifiers available for numerous applications and these
can supply the transducers and process the torque and torque-proportional
signals. The connection details can be found in the operating manual for the
relevant electronic measurement system.

Calibration signal
The torque transducers T32 FNA deliver an additive electrical calibration sig-
nal that can be called from the amplifier.
When pressing a push button on the front panel of the amplifier the supply
voltage is increased from 54V to 74V. The torque transducer responds with
the output of a calibration signal of approximately 12.5kHz
50% of the rated
torque. The precise value is given on the nameplate of the T32 FNA. The am-
plifier has to be adjusted to the precise calibration signal of the connected un-
loaded torque transducer in order to achieve calibration of the measurement
chain.
