Calibration signal
The T10FM torque flange delivers an electrical calibration signal that can be
switched at the amplifier end for measurement chains with HBM components.
The measurement flange generates a calibration signal of about 50 % of the
nominal (rated) torque. The precise value is specified on the type plate. Adjust
the amplifier output signal to the calibration signal supplied by the connected
torque flange to adapt the amplifier to the measurement flange. To obtain
stable conditions, the calibration signal should only be activated once the
transducer has been warming up for 15 minutes.
NOTE
The measurement flange should not be under load when the calibration
signal is being measured, since the calibration signal is mixed
additively.
IMPORTANT
To maintain measurement accuracy, the calibration signal should be
connected for no more than 5 minutes. A similar period is then needed
as a cooling phase before triggering the calibration signal again.
Applying a separated extra‐low voltage of 5 V to pin 6 (+) and 7 ( ) on
connector 1 or 3 triggers the calibration signal.
The nominal (rated) voltage for triggering the calibration signal is 5 V
(triggering at U>2.7 V). The trigger voltage is electrically isolated from the
supply voltage and the measurement voltage. The maximum permissible

in measuring mode. Current consumption at nominal (rated) voltage is approx.
2 mA and at maximum voltage, approx. 22 mA.
NOTE
In the case of HBM system solutions, the measuring amplifier triggers
the calibration signal.
