Shunt signal

The T40 torque flange delivers an electrical shunt signal that can be switched
at the amplifier end for measuring chains with HBM components. The
measurement flange generates a shunt 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 shunt signal supplied by the connected torque
flange to adapt the amplifier to the measurement flange.
NOTE
The measurement flange should not be under load when the shunt
signal is being measured, since the shunt signal is mixed additively.

5.1 Triggering the shunt signal

Applying a separated extra low voltage of 5 V to pin 6 (+) and 7 (
or 3 triggers the shunt signal.
The nominal (rated) voltage for triggering the shunt signal is 5 V (triggered
when U>2.5 V). The trigger voltage is electrically isolated from the supply
voltage and the measuring voltage. The maximum permissible voltage is 30 V
When voltages are less than 0.7 V, the measurement flange is in measuring
mode. Current consumption at nominal (rated) voltage is approx. 2 mA and at
maximum voltage, approx. 18 mA.
NOTE
In the case of HBM system solutions, the amplifier triggers the shunt
signal.
