Shunt signal
The torque flange delivers an electrical shunt signal that in measuring chains with HBM
components, can be activated from the amplifier. The transducer generates a shunt signal
of about 50% of the nominal (rated) torque, the precise value is specified on the type
plate. After activation, adjust the amplifier output signal to the shunt signal supplied by the
connected transducer to adapt the amplifier to the transducer.
The transducer should not be under load when the shunt signal is being measured, since the
shunt signal is mixed additively.
Triggering
the
shunt signal
Applying a separated extra-low voltage of 5 - 30 V to pins 6 (+) and 7 (-) at connector 1
or 3 triggers the shunt signal.
The nominal (rated) voltage for triggering the shunt signal is 5 V (triggering at U > 2.5 V),
but when voltages are less than 0.7 V, the transducer is in measuring mode. The
maximum permissible voltage is 30 V, current consumption at nominal (rated) voltage is
approx. 2 mA and at maximum voltage, approx. 18 mA. The trigger voltage for the shunt
signal is electrically isolated from the supply voltage and the measurement voltage.

The shunt signal can be triggered by the amplifier or via the operating software in HBM
system solutions.
