Shunt signal

The T40FM torque flange delivers an electrical shunt signal that can be activ­
ated from the amplifier for measuring chains with HBM components. The trans­
ducer 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.
Information
The transducer should not be under load when the shunt signal is being meas­
ured, as 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 (
plug 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 nom­
inal (rated) voltage is approx. 2 mA and at maximum voltage, approx. 18 mA.
The voltage for triggering the shunt signal is electrically isolated from the supply
and measuring voltage.
Tip
The shunt signal can be triggered by the amplifier or via the operating software
in HBM system solutions.
