Shunt signal
The T40FH torque flange delivers an electrical shunt signal that can be acti
vated from the amplifier for measuring chains with HBM components. 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 trans
ducer, to adapt the amplifier to the transducer.
Information
The transducer should not be under load when the shunt signal is being mea
sured, as the shunt signal is mixed additively.
Triggering the shunt signal
Applying a safety extra-low voltage of 5
…
30 V to pins 6 (+) and 7 (
) at con
nector 1 or 3, triggers the shunt signal.
The nominal (rated) voltage for triggering the shunt signal is 5V (triggering at U
> 2.5V), but when voltages are less than 0.7V, the transducer is in measuring
mode. The maximum permissible voltage is 30V, current consumption at nomi
nal (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 measuring voltage.
Tip
The shunt signal can be triggered by the amplifier or via the operating software
in HBM system solutions.
