Shunt signal
T40B A3452-10.0 49
7 Shunt signal
The T40B torque flange delivers an electrical shunt signal
that can be activated from the amplifier in 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 transducer to
adapt the amplifier to the transducer.
Information
The transducer should not be under load when the shunt
signal is being measured, as the shunt signal is mixed
additively.
Triggering the shunt signal
Applying a separated extra‐low voltage of 5 to 30 V to
pins 6 (+) and 7 ( ) at 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 con
sumption at nominal (rated) voltage is approx. 2 mA and
at maximum voltage, approx. 18 mA. The voltage for trig
gering 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.
