Shunt signal

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 transducer should not be under load when the shunt signal is being measured, since the

shunt signal is mixed additively.

The

T40HS 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 shunt signal can be triggered by the amplifier or via the operating software in HBM

system solutions.
