REACTION TORQUE SENSOR OPERATION MANUAL 5
6. Record the value of the signal conditioner

s
output signal and/or numeric display. This
value is the shunt calibration value, or
equivalent torque.
7. It is important to note that the shunt calibration
value is specific for the particular shunt resistor
used. This value, and the particular resistor, are
now matched to the transducer and form a basis
of the transferable shunt calibration.
Recalculating Shunt Calibration Value
The shunt calibration resistor value and the resulting transducer output can be recalculated using the following
formula:
Supplied Transducer Output = New Resistor Value
New Transducer Output Supplied Resistor Value
Shunt calibration is accepted throughout the industry as a means of periodic calibration of a signal conditioner
and transducer between calibrations of known, applied, traceable, mechanical, input values. Consequently, most
all strain gage transducer manufacturers collect and supply shunt calibration data, along with a shunt calibration
resistor, as a standard feature.

Reaction Torque Sensor System Configurations
Typical Reaction Torque Sensor System Configurations
Operation requires the connection of the sensor to a signal conditioner, then to a readout device (if signal
conditioner does not have a display). Strain gage signal conditioners and cable assemblies are available from
PCB.
Operation with a Signal Conditioner
The signal conditioner span and zero must be set before the torque sensor system can be used. The span can be
set using dead weights or the shunt calibration value. Refer to the shunt calibration information in this manual,
and the signal conditioner instruction manual, for proper set-up information.
