SOCKET EXTENSION REACTION
TORQUE SENSOR

INSTRUCTION

SHEET

M1644-1204

The OMEGA® TQ103 Series socket extension

socket and drive to measure or verify bolt torque.
The sensor can measure torque in both clockwise
and counterclockwise directions. Any electronic
display or control device which is compatible with
strain gage transducers may be used with the sensor.
The sensors are available in 1/4", 3/8", 1/2", and 3/4"
square drives.

GENERAL CALIBRATION PROCEDURE

To create the calibration curve furnished to you,
the sensor is cycled through the operating range to
develop a stable hysteresis loop. Known loads are
then applied to the sensor by means of dead weights
or a reference load cell in ascending or descending
increments. The data recorded is then best fit to
second degree equations which describ axcending,
descending, and average calibration curves. These
equations are incrementally solved to generatre
theorectical senosr outputs at various loads. The
calibratio sheet supplies you with data points whose
meanings are defined in the Sensor Calibration
diagram (see reverse side).

DIM

torque sensor is ideal for installation between a

Terminal Non-Linearity (N/L): computed from deviations of ascending theoretical data from
a straight line connecting the zero and full scale points.

Terminal hysteresis (HYS): computed from the differences between descending and
ascending theorectical data.

Best fit through zero Non-linearity (BF/0): computed from deivations of average
theorectical data from a straight line through zero with a slope which produces minimum
deviations with average theorectical data.

Best fit through zero outputs and best fit through zero shunt cal values should be used
when the sensor is assumed to be linear. If the instrumentation is capable of correcting the
second order non-linearity, the average outputs and shunt cal output values should be used.
