Reaction Torque Sensors, utilize a strain gauge full bridge configuration
that is maintenance free with immovable non-rotating parts that can be used to
check residual torque on a fastener.
For example, our compact TAT200 Mini
Screw Driver Reaction Torque Sensor,
may be used to determine the necessary torque involved to resume tightening and
thus overcoming frictional effects of a fastener.
Torque Sensors employ a freely
rotating shaft within a fixed housing. The rotating shaft couple between a
driving rotating actuator and load, when the rotating shaft is torsionally
stressed, it gives a signal output proportional to the stress. Changes in
rotational speed and load affect the torque that is measured.
for rotary Torque Sensors include
motor testing, engine testing, dynamometer testing, drive train measurements
and gearbox testing.
