A Torque Gauge is measuring instrument used across all industries to measure the torque or torsion during a test. Applications exist in research and development, laboratory, quality, production and field environment. There are two kind of force gauges today: mechanical and digital torque gauges.

A digital torque gauge is basically a handheld instrument that contains a torque sensor or transducer, electronic part, software and a display. A torque sensor is an electronic device that is used to convert a torque into an electrical signal. Through a mechanical arrangement, the torque being sensed deforms a strain gauge. The strain gauge converts the deformation (strain) to electrical signals. The software and electronics of the torque gauge converts the voltage of the torque transducer into a torque value that is displayed on the instrument.

Test units of torque measurements are most commonly newton.meter (Nm) or pounds.inch(lbin). The peak torque is the most common result in torque testing applications. It is used to determine if a part is good or not. Some examples of torque measurement: screw torque, cap, motor... but most complicated tests can be performed like dynamic torque,...
