About the QWLC-8M Miniature Reaction Torque Sensor 

Model QWLC-8M miniature reaction torque transducer is are engineered for minimum size and to achieve 0.1% maximum nonlinearity. Four bonded strain gages are positioned on a special machined portion of the transducer to effectively measure even slight torque motion. These models operate and are calibrated in both directions. A modular, stainless steel construction and no moving parts provide excellent durability under harsh industrial conditions. Potential miniature reaction torque transducer applications include motor dynamometer, tire braking, twist measurement, and friction-skid test measurements.
