Model QWFK-8M Miniature Reaction Torque Transducer DESCRIPTION Models QWFK-8M miniature reaction torque transducers is en- in both directions. A modular, stainless steel construction and no gineered for minimum size and to achieve 0.1% maximum non- moving parts provide excellent durability under harsh industrial linearity. Four bonded strain gages are positioned on a special conditions. Potential miniature reaction torque transducer appli- machined portion of the transducer to effectively measure even cations include motor dynamometer, tire braking, twist measure- slight torque motion. These models operate and are calibrated ment, and friction-skid test measurements.
