Honeywell QWFK-8M Miniature Torque Transducer Datasheet
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.
