TORQUE TRANSDUCERS RANGE OVERVIEW M425 • FF425 • RS425 • SPMK • DU I

2 TORQUE TRANSDUCERS RANGE OVERVIEW DATUM ELECTRONICS The latest technology Datum Electronics Series M425 non-contact rotary Torque Transducers have been designed to fit with most applications and solutions requiring rotary torque measurement. The Torque Transducer fits in line with the drive train or test bed, using standard keyway shafts. A non-contact transmission system provides data directly proportional to torque. In this variant it is supplied as a complete transducer with bearings to support the stator unit on the rotating shaft. It is suitable for most general test rig...
