Abstract
A torque sensing transducer sleeve of the magnetostrictive type is attached to a rotatable shaft where torque is to be measured. A shaft is provided on which torque is to be applied and measured. A transducer sleeve of the magnetostrictive type for measuring the torque is attached to the shaft with a nonmagnetic collar interposed between the shaft and the transducer sleeve. The nonmagnetic collar is formed having a shape such that when the transducer sleeve, and the collar are properly positioned on the shaft, the nonmagnetic sleeve exerts circumferential tension on the transducer sleeve producing circular magnetic anisotropy within the transducer sleeve.
