ABSTRACT:
A torque gauge using magnetoelastic ribbons is presented wherein changes in the magnetic characteristics of these ribbons are detectable in a push-pull mode for determining torque forces applied to the ribbons. Respective tensile and compressive forces applied to the ribbons cause a change in the magnetic qualities of the ribbons and of the inductance of coils wound about the ribbons with the change of inductance being a measure of the torque forces applied to the input of the device.
