MAGNETOELASTISCHER DREHMOMENTENGEBER MIT NULLPUNKTSTABILISIERUNG

摘要

To reduce hysteresis effects on the output of a magnetoelastic torque transducer subjected to possible overloads, the transducer is constructed with a measuring sleeve which is rigidly attached by its ends to a surrounded measuring axle. A yielding region in which the material of the sleeve deforms plastically relative to the axle in case of an overload is provided between the measuring zones where the magnetoelastic stresses in the measuring sleeve are sensed. A ring of holes can provide a suitable yielding region.
