Abstract
A shaft (,) experiences torsion about its axis (,) in response to an applied torque (T). A cylindrical magnetoelastic member (,) is secured coaxially about the shaft (,). The magnetoelastic member (,) has first and second spaced apart end portions (,). Each end portion (,) is chamfered at a predetermined angle (&THgr;,, &THgr;,) with respect to a plane (,) extending perpendicular to the shaft axis (,). The magnetoelastic member (,) provides a magnetic field in response to the torsion of the shaft (,). A detector (,) is positioned adjacent to the magnetoelastic member (,) for sensing the magnetic field and providing a signal indicative of the applied torque (T).
