Abstract (en)

[origin: WO02059555A1] A hand-held unit for measuring torque has a magnetic structure (40) with two-spaced pole ends (44a:44b) of opposite polarity applicable at or adjacent to the surface of a portion (32) of a rotating shaft (30) of ferromagnetic material, the poles (44a:44b) being spaced in the direction of the shaft axis. An axially-directed, surface-adjacent magnetic flux (52) is induced in the local portion of the shaft (30) between the poles. A magnetic sensor device (60) intermediate the poles (44a:44b) is oriented to detect a torque-dependent component of the induced magnetic field external to the shaft surface. The magnetic structure incorporates a magnetic source (16) provided by a permanent magnet (46') or a D.C. or A.C. energised coil (50).
