Abstract: PCT No. PCT/SE95/00289 Sec. 371 Date Sep. 4, 1996 Sec. 102(e) Date Sep. 4, 1996 PCT Filed Mar. 22, 1995 PCT Pub. No. WO95/27191 PCT Pub. Date Oct. 12, 1995A magnetoelastic torque transducer for measuring, in a non-contacting manner, the torque in a stationary or a rotating shaft. The transducer comprises a shaft (1) with surrounding excitation windings (2, 3) and measuring windings (10, 11). Concentrically with the windings, anisotropic measuring zones are created by applying layers (8, 9), for example in the form of copper strips, on the surface of the shaft. The angle between the strips and a generatrix to the cylinder surface of the transducer shaft is in a preferred embodiment chosen to be +/-45 DEG (FIG. 5).
