PCT No. PCT/SE94/00115 Sec. 371 Date Sep. 12, 1995 Sec. 102(e) Date Sep. 12, 1995 PCT Filed Feb. 14, 1994 PCT Pub. No. WO94/28385 PCT Pub. Date Dec. 8, 1994A magnetoelastic torque transducer for electrically measuring torsional stresses in a shaft (1) which is provided with at least one zone (6, 7) with an anisotropy the effect of which is to deflect the magnetic flux density in a direction away from the natural direction along the shaft and where the shaft is of a material which has a geometrically anisotropic microstructure with at least two phases, of which one phase consists of relatively soft-magnetic continuous streaks with magnetoelastic properties and at least one phase has a considerably lower permeability, the deflection of the magnetic flux density in the zone/zones being achieved by mechanically distorting the shaft within the zone/zones. |
