Abstract: In order to compensate for hysteresis in the measuring signal from a magnetoelastic transducer constituted by an iron core and windings arranged in the core for generating a magnetic field in the core and measuring the changes in the magnetic field is occurred when the core is affected by a mechanical force, compensating windings are located in apertures in the core at points where the field strength is considerably lower than around the apertures for the measuring windings and where the mechanical stress condition of the mechanical force acting on the core is different. The signals generated by the measuring windings and the compensating windings are added in such phase position of the signals that the hysteresis component of the compensating signal is in opposition to the hysteresis component of the signal produced by the measuring windings.
