  • Patent number: 4193294
    Abstract: A force measuring magnetoelastic transducer includes a core of magnetostrictive material with apertures, in which excitation and measuring windings are arranged, and between which a measuring zone is formed, in which the dominating part of the magnetomotive force is consumed and in which the stress therefore determines the output signal of the transducer. The core further includes apertures for controlling the force flux, which are so arranged that some measuring zone portions are substantially subjected to compressive stress and other measuring zone portions are substantially subjected to tensile stress when a force is acting on the transducer. Means are provided for exciting the transducer with an alternating current of such magnitude that the signals generated by said compressive and tensile stresses, within a predetermined range of load, show deviations from linearity with negative sign for compressive stress and positive sign for tensile stress.
