  • DEVICE AND METHOD FOR SENSING TORQUES, TORSIONAL NATURAL FREQUENCIES, AND/OR TORSIONAL OSCILLAITONS WITHOUT CONTACT
    Publication number: 20180306654
    Abstract: The invention relates to a device (14) and to a method for the contactless detection of a torque of a shaft (10) and/or torsional natural frequencies and/or torsional oscillations. The shaft (10) contains a ferromagnetic material. A measurement head (16) facing toward a shaft wall (12) comprises an excitation coil (22) which couples a magnetic field into the shaft (10). The measurement head (16) furthermore contains a number of measurement coils (24, 26, 28, 30), which measure the magnetic field emerging from the shaft (10).
