Abstract:
An arrangement for measuring a force and/or a torque (Mt) on a machine element extending along an axial axis is disclosed. The machine element has a cavity and at least one magnetization region, extending circumferentially around the axial axis in an axial section. The arrangement further includes at least one first magnetic field sensor, a second magnetic field sensor, a third magnetic field sensor and a fourth magnetic field sensor, each of which is designed to individually measure an axial direction component of a magnetic field caused by the magnetization and also by the force or torque (Mt) and each of which lies in the axial section. At least the first magnetic sensor and the second magnetic sensor are arranged in the cavity of the machine element.
