Estimating the term…
The present invention relates to an arrangement for measuring a force and/or a torque (Mt) on a machine element extending along an axis, using the inverse magnetostrictive effect. The machine element has a cavity extending along the axis and at least one magnetization region for magnetization purposes, extending circumferentially around the axis in an axial section of the machine element. 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 and/or torque (Mt) and each of which lies in one of the axial sections of the magnetization regions. According to the invention, at least the first magnetic sensor and the second magnetic sensor are arranged in the cavity of the machine element.
An arrangement for measuring at least one of a force or a torque (Mt) on a machine element that extends along an axis comprising a cavity defined in the machine element and extending along the axis and at least one magnetization area extending circumferentially about the axis in an axial section of the machine element for a magnetization;
