The present invention relates to a method and an arrangement for measuring a force and/or moment on a machine element extending along an axis, using the inverse magnetostrictive effect. The machine element has a magnetization region for magnetization, this region fully encompassing the axis. The arrangement includes at least one first magnetic sensor and one second magnetic sensor, each being designed to measure individually a first and a second direction component of a magnetic field that is caused by the magnetization and by the force and/or the moment. The direction components that can be measured using the first magnetic sensor have differing orientations. Likewise, the direction components that can be measured using the second magnetic sensor have differing orientations. The first magnetic sensor and the second magnetic sensor are arranged around the axis at different peripheral positions.
An arrangement for measuring at least one of a force or a moment on a machine element extending along an axis, in which the machine element includes a magnetization area for a magnetization extending circumferentially around the axis, the magnetization area is permanently magnetized, so that the magnetization is formed by a permanent magnetization,
A method for measuring at least one of a force or a moment, wherein the force or the moment acts on a machine element that extends along an axis and has a magnetization area extending about the axis for a magnetization extending about the axis, the magnetization area is permanently magnetized, so that the magnetization is formed by a permanent magnetization,
