| 摘要 |
The present invention relates to an arrangement for measuring a force and/or a torque (Μt) on a machine element (01) extending along an axis (03), using the inverse magnetostrictive effect. The machine element (01) has at least two magnetization regions (04, 05) for magnetization purposes, extending circumferentially around the axis (03). In addition, there are magnetically neutral regions, each region being arranged axially between the magnetization regions (04, 05) and/or axially next to the magnetization regions (04, 05). The arrangement further comprises at least one first magnetic sensor (11), a second magnetic sensor (12) and a third magnetic sensor (13), each of which is designed to individually measure a 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 a different axial position. According to the invention, the third magnetic sensor (13) lies in an axial position of one of the magnetically neutral regions. |
