摘要:
In order to enable practical suitability of a force or torque sensor and usability for a variety of applications in conjunction with cost-effective production, the invention provides a sensor head (10) for a magnetoelastic force or torque sensor for measuring a force or a torque in a ferromagnetic body (9), comprising: a magnetic field generating unit (14) for generating a magnetic field in the ferromagnetic body (9) and a magnetic field measuring unit (16) for measuring a magnetic field change in the ferromagnetic body (9), wherein the magnetic field generating unit (14) has an excitation coils (18) and a soft-magnetic excitation flux amplifying element (20), wherein the magnetic field measuring unit (16) has a plurality of measurement coil (22) with a soft-magnetic measurement flux amplifying element (24), wherein at least the excitation coil (18) and the measurement coils (22, 22a-22d) are integrated in a common integrated component, such as, in particular, a printed circuit board element (26) and/or MEMS component (28).
