摘要
A device compensates for the an influence of a magnetic field gradient which may be generated due to a component geometry of a component (1). The device includes at least two magnetic field sensors (17, 18) which are arranged outside of the magnetic balance of the ferromagnetic component (1). The at least two magnetic field sensors (17, 18) each have a differing sensitivity. One of the magnetic field sensors (17, 18) is exposed to the influence of the magnetic field gradient to a greater extent compared to the other magnetic field sensor due to its spatial arrangement relative to the ferromagnetic component (1). The one magnetic field sensor may have a sensitivity lower than the other magnetic field sensor.
