Sensor arrangement has magnetic field sense element that is energized with magnetic field of ferromagnetic inner and outer flux rings, where poles of inner and outer flux rings are oriented in same direction

摘要

The sensor arrangement has a magnetic field sense element that is connected with a magnetic ring (22) around a rotational axis of a rotatable shaft. The ferromagnetic inner and outer flux rings (18,20) are provided with poles (32,34) which are arranged in radial direction of the rotational axis to tap magnetic field of the magnetic ring. The sense element is energized with the magnetic field of the inner and outer flux rings, where the poles of the flux rings are oriented in same direction.
