Abstract: The sensor has a soft-magnetic planar structure with two flux guides separated by two non-parallel elongated gaps. Two magnetoresistive detectors (102,104) are positioned along the gaps and electrically connected to an electrical source and an electrical measurement unit. Each detector provides an electrical signal indicating relative angle between the direction of the magnetic field and the orientation of the detectors. An independent claim is also included for a signal processing system.
