Title:
ASSEMBLY FOR MEASURING AT LEAST ONE COMPONENT OF A MAGNETIC FIELD
Document Type and Number:
WIPO Patent Application WO/2010/091846
Kind Code:
A3
Abstract:
The assembly for measuring at least one component (x, y, z) of an applied magnetic field (H) comprises a surface area made of soft-magnetic material that is applied in the chip plane and separated into two partial regions (5) by a gap (6). The gap (6) is composed of gap sections having different longitudinal directions, and magnetic field sensitive elements (2) are accommodated in one or more gap sections disposed parallel to each other. In preferred embodiments, the sensitivity direction (4) of the magnetic field sensitive elements (2) and the connecting line (6") of the outer gap openings forms angles of 45° or 90°. In further assemblies, several surface areas are present in the chip plane in order to completely capture all magnetic field components (x, y, z). Magnetoresistive sensor elements can advantageously be utilized as magnet-sensitive elements (2).
