MAGNETIC FIELD TRANSDUCER Russian patent published in 2000 - IPC

FIELD: small-sized component magnetometers and devices for determining the orientation of moving objects relative to the geomagnetic field. SUBSTANCE: the magnetic field transducer has a framework with an excitation winding and sections of measuring windings distributed on it, which are connected in pairs in two orthogonal sensitivity axes and opposite in magnetomotive forces. The magnetic core is positioned in one plane. It has four sector ring plates with crescent- shaped ends with non-magnetic gaps between them for replacement and relative shift of magnetic core plates in the process of its balancing with connected process measuring unit. The angles in plan of the four sector ring grooves in the framework make up 85 to 95 deg. EFFECT: enhanced accuracy of measurement of components of external magnetic field. 2 cl, 3 dwg
