MAGNETORESISTIVE PICKUP Russian patent published in 2003 - IPC

FIELD: automatics, equipment measuring direct and alternating currents and voltages where resistive decoupling of signal source and measuring instrument is required. SUBSTANCE: magnetic system comprising several magnetoresistive strips and forming homogeneous magnetic field in strips in plane of their arrangement, perpendicular to their axis of light magnetization is positioned in plane of arrangement of magnetoresistive strips. Two control conductors are put through insulation layer above strips. EFFECT: development of pickup measuring direct and alternating currents displaying low value of hysteresis. 3 dwg
