DEVICE FOR INDEPENDENT RECORDING OF PULSE MAGNETIC FIELD Russian patent published in 2014 - IPC G01R33/09 H01L43/08 

FIELD: measurement equipment.

SUBSTANCE: device includes the primary induction transducer, a resistor, a piece of a thin wire, a magnetoresistive bridge and electrical connectors. The transducer includes a magnetic field concentrator and a coil wound on the concentrator. The bridge made as per a thin-film integral technology includes magnetoresistors made from a ferromagnetic alloy having a rectangular hysteresis loop. The coil is connected through the resistor to the piece of the thin wire laid onto the surface of two of four magnetoresistors forming opposite arms of a magnetoresistive bridge. The device is connected through connectors to an information reading unit.

EFFECT: increasing sensitivity of a magnetoresistive device to a measured magnetic field; excluding influence of electrical noises on a measurement result.
