DIGITAL FERROPROBE MAGNETOMETER Russian patent published in 2015 - IPC G01R33/02 

FIELD: measurement equipment.

SUBSTANCE: digital ferroprobe magnetometer includes a setting generator, the output of which is connected to the input of a logic control unit, the first output of which is connected to the input of a sinusoid shaper, the output of which is connected to the first inputs of three ferroprobes, the outputs of which are connected to inputs of three selective amplifiers, the first outputs of which are connected to the first inputs of three sampling-storage devices, the first outputs of which are connected to the second inputs of three ferroprobes, and the second inputs are connected to the second output of the logic control unit, the third output of which is connected to the second inputs of analogue-to-digital converters, in addition, it includes three adding amplifiers and three sampling-storage devices of quadrature voltage, the first inputs of which are connected to the fourth output of the logic control unit, the second inputs are connected to the second outputs of selective amplifiers, and outputs are connected to the second inputs of the adding amplifiers, the outputs of which are connected to the first inputs of the analogue-to-digital converters, and the first inputs are connected to the second outputs of sampling-storage devices.

EFFECT: increasing stability of a measurement channel of a magnetometer, accuracy and stability of measurements.
