DIGITAL FERROPROBE MAGNETOMETER Russian patent published in 2012 - IPC G01R33/02 

FIELD: electricity.

SUBSTANCE: digital ferroprobe magnetometer comprising three metering resistors, the first outputs of which are connected to a common bus, and the second outputs are connected to the second inputs of temperature compensation circuits and to the second outputs of ferroprobes, the first outputs of which are connected to inputs of selective amplifiers accordingly, outputs of which are connected to the first inputs of selection and storage devices, the second inputs of which are connected to the second output of a logical control unit, the third inputs are connected to outputs of temperature compensation circuits, and outputs are connected to the first inputs of analog-to-digital converters, the second inputs of which are connected to the third output of the logical control unit, the input of which is connected to the output of a driving oscillator, and the first output is connected to the input of a sinusoid shaper, the output of which is connected to the first inputs of ferroprobes, at the same time the magnetometer comprises a detector and a voltage divider, the input of which is connected to the output of the sinusoid shaper, and the output is connected to the detector's input, the output of which is connected to the first inputs of the temperature compensation circuits.

EFFECT: reduced measurement error.
