NAVIGATION THREE-COMPONENT FERROPROBE MAGNETOMETER Russian patent published in 2020 - IPC G01R33/02 

FIELD: measurement.

SUBSTANCE: invention relates to magnetic measuring equipment. Navigation three-component ferroprobe magnetometer further comprises an interference compensator, having three scaling units, first, second and third inputs of which are respectively connected to the first, to the second and third inputs of the interference compensator and to the first, second and third outputs of the magnetometer respectively, and the fourth input of each scaling unit is connected to the output of the stabilized voltage source, each from first to third scale unit comprises first to fourth voltage converters, diagonal input of each of which is connected to first to fourth inputs of scaling blocks, wherein first circuit of diagonal inputs of each bridge converter comprises series connection of two resistances, and other parallel circuit – resistance of potentiometer, movable contact of which is first output of diagonal output, through first resistance is connected to first loading resistance of scaling unit and first input of operational amplifier, and the second output of the diagonal output through the second resistance is connected to the second load resistance of the scaling unit and the second input of the operational amplifier of the first to third amplifying-converting units.

EFFECT: suppression of object interference and miniaturization of the navigation three-component ferroprobe magnetometer with single-wind ferroprobes while ensuring its high measurement accuracy and combined design and placement of its electronic conversion part and deviation interference compensator.
