PRECISION THREE-COMPONENT MAGNETOMETRE Russian patent published in 2012 - IPC G01R33/00 

FIELD: measurement equipment.

SUBSTANCE: invention refers to instrumentation equipment and may be used for precision measurement of magnetic fields. A precision three-component magnetometre, comprising the following: two solenoids, a control and registration unit, digital-to-analog converters, "voltage-current" converters, a unit to search for an absolute value of a vector of Earth magnetic field intensity and a Z component, a step motor to incline a vertical magnetometre, magnetic indicating compasses, and also to increase accuracy of detecting a position of coordinates and actual value of Earth magnetic field intensity, there are semiconductor lasers installed on instrument compasses, which radiate in opposite directions and provide for conventional extension of instrument pointers to 100 m, at the same time supply to semiconductor lasers is sent via insulated axes, for effect of needle tips friction there are side coils, besides, to register condition of counters of a digital-to-analog converter there are photodetectors and mirrors to return laser beams to photodetectors installed in directions North, West, South, East at the distance of 50 m from the instrument.

EFFECT: higher accuracy of detecting a position of coordinates and intensity of Earth magnetic field.
