FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement of magnetic field parameters based on fluxgate transmitter. Frequency-measuring device based on fluxgate transmitter, designed to measure magnetic field strength, consists of a flux gate fed by a generator, wherein supply of the flux gate is carried out by a generator of modulated rectangular voltage pulses, wherein modulation frequency corresponds to rated frequency of flux gate, and the filling frequency generated by the generator, which feedback circuit includes the flux gate winding output, depends on the measured magnetic field intensity, wherein the frequency readings of the generator are calibrated in units of magnetic field intensity.
EFFECT: high sensitivity of the flux gate, as well as high efficiency of using generation frequency as a useful signal.
