FIELD: measuring equipment.
SUBSTANCE: invention relates to electric measuring equipment and can be used in devices for measuring parameters of weak constant magnetic field. Measuring device based on ferroprobe transducer comprises ferroprobe excitation winding consisting of two anti-wound halves L1' and L1'', connecting capacitor C1, through which is fed the ferroprobe excitation winding, D flip-flop, modulating rectangular signals generator 1, generator 2 of unipolar modulated rectangular pulses of increased frequency, at that excitation of excitation by means of rectangular pulses is supplied through D-trigger with formation of bipolar signal with double acting value of voltage supplied to excitation winding through connecting capacitor; wherein in device resonant phenomena are used in formed serial circuit "connecting capacitor – ferro-probe excitation winding" at frequency of modulated signal of excitation winding input, wherein said modulating signal represents rectangular pulses with repetition frequency corresponding to that of ferroprobe.
EFFECT: high sensitivity of the measuring device.
