FIELD: measuring equipment.
SUBSTANCE: invention relates to a measuring technique and can be used to measure and control the induction of a magnetic field. Device consists of an excitation module, a ferromodulation transducer and a readout module. Excitation module consists of a current source, a low-pass filter, a control module, first and second key elements, and a controlled current source. Ferromodulation converter includes a ferromagnetic core with excitation windings, readout and compensation. Reader module consists of an integrator, an amplifier and a tunable filter. Device operates in a pulsed mode of measured value, has low power consumption and provides simplicity of technical realization.
EFFECT: expansion of the dynamic range of measurement of magnetic field induction.
