FIELD: measuring.
SUBSTANCE: invention relates to measurement equipment and can be used to measure intensity of an alternating magnetic field and temperature generated in a controlled area by industrial equipment. Meter of intensity of an alternating magnetic field contains a sensor consisting of the main and additional induction windings wound on a ferromagnetic core, and a converter containing the main amplifier, the output of which is connected to the main indicator. Additional winding is introduced, which contains the same number of turns as the main winding, and is connected in series and in antiphase with it; in addition, the converter includes a current source, a low-pass filter, a high-pass filter, an additional amplifier and an additional indicator connected to the output additional amplifier.
EFFECT: broader functional capabilities due to temperature measurement in the working zone of the sensor, which enables to additionally monitor pre-emergency operating modes of rotary machines and turbopump units.
