FIELD: instrument making.
SUBSTANCE: proposed device comprises open magnetic core made of magnetically permeable material, excitation winding, two measurement windings connected in series and matched as required to make the elements of magneto-elastic pressure transducer and power supply. Besides, it comprises second magneto-elastic pressure transducer consisting of second open magnetic core made of magnetically permeable material, second excitation winding, second pair of measurement windings connected in series and matched as required and second power supply Note here that it comprises balancing transformer with input, output and extra windings, narrow-band filter, amplifier, detector and compensator of output signal initial level.
EFFECT: higher noise immunity in pressure measurements.
