FIELD: technological processes.
SUBSTANCE: pressure transducer for pressure measurement of the technological fluid contains a transducer body, pressure sensor for measuring the pressure of technological fluid. The pressure sensor is located in the body, and there is a hydraulic transmission system. The hydraulic transmission system comprises of the first separation membrane located on the outside of the transducer body; and the first separation tube, extending from the pressure sensor to the first separation membrane; the first ferrofluid, located in the first separation pipe for transmitting a change in pressure of the process fluid near the first separation membrane to the sensor; and an electronic circuit of the transducer located in the body. The electronic circuit of the transducer is configured to receive and process a pressure signal from the pressure sensor.
EFFECT: increase in the capacity of the pressure sensor, thereby increasing the measuring range and improving the signal-to-noise value.
