FIELD: physics.
SUBSTANCE: method of measuring pressure involves using a pressure sensor based on a tenso resistor bridge and a temperature sensor and picking up output signals of the bridge and temperature sensor, generating a signal which corresponds to total resistance of the bridge, using that signal and the output signal of the bridge to determine pressure of the medium, using the signal corresponding to total resistance of the bridge, and a signal which is proportional to pressure of the medium, temperature of the bridge, deviation from the temperature determined from the temperature sensor signal from which the pressure measurement error is determined.
EFFECT: reduced pressure measurement error.
