FIELD: pneumatic units for measurement of temperatures. SUBSTANCE: device has sensitive element, differential amplifier, non-linear member, secondary instrument, two pneumonic resistors, tuning pneumonic resistor, stabilized supply source, one-sided valve and stabilized supply regulator. First input of regulator is connected to out of first pneumonic resistor and input of tuning pneumonic resistor through single-sided valve. Second input of regulator is connected to output of second pneumonic resistor and to input of sensitive element. Third input of regulator is connected to output of power supply source. Output of regulator is connected to input of differential amplifier. EFFECT: enhanced accuracy of measurement at abruptly changing temperature. 3 dwg
