徴とする電気／圧力変換機構。 A torque motor generates torque corresponding to the input current to displace the flapper, thereby changing the nozzle back pressure of the nozzle facing the flapper, and amplifying this nozzle back pressure with a pilot relay to output air pressure. In an electricity/pressure conversion mechanism that displaces a lever in response to this pneumatic output and applies negative feedback to the flapper via a spring to generate a pneumatic output corresponding to the input current, the electric/pressure conversion mechanism converts it into a feedback signal related to the pneumatic output. a temperature sensor that measures ambient temperature and converts it into a temperature signal; a multiplexer that switches the feedback signal, the temperature signal, and the input current at a predetermined cycle and outputs a switching signal; An analog/digital conversion means for converting a signal into a digital signal, a microprocessor means for performing signal processing using this digital signal and outputting the result of the calculation, and a digital/analog conversion means for converting the result of the calculation into an analog signal. an electric/pressure conversion mechanism, comprising: a driving means for receiving the analog signal and driving the torque motor; and a modem for transmitting a communication signal to the outside via the microprocessor means. .
