とを特徴とする電空変換器。[Claims for Utility Model Registration] A pneumatic system that includes a flapper that is displaced in accordance with the amount of input electricity, a nozzle that is disposed opposite to the displacement portion of the flapper, receives supply pressure, and derives an output pressure, and the output pressure A pressure sensor that converts the output of the pressure sensor into an electrical signal, a signal amplifier that amplifies the output of the pressure sensor, and a control means that compares a set amount of electricity with the output of the signal cut-off amplifier and inputs the output to the flapper. In the air converter, a first opening/closing means configured to be able to release the input air pressure of the pressure sensor to the atmosphere, a second opening/closing means configured to be able to disconnect between the air pressure system and external equipment; a signal reading means for reading the output of the signal amplifier and the second opening/closing means are in a “closed” state;
An electro-pneumatic converter comprising: correction means that uses a change in the reading value of the signal reading means as a correction signal when the pressure sensor is opened to atmospheric pressure by the first opening/closing means.
