ABSTRACT:
An electro-pneumatic transducer converts an electrical input signal into a proportional (direct or indirect) pneumatic output signal. A circuit will sense the magnitude of the input signal, monitor the output fluid pressure and adjust a piezoelectric beam voltage until a desired output fluid pressure is achieved. The output fluid pressure is controlled by the deflection of a piezoelectric beam which is polarized and will deflect with an applied voltage. The output fluid pressure is monitored by a pressure sensor.
