Abstract:
An electric to pneumatic transducer including a transducer housing with a primary converting housing section and a relay housing section. The primary converting housing section contains feedback and control electronics and an electronic feedback sensor that are electrically connected. The feedback and control electronics are adapted to be connected to an electronic signal input. The primary converting housing section also contains a nozzle and associated flapper control for controlling the output from the nozzle and the primary converting housing section also contains a bleed orifice. The relay housing section contains a relay control chamber with a positive bias spring that exerts a force on an upper control diaphragm and an associated lower control diaphragm that are in turn associated with a combined exhaust and supply valve.
