Abstract
This invention relates to a pressure transducer adapted to transduce or convert fluid pressure into air pressure on a one-to-one basis for control or indication purposes. The transducer includes a diaphragm held between two sealing members and clamped by a transducer body against a mounting member to permit flexing of the diaphragm in either direction such as to be capable of operation in either atmospheric or vacuum environments. An adjustable nozzle in the transducer body permits adjustment of a vent passage in the transducer body relative to the diaphragm to insure a one-to-one conversion of fluid pressure to control pressure.
