ABSTRACT:
A pressure transducer having a capactive pressure sensing moudle disposed in a housing is biased against a sealing ring disposed in a chamber circumscribing a fluid pressure inlet by a retainer ring mounted in the housing. A selected back-up washer may be used to accommodate various size pressure sensing modules. The housing is sealed from the environs by means of a hermetic glass-to-metal header which mounts terminals to provide electrical coupling to electronics mounted in the housing.
