Abstract
A high pressure capacitive transducer includes a capacitive pressure transducer having an insulating diaphragm, and a high pressure fitting for housing the transducer. The high pressure fitting includes a flexible metal diaphragm bonded to the fitting, with the metal diaphragm in engagement with the insulating diaphragm. The metal diaphragm may be boned to the fitting around the periphery of the metal diaphragm to block the high pressure fluid from the transducer. The insulating diaphragm may be relatively thick, such as one-twentieth, one-tenth, or one-fifth of an inch thick, for example.
