FLUID FILLED ELONGATE PRESSURE SENSOR

A pressure sensor (100) includes an elongate body (202) which deforms in response to an applied pressure having a cavity (204) formed therein. An isolation diaphragm (214) seals the cavity (204) from a process fluid and is configured to deflect in response to applied process pressure from the proces...

Zusammenfassung:A pressure sensor (100) includes an elongate body (202) which deforms in response to an applied pressure having a cavity (204) formed therein. An isolation diaphragm (214) seals the cavity (204) from a process fluid and is configured to deflect in response to applied process pressure from the process fluid. An isolation fill fluid in the cavity (204) applies pressure to the elongate body (214) in response to deflection of the isolation diaphragm (214) thereby causing deflection of the elongate body (202). A deformation sensor (240) is coupled to the elongate body (202) and provides a sensor output in response to deformation of the elongate body (214) which is indicative of the process pressure.
