ABSTRACT:
A differential pressure transducer cell comprises a housing and a pair of spaced diaphragms connected at one end to one portion of the housing and connected at an opposite end to a second portion of the housing. The diaphragms have an outer surface and an inner surface; and the outer surface of each diaphragm is exposed to a pressure. A beam is connected between the diaphragms at the inner surface of the diaphragms. Sensors are also provided on the beam.
