Abstract: The following specification is directed to a pressure responsive transducer utilizing dual diaphragms on opposite sides of a sandwich of substrates formed of ceramic and having an intermediate substrate in which a slot is formed to communicate with the diaphragm chamber and eliminate the need for puncturing and/or sealing of one of the diaphragms. External electrical connections to fixed capacitor plates deposited on the outer substrates of the sandwich are extended by forming a lead on the intermediate substrate which connects to the fixed plates through aligned openings in the substrates, that also communicate the chambers formed by the diaphragms.
