ABSTRACT:
A pressure-sensing transducer comprised of a diaphragm sandwiched between two discs having substantially non-moving walls forming two adjacent chambers. Concentric electrodes on opposite faces of one of the chambers form a pair of capacitors. Ports are provided in the discs in communication with the chambers for application of fluid pressures. The transducer assembly is mounted in a housing and isolated from shock by fluid tubing supports attaching the ports on opposite sides of the assembly to the housing. The transducer can be formed of a plurality of discs and diaphragms in a sandwiched relationship to produce a family of transducers.
