ABSTRACT:
The specification discloses a pressure-sensitive transducer including two spaced pressure-sensitive subassemblies having matched parameters and which are electrically coupled together in a manner to minimize the effect of acceleration on the transducer. In one embodiment, each subassembly comprises a pair of piezoelectric crystals attached to opposite sides of a conductive mounting plate. The two plates are supported on opposite sides of an insulated annular spacer ring in a manner to face like poled surfaces of the crystals in the same directions. The crystals are electrically coupled together in parallel by conductors which couple each pair of crystals of a subassembly together and to the mounting plate of the other assembly.
