Abstract
Disclosed is a pressure-sensing transducer in which a transducing unit comprising a semiconductor-type strain element is confined within a housing defining a generally funnel-shaped chamber. The unit is supported within the housing in spaced relationship with the surface of the chamber by an electrically non-conductive cup-shaped member of relatively rigid material, and a resilient electrically non-conductive ring which is yieldably deformed by sealing engagement of outer peripheral surface portions of the ring with the chamber and the inner cup surface of the member, and the inner periphery of the ring with the outer circular surface of the unit. A viscous flow-resistant, electrically non-conductive liquid occupies any open space in the chamber for communicating pressure from a pressure source through the small end of the chamber to the element within the unit.
