Abstract: An encapsulated, self-contained gauge transducer to provide output information from a variable pressure source to a variety of output devices such as an indicating gauge. A housing contains a Bourdon tube sealed at both ends and surrounded by a fluid fill of incompressible liquid. Pressure variations from a source are communicated via a diaphragm in the housing wall through the liquid fill to be exerted externally against the Bourdon tube. A magnet is operably connected to the free end of the Bourdon tube for rotational displacement therewith in response to tube deflections imposed by pressure change.

Abstract: An oil receptive casing of a pressure gauge affording improvements for oil fill. Improvements include complete oil coverage over the dial face for undistorted readability and uninterrupted pointer dampening. A gasket seal construction at the casing and Bourdon tube socket joint maintains leak-tight reliability of the casing. An air cushion of controlled volume readily trapped behind the dial face, receives a removably secured safety plug enabling atmospheric venting in event of excessive internal overpressure.
