ABSTRACT:
An improved housing for a condition responsive indicating instrument which includes a one-piece, integrally-formed casing having a generally circular front support plate whose front surface is adapted for mounting a dial face thereon and a cylindrical wall integral with said support plate and extending rearwardly therefrom to form a cavity for housing the internal mechanisms of the instrument. A "blow-out" back cover normally seals the back of the cavity but is responsive to excessive internal pressure to break the seal to relieve the pressure. The back cover overlays a dual function diaphram which both forms the rear seal and compensates for temperature variations. A bracket is coupled, either directly or indirectly, between the rear surface of the support plate and the central portion of the back cover to prevent relative axial motion therebetween. The housing includes a shock-isolating mounting plate having a first portion secured to the rear surface of the support plate and a second portion integral with the first portion and spaced therefrom for mounting the internal mechanisms so as to at least partially isolate the mechanisms from external forces applied to the instrument.
