Instrument assembly systems, housings and methods of mounting instrument assemblies

Abstract

An instrument system includes an instrument assembly having at least one fitting projecting therefrom. The instrument system further includes at least a first housing member including at least one alignment member located therein. The alignment member preferably includes at least one sloped surface which slopes toward at least one seating adapted to seat the at least one fitting of the instrument assembly. The instrument system further includes a second housing member which forms an explosion-proof enclosure with the first housing member to enclose the instrument assembly. The second housing member preferably forms an explosion-proof enclosure with the first housing member via cooperating threading. The instrument assembly can, for example, include electrical components for a combustible gas sensor.
