Embodiment Construction

[0018] 1 to 6 depict a preferred embodiment of the instrument assembly system of the present invention comprising a first housing part or body 200 , an instrument assembly 300 and a second housing part or cover 400 . The instrument assembly 300 includes, for example, a frame or housing 302 in which an instrument single or multi-element 500 (such as, for example, the ULTMA® available from the Mine Safety Appliances Company of Pittsburgh, Pennsylvania)  The combustible gas sensor used in the series gas monitor uses a printed circuit board) is connectable. For example, instrument assembly 300 may include a printed circuit board, one or more microprocessors, and a display 510 on its front to provide operators and workers with a readout of the concentration of the gas being analyzed. Instrument assembly frame 302 and instrument element 500 may be formed separately or as an integral unit.

[0019] The housing body 200 includes a first port 270 to which, for example, a sensor housi...

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.

Description

technical field [0001] The present invention relates generally to instrument assembly systems, enclosures and methods for mounting instrument assemblies, and, more particularly, to instrument assembly systems, enclosures and methods for mounting instrument assemblies in explosion proof enclosures wherein alignment of the instrument assemblies is facilitated. Background technique [0002] Mechanical hardware is often used to hold instrumentation components (e.g. sensor components) in enclosures (explosion-proof enclosures in certain environments), which require the use of specialized tools for installation / removal such as, not limited to brackets, nuts, positioning Ring etc. Also, the installer must visually align or position the instrumentation components in the housing before using these tools to secure the instrumentation components. [0003] Aligning and installing multiple instrument components in optimal condition can be difficult. Furthermore, instrument enclosures a...
