Abstract

An explosion retaining housing includes a sheet metal member or outer skin which at least in part forms an interior region of the housing. At least one structural element provides additional strength to the member to retain the explosion in the region. The structural element can be inside of, or, outside of the region. The structural element can have a plurality of components which cooperate together to resist the force of an explosion in the interior region.

First claim

1 . An explosion resistant enclosure comprising:
a sheet metal member formed to define, at least in part, an internal region; a gas sensor disposed within the internal region; at least one structural element, wherein the at least one structural element is coupled to the sheet metal member; and one or more openings between the internal region and an exterior of the sheet metal member, wherein the at least one structural element and the one or more openings are configured to provide a flame-proof structure and retain a flame within the internal region from propagating to the exterior of the sheet metal member.

2 . The enclosure of claim 1 , wherein the at least one structural element is coupled to portions of the sheet metal member.

3 . The enclosure of claim 1 , wherein the at least one structural element is separate from the sheet metal member.

4 . The enclosure of claim 3 , further comprising:
a transparent window carried by the at least one structural element; and an explosion resistant seal disposed between the transparent window and the at least one structural element.

5 . The enclosure of claim 1 , further comprising:
end covers joined by the structural element, wherein the sheet metal member is retained between the end covers.

6 . The enclosure of claim 1 , wherein the at least one structural element is within the internal region, or outside of the internal region.

7 . The enclosure of claim 1 , wherein the at least one structural element comprises a plurality of structural elements.

8 . The enclosure of claim 7 , wherein at least some of the structural elements are in the internal region, or outside of the internal region.

9 . The enclosure of claim 1 , further comprising:
a base; and a cover, wherein the sheet metal member is disposed between the base and the cover, and wherein the at least one structural element extends between the base and the cover.

10 . The enclosure of claim 9 , further comprising:
a plurality of structural elements extending between the base and the cover.

11 . The enclosure of claim 10 , further comprising:
processing circuitry disposed within the internal region, wherein the processing circuitry is in signal communication with the gas sensor.

12 . An explosion resistant housing comprising:
a sheet member-type enclosure; a cover which engages the enclosure forming a substantially closed internal region; a gas sensor disposed within the internal region; one or more openings providing gaseous communication between the internal region and an exterior of the sheet member-type enclosure; at least one support member, wherein the at least one support member is separate from the enclosure and the cover, and wherein the at least one support member is coupled to at least one of the enclosure or the cover.

13 . The housing of claim 12 , further comprising: a base that engages the enclosure, wherein the at least one support member extends between the cover and the base and is coupled to both the cover and the base.

14 . The housing of claim 13 , wherein the enclosure comprises cylindrical metal sides and an integral end member.

15 . The housing of claim 12 , further comprising:
processing circuitry disposed within the internal region.

16 . The housing of claim 12 , wherein the one or more opening are disposed at an interface between the cover and the sheet member-type enclosure.

17 . The housing of claim 12 , wherein the one or more openings comprise flame-proof joints.

18 . An explosion resistant housing comprising:
first and second explosion resistant ends; a sheet member disposed between and retained by the first and second explosion resistant ends, wherein the first and second explosion resistant ends and the sheet member define an internal region; a gas sensor disposed within the internal region; one or more openings configured to provide fluid communication between the internal region and an exterior of the sheet member; reinforcing elements which extend between the first and second explosion resistant ends.

19 . The housing of claim 18 , wherein the elements are in the internal region, or outside of the internal region.

20 . The housing of claim 18 , wherein the one or more openings comprise flame-proof joints.
