Abstract

A fluid sensing device of a fluid within a duct.

First claim

We claim:

1. A sensing unit suitable to sense a parameter of a fluid in an interior of a duct defined by a duct wall having an exterior surface and including a portion defining a duct aperture, said sensing unit comprising:
(a) an enclosure including a first enclosure portion including a mounting surface and arrangement for attachment to said exterior surface of said duct wall with said mounting surface abutting said duct wall;
(b) said enclosure including a second enclosure portion attached to said first enclosure portion and arranged to extend through said duct aperture when said mounting surface abuts said duct wall;
(c) said first enclosure portion of said enclosure defining a first threaded opening for rotational engagement with a first threaded portion of said second enclosure portion of said enclosure for said attachment;
(d) said second enclosure portion including a second portion adjacent said first threaded portion, where said second portion has a diameter less a diameter of said first threaded portion;
(e) a flexible tubular connector interconnecting said second portion to a sensor;
(f) said sensor configured to be in fluid connection with said fluid in said interior of said duct.

2. The sensing unit of claim 1 further comprising said sensor including at least one of a temperature sensor, a humidity sensor, a carbon dioxide sensor, a carbon monoxide sensor, a volatile organic compound sensor, a pressure sensor, a velocity sensor, and a smoke sensor.

3. The sensing unit of claim 1 further comprising said sensor being maintained within said first enclosure portion.

4. The sensing unit of claim 1 further comprising said first enclosure portion including an openable cover.

5. The sensing unit of claim 1 further comprising a third portion of said second enclosure portion adjacent to said first threaded portion, where a diameter of said third portion is greater than said diameter of said first threaded portion, where said third portion is at an opposite end of said first threaded portion than said second portion.

6. The sensing unit of claim 5 wherein said diameter of said third portion is greater than a diameter of said first threaded opening.

7. The sensing unit of claim 1 wherein said second enclosure portion is free from including any openings therein except for one opening at the opposing ends thereof.

8. The sensing unit of claim 1 wherein said second enclosure portion is constructed from metal material.

9. A sensing unit suitable to sense a parameter of a fluid in an interior of a duct defined by a duct wall having an exterior surface and including a portion defining a duct aperture, said sensing unit comprising:
(a) an enclosure including a first enclosure portion including a mounting surface and arrangement for attachment to said exterior surface of said duct wall with said mounting surface abutting said duct wall;
(b) said enclosure including a second enclosure portion attached to said first enclosure portion and arranged to extend through said duct aperture when said mounting surface abuts said duct wall;
(c) said second enclosure portion defining an end opening at an end thereof farthest distant from said first enclosure portion;
(d) said second enclosure portion free from defining any other openings in a side of said second enclosure portion other than said opening at an end thereof
(e) an end cap engaged over an end portion of said second enclosure portion and said end cap engaged over said end opening;
(f) a sensor configured to be in fluid connection with said fluid in said interior of said duct maintained through said end opening within said second enclosure portion.

10. The sensing unit of claim 9 wherein said first enclosure portion of said enclosure is rotationally engaged with said second enclosure portion.

11. The sensing unit of claim 9 wherein said end cap location is maintained with interference friction securement.

12. The sensing unit of claim 9 wherein said end cap is constructed from metal material.

13. The sensing unit of claim 9 wherein said end portion of said second enclosure portion defines exterior threads.

14. The sensing unit of claim 9 wherein said end cap is free from being in pressing engagement with a terminal end surface of said second enclosure portion when fully engaged therewith.

15. The sensing unit of claim 9 wherein said end cap includes a trilobular cross sectional area.

16. The sensing unit of claim 15 wherein said end cap is in direct contact with no more than 35% of the exterior surface of said second enclosure portion directly underneath said end cap.

17. The sensing unit of claim 9 wherein said end cap does not include a symmetrical cross sectional area.

18. A sensing unit to sense a parameter of a fluid in an interior of a duct defined by a duct wall having an exterior surface and including a portion defining a duct aperture, said sensing unit comprising:
(a) an enclosure including a first enclosure portion including a mounting surface and arrangement for attachment to said exterior surface of said duct wall with said mounting surface abutting said duct wall;
(b) said enclosure including a second enclosure portion attached to said first enclosure portion and arranged to extend through said duct aperture when said mounting surface abuts said duct wall;
(c) said second enclosure portion supporting a first pressure sensor and a second pressure sensor;
(d) a sensor included within said enclosure sensing a first pressure from said first pressure sensor and a second pressure from said second pressure sensor;
(e) said enclosure including a display that selectively provides one of a differential pressure measure and a velocity measure based upon said first pressure and said second pressure.

19. A sensing unit suitable to sense a parameter of a fluid in an interior of a duct defined by a duct wall having an exterior surface and including a portion defining a duct aperture, said sensing unit comprising:
(a) an enclosure including a first enclosure portion including a mounting surface and arrangement for attachment to said exterior surface of said duct wall with said mounting surface abutting said duct wall;
(b) said enclosure including a second enclosure portion detachably attachable to said first enclosure portion and arranged to extend through said duct aperture when said mounting surface abuts said duct wall;
(c) said first enclosure portion of said enclosure defining a first opening for engagement with a first portion of said second enclosure portion of said enclosure for said attachment;
(d) said second enclosure portion including a second portion adjacent said first portion, where said second portion has a diameter less a diameter of said first portion;
(e) a flexible tubular connector interconnecting said second portion to a sensor;
(f) said sensor in configured to be in fluid connection with said fluid in said interior of said duct.

20. The sensing unit of claim 19 further comprising said sensor including at least one of a temperature sensor, a humidity sensor, a carbon dioxide sensor, a carbon monoxide sensor, a volatile organic compound sensor, a pressure sensor, a velocity sensor, and a smoke sensor.

21. The sensing unit of claim 19 further comprising said sensor being maintained within said first enclosure portion.

22. The sensing unit of claim 19 further comprising said first enclosure portion including an openable cover.

23. The sensing unit of claim 19
