Abstract
A UV radiation detector with a replaceable secondary window for that is easily replaced by an end user thereby increasing the accuracy of UV radiation measurements. The UV radiation detector with a replaceable secondary window generally includes a housing having a primary window, a UV radiation sensor within the housing to measure UV radiation passing through the primary window, a secondary window protecting the primary window from the fluid and a retainer member having an outer opening removably connectable to the housing to retain the secondary window. The secondary window can be easily replaced after becoming contaminated.
Claims20
A UV radiation detector, comprising:
- a housing having a connector end and a primary window, wherein said primary window allows for the passage of UV radiation and wherein said connector end is comprised of a male threaded end;
- a UV radiation sensor within said housing to measure UV radiation that passes through said primary window;
- a secondary window removably attached to said housing for allowing replacement of said secondary window, wherein said secondary window allows for the passage of UV radiation, wherein said secondary window is adjacent to and protects an outer surface of said primary window from contamination;
- and
- a retainer member having an outer opening to allow for passage of UV radiation, wherein said retainer member is removably attached to said housing to removably retain said secondary window adjacent to said primary window, wherein said retainer member includes a female threaded end threadably connected to said male threaded end and an overlapping portion, wherein said overlapping portion is opposite of said female threaded end, wherein said overlapping portion extends inwardly to said outer opening thereby defining a perimeter of said outer opening, wherein said outer opening is smaller than said secondary window, wherein said secondary window is in contact with an interior surface of said overlapping portion and wherein said overlapping portion retains said secondary window adjacent to an outer surface of said primary window.

A UV radiation detector, comprising:
- a housing having a connector end and a primary window, wherein said primary window is integrally formed within said housing and wherein said primary window allows for the passage of UV radiation and wherein said connector end is comprised of a male threaded end;
- a UV radiation sensor within said housing to measure UV radiation that passes through said primary window;
- and
- a secondary window removably attached to said housing for allowing replacement of said secondary window, wherein said secondary window allows for the passage of UV radiation, wherein said secondary window is adjacent to and protects an outer surface of said primary window from contamination;
- a retainer member having an outer opening to allow for passage of UV radiation, wherein said retainer member is removably attached to said housing to removably retain said secondary window adjacent to said primary window, wherein said retainer member includes a female threaded end threadably connected to said male threaded end and an overlapping portion, wherein said overlapping portion is opposite of said female threaded end, wherein said overlapping portion extends inwardly to said outer opening thereby defining a perimeter of said outer opening, wherein said outer opening is smaller than said secondary window, wherein said secondary window is in contact with an interior surface of said overlapping portion and wherein said overlapping portion retains said secondary window adjacent to said outer surface of said primary window.
