Abstract

Abstract An enclosure for a transducer includes a cylindrical housing and an end cap covering one end of the housing. A coupling ring engages an annular projection on the one end of the housing and a threaded portion of the end cap to hold the two elements in an abutting relationship. The housing has a threaded aperture therethrough. One of a series of different types of plumbing fittings, each having a common threaded projection, has the threaded projection received in the aperture of the housing. The end cap has a threaded aperture therethrough with one of a series of different types of electrical couplings received therein. Each of the couplings of the series has a common threaded projection which is adapted to mate with the end cap aperture. A set of stops is provided to prevent the end cap and the housing from rotating more than 360 degrees with respect to each other.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 69 words
A sensor enclosure comprising: a housing having a cylindrical portion at one end; an end cap having a cylindrical portion abutting the one end of said housing; a coupling ring engaging both said housing and said end cap in a manner which fastens the latter two elements together; and means for preventing said end cap and said housing from rotating with respect to each other more than 360 degrees.
Claim 2
Dependent Claim 69 words
A sensor enclosure comprising: a housing having a cylindrical portion at one end; an end cap having a cylindrical portion abutting the one end of said housing; a coupling ring engaging both said housing and said end cap in a manner which fastens the latter two elements together; and means for preventing said end cap and said housing from rotating with respect to each other more than 360 degrees.
Claim 3
Dependent Claim 28 words
The sensor enclosure as recited in claim 1 wherein said rotation preventing means comprises a first stop on said housing and a second stop on said end cap.
Claim 4
Dependent Claim 35 words
The sensor enclosure as recited in claim 2 wherein at least one of said stops is designed to break upon a torque of a given magnitude being exerted between said housing and said end cap.
Claim 5
Dependent Claim 25 words
The sensor enclosure as recited in claim 2 wherein said second stop is designed to break under rotation force before said first stop will break.
Claim 6
Dependent Claim 22 words
The sensor enclosure as recited in claim 2 further comprising a seal between the abutting surfaces of said housing and said cap.
Claim 7
Dependent Claim 19 words
The sensor enclosure as recited in claim 2 wherein said cap has an aperture therethrough for receiving electrical wires.
Claim 8
Dependent Claim 19 words
The sensor enclosure as recited in claim 2 wherein said housing has an aperture therethrough for receiving a fluid.
Claim 9
Dependent Claim 23 words
The sensor enclosure as recited in claim 1 wherein said coupling ring engages exterior surfaces of both said housing and said end cap.
