Abstract
An apparatus is disclosed for obtaining improved heat sensing or temperature measurements using a spring loaded sensor fitting. The apparatus comprises four components in combination being a double ended threaded body; a cylindrical member having adjustable means; an internal compression spring; a retaining threaded member insertion in one end of said body for the purpose of retaining said spring among other useful functions.
Claims4
An improved spring-loaded apparatus for use with a heat sensor and in combination with isolating or thermal wells comprising:
- a double ended male threaded body for attaching to an internally threaded conduit member, said threaded body having an internally bored hole with female threads on one end;
- a cylindrical member located within said internally bored hole in said threaded body, said cylindrical member having adjustable means for selectively rigidly attaching said cylindrical member to said heat sensor at different positions along the length of said sensor;
- an internal compression spring having outside diameter less than the diameter of said internally bored hole in said threaded body, said spring positioned within said threaded body so as to exert a force on said cylindrical member;
- a retaining threaded member having external threads on one end, said external threads mating with said female threads on said threaded body.
