A compression fitting includes a housing, a compressible seal, a follower and a driving member. The housing includes an axial cavity having a lateral sidewall that includes an axial keyway therein. The cavity terminates at a first end portion thereof at a seat. The compressible seal may receive a signal transmitting lead therethrough, and is disposed within the cavity and seated on the seat. The follower is axially movable within the cavity for selective engagement with the seal for axially compressing the seal against the seat, the sidewall of the cavity and the signal transmitting lead. The follower includes an integral key that extends laterally outward therefrom and is received within the keyway, and an axial bore for accommodation therewithin of the lead. The driving member is rotatably mounted on the housing and engageable with the follower such that rotation of the driving member causes an axial translation thereof.

1. A compression fitting for a sensor for measuring an operating parameter of an apparatus, said sensor including at least one signal transmitting lead, said compression fitting comprising: a housing having first and second end portions and an axial cavity having a lateral sidewall including an axial keyway therein and extending through said housing, said cavity terminating at a first end portion thereof, at a seat;a compressible seal adapted to receive said signal transmitting lead therethrough disposed within said cavity and seated on said seat;a follower disposed within said cavity and axially movable with respect thereto for selective engagement with said seal for axially compressing said seal against said seat, said sidewall of said cavity and said signal transmitting lead, said follower including at least one integral key extending laterally outwardly therefrom and received within said keyway for axial movement therewithin and at least one axial bore therethrough for accommodation therewithin of said lead; anda driving member disposed at said second end portion of said housing, said driving member being rotatably mounted on said housing and engageable with said follower such that rotation of said driving member causes an axial translation thereof, thereby axially translating said follower within said cavity, said key being rotatably constrained within said keyway for preventing rotation of said follower. 2. The compression fitting of claim 1, wherein said housing is externally threaded at said second end portion and said driving member comprises an internally threaded nut adapted to receive said lead therethrough, in threaded engagement with said threaded second end portion of said housing. 3. The compression fitting of claim 2, wherein said internally threaded nut comprises a cap nut including an opening in an end thereof adapted to receive said lead therethrough. 4. The compression fitting of claim 1, wherein said first end of said housing is externally threaded for a threaded attachment to said apparatus. 5. The compression fitting of claim 1, wherein said signal transmitting lead comprises an electrical conductor for transmitting an electrical signal therethrough. 6. The compression fitting of claim 5, wherein said sensor comprises a thermoelectric sensor. 7. The compression fitting of claim 5, wherein said sensor comprises an accelerometer. 8. The compression fitting of claim 1, wherein said lead comprises a tube for the transmission of a fluid pressure signal therethrough. 9. The compression fitting of claim 8, wherein said sensor comprises a pressure sensor. 10. The compression fitting of claim 1, wherein said seat includes a concave end surface and said compressible seal includes a convex end surface engaged with and conforming to said concave end surface of said seat. 11. The compression fitting of claim 1, wherein said seal comprises a compressible elastomeric material. 12. The compression fitting of claim 1, wherein said seal comprises a compressible metallic material. 13. The compression fitting of claim 12, wherein said compressible metallic material comprises a honeycomb. 14. The compression fitting of claim 1, wherein said keyway is generally axially rectilinear and opens to said second end of said housing. 15. The compression fitting of claim 1, wherein said key conforms generally in cross section to said keyway. 16. The compression fitting of claim 1, wherein said housing cavity is generally cylindrical in shape. 17. The compression fitting of claim 1, wherein said follower comprises a piston generally cylindrical in shape and conforming in cross sectional shape to said cylindrical cavity in said housing. 18. The compression fitting of claim 1, wherein said driving member engages said follower in abutment therewith. 19. The compression fitting of claim 1, wherein said at least one axial bore in said follower comprises a plurality of said axial bores. 20. The compression fitting of claim 19, wherein said follower includes first and second ends, said driving member being engageable with said follower at said first end, said second end being provided with an opening therein, each of said plurality of axial bores extending from said first end of said follower to said opening in said second end thereof.
