Abstract:
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; and a 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.
