ABSTRACT:
The sensor is formed with a polymer body which confines electrical conductors, with the conductors projecting from opposite ends of the body. The conductors' projections at one end define terminal blades, and at the opposite end are shrouded with, and electrically connected by, fusible material that is molded in place. An electrically inert buffer, formed of the same body polymer, is introduced between the conductors at the opposite end, and the fusible material is deposited about the ends and buffer as a cylindrical shell. A V-shaped notch is formed in the buffer for lockingly-engaging the shell. The body has wrenching flats formed thereabout and tapered pipe threads formed thereon to allow its installation in the wall of a pressure vessel, pipe, or housing, with the fusible-material end exposed therewithin.
