Abstract
The Sensor is designed for use in detecting fire, or high temperature in vessels or pipes pressurized with air, gas or liquids. It has a polymer body which confines electrical conductors, and the conductors project 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 has been molded in place. The body has wrenching flats thereabout and tapered pipe threads thereon to allow its installation in the wall of a pressure vessel, pipe, or housing, with the fusible-material end exposed therewithin.
