Abstract
A high temperature fluid sensor has a fusible detector including a body having longitudinally extending conductors therein. A first portion of the conductors is confined within the body whereas a second portion of the conductors projects from an end of the body. The second conductor portions are spaced-apart to define a void therebetween. A fusible material is engaged with, and electrically bridges between the second conductor portions. A tapered portion of the sensor permits the molten fusible material to flow away from the second conductor portions. The tapered portion terminates in spaced-apart relationship with the fusible material and thus further defines the void.
