Abstract:
A sensor for measuring the temperature of a surface of an object, comprising:a cap having a non-deformable end wall of thermally conducting material and a side wall connected thereto, an outside surface of the end wall being shaped to conform to a shape of the object surface to be measured, a surface on an inside of the end wall of the cap that emits electromagnetic radiation having a detectable optical characteristic that is proportional to the temperature of the cap end wall, a light wave guide having one end held within the cap a distance from the radiation emitting element and in optical communication therewith, and a resilient element connected with the cap in a manner to urge the cap outside surface away from the wave guide one end a limited distance in a manner allowing a limited degree of rotational freedom with respect to the wave guide one end, thereby causing the cap end outside surface to firmly engage the object surface when positioned in contact therewith.
