Abstract
A temperature sensor is fixedly attached to a thin, flexible disc-like metal plate with sufficient flexibility to conform to the general shape of a surface. The sensor may be thermocouple, a resistor, a semiconductor or other structure. This thin metal member has a low thermal capacity or mass and a relatively high degree of thermal conductance. A tubular insulating and elastic member is fixedly attached to the periphery of the plate and to a tubular housing having an attached handle. The housing functions as a support and an enclosure for the temperature sensitive unit, flexible connecting leads and the like. The elastic member permits the plate to pivot about the housing to move into complete surface engagement with the surface being monitored. The electrical wires connected to the temperature sensitive unit are relatively fine to minimize the thermal mass and capacity added to the unit. The wires are also flexible such that they do not interfere with movement of the plate. An elastic material covers the wire attachment and a short distance therefrom to relieve stress resulting from flexing of the leads. A suitable insulation covers exposed conducting surfaces to minimize creatio…
