Abstract
Disclosed is a passive, fast-response thermocouple probe for accurately measuring temperatures of fixed or moving areas of surfaces, particularly of lightweight, low-thermal-conductivity materials, with only a minimal modification of their temperatures being caused by the probe's contact therewith. In making the probe, an approximation of the areal heat capacity of the object, the surface temperature of which is to be obtained, is determined. This information is then utilized to determine the required thickness, density, specific heat, and thermal conductivity of the layer of insulating material which is mounted on the mounting block of the probe. A thin, low-areal-heat capacity thermocouple is positioned on the upper surface of the insulating layer, and a thin, low-areal-heat capacity cover film is mounted over the foregoing elements and extends partially down the sides of the mounting block. Electrical lead wires attached to the leads on the thermocouple are then connected to a readout device including a reference junction.
