A PROBE FOR THE MEASUREMENT OF HIGH SURFACE TEMPERATURES

Abstract

The report describes the design, operation and performance of a probe system with which temperatures can be measured quickly and accurately on a variety of surfaces. In operation the probe is touched to the surface and through its own sensor, heater and electronic servo system is automatically adjusted to the undistorted surface temperature. Extensive testing on a variety of materials (including alumina, stainless steel, titanium, Rene 41, disil coated molybdenum, disil coated columbium, zirconium, and quartz) has shown it generally to have an accuracy of better than 1/2%. The highest temperature measured successfully in intermittent steady state tests was about 2450F (1343C) and in transient tests was 2994F (1645C).
