STUDY OF A TEMPERATURE MEASURING SYSTEM FOR THE 1000 C TO 2500 C RANGE

Abstract

A radiometer, operating in the UV region was designed and built to automatically measure the surface temperature of a very hot solid surface. The device senses the UV radiation in the 0.32 to 0.38 micron band, self emitted from a small area on the hot solid surface. The temperature measurement accuracy was investigated for large effective fluctuations of emissivity over a temperature range from 1000 to 2500 C, using a W strip lamp for calibration reference. Feasibility models were constructed and operated in room temperature environments. Temperature data was obtained for varying emissivity of Mo in oxidizing conditions. Preliminary considerations were investigated for application of the radiometer in high temperature oxidizing and nuclear radiation environments in airborne vehicle systems. (Author)
