Paper Abstract

For non-contact measurement of temperature under strong reradiation with the objects having nearly equal temperature levels conventional methods are not accurate. Method in which measurement of two heat fluxes, one of that is descending on surface of object and second is ascending from object, have been developed. Temperature of the object surface is computed in real time by sequential approximation method using the calibration curves that are received by preliminary experimental investigation of corresponding materials. Method was tested for wide range temperature measurement. Comparison of this method with thermocouple measurements shows a very good accuracy even for low temperature range. Original sensors for high temperature and high heat flux application were developed. One of the advantages of sensors is their capability for accurate measurement of temperature under strong convection influence. The system includes also microprocessor and special software for calibration and temperature measurement. Main application of the system is ovens and furnaces for metallurgy, environmental testing chambers and object temperature monitoring.
