Paper Abstract

In this paper, double surface pyrometer, one with a preceded reflector and another with a preceded absober, are used to measure on-line true temperatures and emissivities of the oxided steelplate and a kind of paint. The main error in the measurement of emissivities comes from the temperature increase of the thermosensor with the preceded absober.When the temperature of the absorber is 40°C and the temperature of the measured surface is above 400°C, the Systematic relative error measuring emissivity is less 5%.
