A method for simultaneous measurement of both temperature and emissivity was developed by using multi-reflecting effect of radiation energy in a cavity. Each relative error of the measurement was within 1% in temperature, and 10% in emissivity respectively.
This method brought forth a new measuring apparatus, which could not only measure the true temperature of a measuring body, but also obtain some surface informations associated with the emissivity. An on-line system of this method was developed. This system is now operated in a coated steel strip process, where it controls the furnace of the process with temperature information and the quality of the coated strips with emissivity information simultaneously.
