Development of a radiation thermometer for the adaptive steel plant

In this research, we have worked about the radiation thermometer which can be applied to the hazard circumstance such as steel plant. In the results, we have developed radiation thermometer of a measuring range $500-1500^{\circ}C$, accuracy ${\pm}0.1%$, repeatability ${\pm}0.1%$, resolution $0.2^{\circ}C$. We performed extensive field test for 6 months at the hot strip mill in steel plant. Through the test, we have confirmed the reliability of the developed pyrometer.
