【Abstract】 A new sapphire optical fiber high_temperature sensor and its thermometer were developed based on the mechanism of blackbody radiance. Theoretical and experimental studies were made on its thermal radiance. The instrument used from 600 ℃ to 1 800 ℃ has the accuracy of 0.1 ℃ and the space resolution of 1.5 cm. The instrument can be applied both in technological research and industrial enterprises with some specific environment for temperature measurement.更多还原
