Abstract

According to the principle of blackbody radiation, the experimental exploration of high temperature optical fiber temperature sensor was carried out. The high temperature resistant calcium tungstate material was used as the blackbody radiation material to be made the optical fiber radiation probe. Optical power meter was used to measure the optical power of 980nm wavelength in every 10°C in the range of 150-800°C. The fourth-order polynomial was used to fit the relationship between the radiation optical power and the temperature, and the fourth-order optical power and temperature expression with a fitting degree of 0.99953 was obtained. The temperature measurement accuracy was within 1% in the temperature range of 400-800 ℃.
