| Abstract: | The goods of optical fiber transducer and its basic working principle are mainly introduced.Sapphire single crystal fiber is one of the best ray wave-guide materials which are used in high temperature circumstance.The highest temperature which it can measure is 2 000 ℃.When the temperature is higher than 800 ℃,the delicacy and the distinguishing temperature are higher to use single crystal sapphire stick as the head of explorer,which is used in high temperature.The instrument used higher than 800 ℃ has the sensitivity of 1 ℃ and the temperature resolution of 0.1 ℃ at more than 1 000℃,so it is used in the measure of the temperature of CO in coal gas boiler,its accuracy is 0.1 ℃. |
