ABSTRACT:
A temperature measuring device includes an optical fiber, a metallic protective tube covering the optical fiber, and a heat insulation coating covering the metallic protective tube such that the optical fiber is covered with the metallic protective tube and the heat insulation coating to form a double-covered optical fiber. The heat insulation coating contains carbon particles as an additive. In addition, a radiation thermometer is connected to the double-covered optical fiber, and a tip of the double-covered optical fiber forms a temperature measuring element for collecting and transmitting radiation to the radiation thermometer.
