Temperature measuring device. |
| 摘要 |
A temperature measuring device includes an optical fiber (11), a metallic protective tube (12) for covering the optical fiber, and a heat insulation coating (13) for covering the protective tube. The optical fiber is covered with the protective tube and the heat insulation coating to form a double-covered optical fiber. The heat insulation coating contains particles as an additive having a melting point higher than a temperature of a molten metal being measured. The heat insulation coating can comprises cellulose. <IMAGE> |
