| 摘要 |
Optical probes and methods for continuously measuring the temperature of molten metals in vessels are described. The optical probe may include a fiber surrounded by a protective structure that is mounted in a wall of a vessel. The protective structure may include a porous body for flowing gas through the optical probe assembly. A portion of the optical probe may be sacrificial and erode or break away during temperature measurements. Calibrations may be used to correct temperature measurements based on an amount of erosion or removal of the optical fiber. |
