Fluorescent optical fiber thermometer manufacturing method and fluorescent optical fiber thermometer

摘要

Filling the inside of the cylinder 15 with the mixture M1 in which the fluorescent powder 13 and the ceramic adhesive 14 are mixed, and heating the mixture M1 inside the cylinder 15 at a temperature of 70 degrees or more and 200 degrees or less. It is integrated even at a high temperature by being manufactured by a manufacturing method including a step of curing and forming the phosphor 12 and a step of inserting the tip of the optical fiber tube 11 into the cylinder 15 and abutting the phosphor 12. The present invention provides a method for manufacturing a fluorescent optical fiber thermometer and a fluorescent optical fiber thermometer that have a highly heat-resistant phosphor capable of maintaining the above-described state and can measure temperature with high accuracy even in an environment where a large amount of electromagnetic waves are generated.
