PURPOSE:To improve the sensitivity and response property, by bringing the tip of a supporting tube of a thermocouple into contact with and pushing said tip into a protective tube softened by heating and embedding the warm contact point in a sealing part or bringing said contact point into contact with said part. CONSTITUTION:One end of a quartz straight tube 1 used for a protective tube is softened by heating and is sealed and thermocouple wires 4, 5 inserted and held in a quartz tube 3 used as a supporting tube insertable to the tube 1 placing a hot contact point 6 at the tip, are inserted quickly into the tube 1 together with the tube 3 in a state of room temperature and the tip end are brought into contact with the inner face of a sealing part 2 in a softened state of the tube 1 and moreover, is pushed into the part 2 before reducing to a temperature lower than the softening temperature. Accordingly, the sensitivity and response property are improved because the contact 6 is embedded in the part 2 of the tube 1 or is in contact with the inner face. |
