PURPOSE:To operate the position of a sensor from the outside of a high pressure container, by inserting a sensor attaching shaft into a tubular seat, energizing the shaft outward by a spring, contacting a pushing rod, which is driven by a screw, to the shaft, and closing the pushing rod and the seat by bellows. CONSTITUTION:A temperature measuring sensor S is fixed to the tip of a shaft 6, and the shaft 6 is inserted into a tubular seat 5 of a high pressure container 1. The shaft 6 is energized outward by a spring 8. A pushing rod 10, to which a rotor 11 is attached, is contacted with the shaft 6. Opening holes of the pushing rod 10 and the seat 5 are closed by an airtight manner. When the temperature of a pipe 3 is measured, a handle 13 is rotated and a feed screw 12 is rotated. Then the pushing rod 10 is made to advance, the sensor S is exposed in the pipe, and measurement is performed. After the measurement, the sensor S is retreated and evacuated from a high temperature gas 4. Therefore, the position of the sensor is manipulated from the outside of the container without excessive force, and the life of the sensor can be made long. |
