[0002] In the technical field of chemical equipment manufacturing today, in order to ensure the safe operation of high-pressure equipment, it is necessary to monitor the outer wall temperature of the metal wall of the high-pressure equipment in real time during the operation of the high-pressure equipment and to alarm when the outer wall temperature exceeds a certain temperature (i.e., over-temperature). The traditional alarm when the outer wall temperature is over-temperature is to pre-weld a fixed part with a thermocouple on the outer wall of the high-pressure equipment, and then install an armored thermocouple on the pre-welded fixed part after the high-pressure equipment arrives at the site, and then add a thermal insulation layer to the pre-welded fixed part. The above-mentioned thermocouple needs to be fixed on the surface of the high-pressure equipment with bolts. When the high-pressure equipment is excessively bent, the thermocouple does not fit tightly with the outer wall of the high-pressure equipment, resulting in inaccurate measurement of the temperature, and at the same time losing the significance of the alarm. Therefore, accurate measurement of the temperature of the outer wall of the high-pressure equipment and timely alarm are of great significance to the safe and economic operation of the high-pressure equipment.
