1. The installation height of the pressure block must be consistent, usually at a height of 150-2000mm above the level;
2. Pressure block welding requires spot welding on three sides. Do not spot weld the thermocouple insertion port, and be careful not to weld the locking screws on the side during spot welding;
3. The wall temperature of the pipeline should be installed symmetrically from top to bottom;
4. The armored thermocouple must be inserted in place and the stop screw must be tightened in place;
5. It is recommended to use a small groove box for the introduction of armored thermocouples;
6. The fixation of armored thermocouples must be replaced with stainless steel wire;
7. The interface between the armored thermocouple and the furnace wall must be wrapped and then threaded into a self-made protective tube for extraction;
8. To prevent settling of the boiler, it is recommended to use a transition junction box and then connect it to the preamplifier with compensating wires;
9. The bridge or protective tube between the furnace wall and the preamplifier should not be enclosed, to prevent high heat flow from directly entering the preamplifier and damaging the components inside (Tianjin Electric Power Construction did not pay attention, which caused damage to the preamplifier);
10. The installation position of the preamplifier should not be too far, otherwise the length of the thermocouple is not enough;
11. The wiring should be correct and reliable.
