1, industrial thermocouple installation position, should consider to repair and maintenance is convenient. 2, first of all should be good industrial thermocouple measuring the size of the screw teeth, car good teeth. 3, according to the diameter of the screw tooth holder, the need to measure the hole in the pipeline. 4, the teeth of welding. Inserted the screw tooth holder had been open hole, the screw teeth with measured pipe welding. 5, industrial thermocouple precession is welded teeth. 6, according to the wiring diagram will pick good line, the thermocouple or thermocouple junction box and connected to dial photogenic corresponding digital display table. Terminal box shall be installed under the outlet hole, to prevent bad sealing, water vapor dust deposition such as shorting terminal. Pay attention to the junction box is in contact with the medium of the pipe wall being measured phase, to ensure that the terminal box temperature less than 0 The range of 100 ℃.
