Precautions for thermocouple installation

(1) Thermocouples should be installed vertically on horizontal or vertical pipelines as much as possible, and protective sleeves should be provided during installation to facilitate maintenance and replacement.

(2) The cold end of the thermocouple should be at the same ambient temperature, and the same compensation wire should be used, with positive and negative connections.

(3) When measuring the temperature inside the pipeline, the length of the component should be on the centerline of the pipeline (i.e. the insertion depth of the protective tube should be half the diameter of the pipe).

(4) When installing the temperature dynamic coil gauge, the opening size should be appropriate and the installation should be aesthetically pleasing.

(5) Use high-temperature resistant cables or high-temperature resistant compensation wires in high-temperature areas.

(6) Choose different measuring components according to different temperatures. Generally, when measuring temperatures above 100 ℃, a thermocouple should be selected, and when temperatures are below 100 ℃, a thermistor should be selected.

(7) The wiring should be reasonable and beautiful, and the pointer indication should be correct.
