How to correctly wire thermocouples with comparison holes

What is a thermocouple with a comparison hole?
A thermocouple with a comparison hole is a device for measuring temperature, which consists of two different metal wires called thermocouple wires. It can measure temperature by measuring the electromotive force generated by the temperature difference of the material.

2. Wiring method for thermocouples with comparison holes
Wiring is a very important step when using thermocouples, and the wiring method for thermocouples with comparison holes is slightly different. The following are the steps for correct wiring:

Preparation: Ensure that the thermocouple wires and wiring terminals are clean and free of impurities.
Identification of wires: Before wiring, use different colored collars or labels to identify two thermocouple wires for correct connection.
Connecting wires: Insert one end of the thermocouple wire into the hole on the wiring terminal and ensure it is securely fixed.
Terminal selection: Select appropriate terminals according to the actual situation to ensure reliable connection.
Grounding: Connect the grounding wire of the thermocouple to the grounding point of the circuit to provide grounding protection.
Fixation: Use insulating tape or other methods to secure the wiring to prevent loosening or breakage.
3. Precautions for thermocouples with comparison holes
When comparing thermocouples with holes in the wiring strip, the following precautions should be taken:

Do not twist the wires: Avoid twisting or excessively bending the thermocouple wires to avoid affecting the measurement results.
Avoid contact with other metals: Ensure that the thermocouple wire does not come into contact with other metals to avoid interference with the measurement.
Regular inspection: Regularly inspect the condition of thermocouple wires and wiring terminals. If there is any damage or looseness, replace or repair them in a timely manner.
Keep clean: Keep the thermocouple wires and wiring terminals clean to ensure the accuracy of signal transmission.
Connecting thermocouples with comparison holes in the correct way can ensure the accuracy and reliability of measurement results.
