How to clean dust combustion thermocouples

What are the steps for cleaning dust combustion thermocouples?
The steps for cleaning dust combustion thermocouples are as follows:

Firstly, disconnect the power and allow the thermocouple to cool to room temperature.

Gently remove dust, dirt, and other debris from the outside of the thermocouple using a soft brush or cotton cloth.

Prepare a basin of warm water and an appropriate amount of neutral cleaning agent, and soak the thermocouple in warm water.

Thoroughly clean the surface of the thermocouple with a soft brush and cleaning agent, taking care to avoid strong friction.

After cleaning, wipe the outside of the thermocouple with a clean damp cloth and ensure that the thermocouple is completely dry.

What kind of cleaning agent should be chosen?
Neutral cleaning agents should be used when cleaning dust combustion thermocouples. Neutral cleaning agents will not corrode or damage the thermocouple, and can effectively remove dirt and grease.

3. What cleaning agents are not suitable for use?
Strong alkali or cleaning agents containing solvents such as alcohol should be used to prevent damage to the thermocouple.

Why cool the thermocouple to room temperature?
Cooling the thermocouple to room temperature and cleaning it can prevent cracks from appearing on the thermocouple casing due to temperature differences, thereby extending the lifespan of the thermocouple.

5. Can water be used to directly flush the thermocouple?
It is not recommended to rinse the thermocouple directly with water. Although thermocouples have certain waterproof properties, prolonged immersion in water can affect the performance of the thermocouple. Use a damp cloth or brush for cleaning.

How to determine if the thermocouple is completely dry?
The moisture on the thermocouple can hinder its normal operation, so it is necessary to ensure that the thermocouple is completely dry after cleaning. You can gently wipe the surface of the thermocouple with a clean tissue or cotton cloth. If no water stains are found, it indicates that the thermocouple has completely dried.
