Reasons and solutions for the low temperature of the tungku muffle

What should a muffle furnace user do when the electric furnace temperature display is low? What is the reason for this? Is there a solution to this problem? For this series of problems, the editor of Huarong tells you, this This situation is easy to solve.

Let’s first analyze the reason for the low temperature of the muffle furnace:

1. The temperature of the reference terminal of the thermocouple may be too high.

2. Leakage or deterioration of thermocouple electrode.

3. The thermocouple measurement position is too far away.

4. The compensation wire and the thermocouple are connected reversely or mismatched, or the insulation is reduced. Basically these four reasons.

After knowing the reasons, we began to formulate solutions for each reason.

Reason 1: Check the temperature of the reference end to make you meet the temperature requirements.

Reason 2: Check the connection wire of the thermocouple electrode, if there is a leakage, you need to replace the connection wire of the muffle furnace. If the electrode has deteriorated, it must be replaced with a new and identical thermocouple.

Reason 3: Adjust the measuring position of the thermocouple until the measured temperature value is accurate.

Reason 4. Compensation wire, if the muffle furnace wire is connected reversely, just correct it. If i From the above, we can see that when the muffle furnace fails, let’s not panic. First turn off the power of the electric furnace, and then analyze the cause of the failure. After finding the cause, we can seek the correct solution.
