What is the problem of inconsistency between the actual temperature and the displayed temperature of the high-temperature sintering furnace?

The inconsistency between the actual temperature and the displayed temperature of the high-temperature sintering furnace may be caused by multiple factors. Here are some common reasons and solutions:
Common reasons
Sensor damage or aging:
The temperature sensor of the high-temperature sintering furnace is a key component for measuring the temperature inside the furnace. If the sensor is damaged or aged, it will result in inaccurate temperature measurement and deviation from the displayed temperature.
Control system parameter setting error:
The parameter settings of the furnace temperature control system are crucial for the stability of temperature control. If the parameter settings are improper, such as the PID parameter settings being unreasonable, it may lead to unstable temperature control, causing the actual temperature to be inconsistent with the displayed temperature.
Power supply voltage fluctuation:
During the operation of a high-temperature sintering furnace, if the power supply voltage fluctuates greatly, it will affect the stability of the temperature inside the furnace, resulting in a difference between the actual temperature and the displayed temperature.
Temperature difference inside and outside the furnace:
When there is a large temperature difference between the inside and outside of the high-temperature sintering furnace, there will be a certain error between the temperature readings of the thermocouples inside the electric furnace and the readings displayed on the monitor.
Heating element issue:
Damage or performance degradation of heating elements may also affect the stability and accuracy of the temperature inside the furnace, resulting in inconsistency between the actual temperature and the displayed temperature.
Cooling system malfunction:
If the high-temperature sintering furnace is equipped with a water cooling system or other cooling methods, and the cooling system malfunctions, it may affect the control of the temperature inside the furnace, causing the actual temperature to deviate from the displayed temperature.

Check the sensor:
Check whether the temperature sensor of the high-temperature sintering furnace is damaged or aged, and ensure that its connection is firm, without looseness or damage. If there are any problems, they should be replaced or repaired in a timely manner.
Adjust control system parameters:
Carefully check and adjust the parameter settings of the furnace temperature control system to ensure that key parameters such as PID are set reasonably, in order to improve the stability and accuracy of temperature control.
Stable power supply voltage:
Ensure the stability of the power supply voltage for the high-temperature sintering furnace as much as possible, and avoid voltage fluctuations from affecting the temperature inside the furnace. If necessary, consider installing devices such as voltage regulators to stabilize the power supply voltage.
Reduce the temperature difference inside and outside the furnace:
Where possible, measures should be taken to reduce the temperature difference inside and outside the high-temperature sintering furnace, such as strengthening the insulation performance of the furnace body.
Check and replace heating elements:
Regularly check the status of the heating element. If there is any damage or performance degradation, it should be replaced in a timely manner to ensure the stability and accuracy of the temperature inside the furnace.
Check and repair the cooling system:
If the high-temperature sintering furnace is equipped with a water cooling system or other cooling methods, its working condition should be regularly checked for normal operation. If there is a malfunction or performance degradation, relevant components should be repaired or replaced in a timely manner to ensure good cooling effect.
In summary, the inconsistency between the actual temperature and the displayed temperature in high-temperature sintering furnaces may be caused by various factors. To solve this problem, it is necessary to comprehensively consider various possible reasons and adopt corresponding solutions.
