Installation and use precautions of furnace tube blade thermocouples

The furnace tube blade thermocouple is a temperature sensor used to measure temperature in high temperature environments, especially suitable for temperature monitoring of high temperature equipment such as furnace tubes. In order to ensure its correct installation and use, the following is a sharing of installation and use precautions.

1. Installation precautions

1. Select a suitable location: Before installation, select a suitable installation location according to the process requirements and site environment. Ensure that the thermocouple can accurately and stably reflect the actual temperature of the furnace tube.

2. Maintain vertical insertion: The installation should ensure that it is inserted vertically into the furnace tube to reduce measurement errors. Avoid tilting or horizontal installation to avoid affecting the accuracy of the measurement results.

3. Reserve enough space: During the installation process, ensure that there is enough space between the thermocouple and the furnace tube to prevent excessive heat concentration from causing damage to the thermocouple.

4. Use suitable connectors: Select connectors that match the thermocouple, such as flanges, gaskets, etc. Ensure that the connection is firm and prevent leakage.

5. Avoid thermal shock: During the installation process, pay attention to avoid thermal shock of the thermocouple to avoid damage to the thermocouple. It is recommended to install or replace it when the furnace is shut down.

II. Precautions for use

1. Regular inspection: During use, check the working status of the thermocouple regularly to observe whether there is damage, looseness, etc. If problems are found, deal with them in time to ensure the accuracy of the measurement results.

2. Avoid over-temperature use: There is a certain operating temperature range, exceeding this range may cause damage to the thermocouple. Therefore, during use, ensure that the thermocouple works within the allowable temperature range.

3. Keep clean: The surface of the thermocouple should be kept clean to avoid dust accumulation, scaling and other phenomena affecting the measurement results. If necessary, use a soft brush or compressed air for cleaning.

4. Follow the operating procedures: When using, follow the relevant operating procedures to ensure the correct use of the thermocouple. Avoid illegal operation that causes damage to the thermocouple.

5. Regular calibration: In order to ensure the accuracy of the measurement results, it is recommended to calibrate the furnace tube blade thermocouple regularly. The calibration cycle can be determined according to the actual use.

Correct installation and use of furnace tube blade thermocouples are of great significance to ensure temperature monitoring of high-temperature equipment. Following the above precautions can effectively extend the service life of the thermocouple and improve the accuracy of the measurement results.
