protective cap for thermocouple

Steel or Aluminum Protective Cap

Thermocouple protection caps are also called slag caps. It is used to protect the U-shaped quartz tube through the molten metal slag layer and enter the molten metal layer. Different outer protection tubes should be selected according to the temperature of the metal liquid to be measured.

Thermocouple with Paper Tube

Thermocouple paper tubes are thermally insulated and insulated. The paper tube of the fast thermocouple will also be different according to the specific conditions of the use site. The length is 300mm, 500mm, 600mm, 800mm, 1000mm, 1200mm, and other specifications.

The length of the paper tube can be customized according to your requirements.

This FAQ part is for more information on thermocouples. Keep reading to learn more. Select SEFU to be your reliable supplier.

What is a Molten Metal Thermocouple?

Thermocouples that can be immersed directly in molten metal. Molten metal will melt the thermocouple wire, so it can only be detected for a short time. This type of thermocouple should only be used where even a small amount of melting of the thermocouple wire will not cause problems.

What is the Structure of Molten Metal Thermocouples?
  • Outer protective tube
  • Thermode
  • Outer paper tube
  • High temperature cement
  • Compensation wire
  • U-shaped quartz tube
What is the working principle of thermocouple?

The working principle of the immersion thermocouple is to measure the temperature by combining two different metal conductors into a closed circuit.
