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.
Ceramic Fiber Thermocouple Sleeve
Ceramic fiber thermocouple sleeve is a protective sheath for thermocouples. It is a splash guard for thermocouples. It prolongs the life of immersion thermocouples. It is also safer to use.

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.
- Outer protective tube
- Thermode
- Outer paper tube
- High temperature cement
- Compensation wire
- U-shaped quartz tube
The working principle of the immersion thermocouple is to measure the temperature by combining two different metal conductors into a closed circuit.
