Internal structure of cartridge heater with thermocouple

In the cartridge heater, a cartridge heater with a thermocouple is bred in the hope of detecting the temperature at certain points. Carridge heater with a thermocouple is used to detect temperature by adding a K or J thermocouple into it, but the position of the thermocouple is different, so the temperature position of the thermocouple is different.

1. bottom grounding type

The thermocouple is placed at the bottom of the tube and communicated with the shell of the electric heating tube. Because the temperature measuring node at the bottom can be in close contact with the mold, the temperature sensing speed is fast, and the process structure is suitable for all sizes of electric heat pipe.

2. pipe bottom non grounding type
The temperature sensing speed is slower than the contact structure at the bottom of the tube, and is often used as reference temperature.

3. tube intermediate grounding type
It is suitable for measuring the inner temperature of an electric heating pipe with a length of more than 80 mm, and plays an over-temperature monitoring role.

4. tube intermediate non grounding type

It is suitable for measuring the temperature of the inner wall of the shell of the electric heat pipe, which is longer than 80 mm. It is widely used as a reference for the temperature of the shell of the electric heat pipe.
