Tips: How to prevent interference for thermocouple?

1. Isolation
   Isolation method is to hang thermocouple in the air to isolate thermocouple from refractory brick of furnace wall, and thermocouple is also isolated from support by use of insulation object. The method can prevent interference of high temperature electric leakage.
2. Shielding
   Shielding method is to make extension wire of thermocouple pass through iron tube or other metal shields to isolate. In this way, it can prevent electromagnetic interference and interference of high voltage electric field. When using this method, iron tube and shields should be connected with the ground well and twist the extension wire as well.
   
3. Ground connection
   This method has two forms: The first is to connect the reference end of thermocouple with the ground, and second is to connect the measurement end of thermocouple with the ground.
