How to obtain accurate temperature values for platinum rhodium S-type thermocouples

Platinum rhodium S-type thermocouple: Ordinary thermocouples are usually composed of hot electrodes, insulation tubes, protective sleeves, and junction boxes. Platinum rhodium S-type thermocouples are a soft combination of thermocouple wires, insulation materials, and metal protective sleeves that are combined and processed by stretching.

Platinum rhodium S-type thermocouple: Armor in armored thermocouples refers to the insulation material and metal protective sleeve wrapped around the surface of the thermocouple wire like armor.

The effect of armor is to protect the thermocouple wire by adding a protective layer inside the thermocouple, such as stainless steel pipes, mesh, etc., to prevent corrosion under acidic, alkaline, and other conditions.
