Armor type and what is the difference between general type thermocouple

General thermocouple: ordinary thermocouples generally by the hot electrode, insulation pipe, casing protection and junction box parts, such as type and armoured thermocouple is the thermocouple wire, insulation material and metal protective casing combination after assembly, after stretching processing from a combination of a solid.

armoured thermocouple: armoured thermocouple sheathed in refers to the insulation material and metal protective casing like armor wrapped on the outside of the thermocouple wire. Armoured role is to protect the thermocouple wire, increase protective layer on the outside of the thermocouple, such as stainless steel tubes, mesh to prevent the corrosion of acid and alkaline environment.
