Precious metal armoured thermocouple mainly consists of precious metal casing, insulating materials, dipole wire materials.

The characteristics of precious metal armoured thermocouples can be summarised as follows:

(1) Corrosion resistance

(2) good stability of the thermal potential, long-term use of the thermal potential drift is small;

(3) The upper limit of the use temperature is high;

(4) Armoured thermocouple end is hermetically sealed, no residual gas inside

(5) High insulation resistance, precious metal armoured thermocouple at room temperature can reach more than 50MΩ;

(6) Product specifications, protection tube materials can be processed according to user requirements

(7) Easy to bend, good flexibility, simple installation

(8) Resistant to pressure and vibration;

(9) Short thermal response time; long service life
