Armored thermocouple has to bend, high pressure, fast thermal response time and good endurance, armored thermocouple and thermocouple assembly as a sensor for measuring temperature, usually sheathed thermocouple and display instruments , Recording and supporting the use of electronic regulator, while armored thermocouple can also be fabricated as a thermocouple temperature sensing element. Thermocouples can be measured directly from a variety of production processes 0 ¡æ ~ 1100 ¡æ within the liquid, vapor and gases and the solid surface temperature¡£
