Armored thermocouple (wear-resistant)
Product overview
The armored thermocouple has the advantages of slender, easy to bend, fast heat response time, vibration resistance, high temperature resistance, compression resistance and durability. It can be used as a direct temperature measurement or as an assembly, the inner core element of a thermocouple to replace the traditional porcelain bead string components. The products are especially suitable for installation of narrow, curved and fast response, miniaturized and special temperature measurement occasions between pipes. The product is suitable for safe and explosion-proof occasions, widely used in petroleum and chemical industry with a variety of production site of flammable and explosive gas, steam.
Structure principle
The armoured thermocouple is composed of temperature sensing element, armoured lead wire, junction box and fixed device of various uses. There are two specifications of single and double branches.
The armored thermocouple can be covered with various materials, which is filled with high density oxide insulator. It has strong anti pollution performance and excellent mechanical strength. It is suitable for installation in bad environment.
Working principle
The electrode of the armored thermocouple consists of two different materials of different conductors. When there is a temperature difference between the measuring end and the reference end, the thermal potential will be generated, and the working instrument will show the temperature value corresponding to the thermal potential.
