High temperature wear-resistant Thermocouple RTD Sensor  WRN2-630 use special materials such as heat-resistant materials and wear-resistant alloy materials as the temperature measurement outer casing and wear-resistant head. Depending on the measured temperature, the selected wear-resistant protection tube material also varies. They are connected by flange or thread, and can be used for temperature measurement in the range of 0-1400 degrees Celsius for a long time. They are used in metallurgy, chemical engineering, cement plants, power plants, etc The fluidized bed boiler industry is an ideal temperature sensor for measuring high temperature and wear-resistant environments, with a lifespan of up to two years. The components include wear-resistant head, connecting rod, threaded connection or flange, junction box, and armored inner core. The wear-resistant head should be selected based on the actual temperature at the production site, and the connecting rod, threaded connection or flange should be selected based on the presence of corrosive media on site.

Measurement principle of High temperature wear-resistant Thermocouple RTD Sensor  WRN2-630

The electrodes of high-temperature wear-resistant thermocouples are composed of two different conductor materials. When there is a temperature difference between the measurement end and the reference end, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.

The thermoelectric electromotive force of a thermocouple will increase as the temperature at the measurement end increases. The size of the thermoelectric electromotive force is only related to the material of the thermocouple conductor and the temperature difference at both ends, and is related to the length and diameter of the thermoelectric electrode. Non assembled thermocouples mainly consist of a junction box, protective tube, insulation sleeve, wiring terminal, and thermoelectric electrode, and are equipped with various installation and fixing devices.

Applicable occasions of High temperature wear-resistant Thermocouple RTD Sensor  WRN2-630

The wear-resistant thermocouple is a wear-resistant protective tube made of plasma spray paint technology, high chromium cast iron and high temperature alloy. It is specially designed and manufactured for measuring occasions in high, medium and low temperature wear-resistant environments, and can be used in industrial sites such as circulating fluidized bed, fluidized bed furnace, cement Rotary kiln exhaust chamber, coal powder furnace, ball mill, etc.
