Working principle

WRN-0313T WRN2-0313T WRNK-0913T WRNK2-0913T Thermocouple on the top of the boiler is a kind of temperature measuring device suitable for boiler top of power plant and other occasions requiring remote and high-pressure temperature measurement. The electrode is composed of two different conductor materials. 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 display the temperature value corresponding to the thermal potential.

Working principle of WRN-0313T WRN2-0313T WRNK-0913T WRNK2-0913T Thermocouple on the top of the boiler

● two conductors kwith different components (called thermocouple wire or Thermoelectrode) are connected to form a circuit at both ends. When the temperature of the junction is different, electromotive force will be generated in the circuit. This phenomenon is called thermoelectric effect, and this electromotive force is called thermal electromotive force. Thermocouple uses this principle to measure temperature. In, one end directly used to measure medium temperature is called working end (also known as measuring end) and the other end is called cold end (also known as compensation end); The cold end is connected with the display instrument or supporting instrument, and the display instrument will indicate the thermoelectric potential generated by the thermocouple.
Thermocouple is actually an energy converter, which converts heat energy into electric energy. The generated thermoelectric potential measures the temperature. For the thermoelectric potential of thermocouple, the following problems should be paid attention to:
1: The thermoelectric potential of the thermocouple is the difference of the temperature function at both ends of the working end of the thermocouple, not the function of the temperature difference between the cold end and the working end of the thermocouple
2: the magnitude of the thermoelectric potential generated by the thermocouple, when the thermocouple material is uniform, has nothing to do with the length and diameter of the thermocouple, and is related to the composition of the thermocouple material and the temperature difference at both ends;

High stability and long service life. The Armored Core and the hole bottom of the outer protective tube are elastically compressed, with fast thermal response and strong seismic resistance. Open the cavity junction box to make the wiring convenient and reliable. The casing, thermocouple and thermal resistance are of split structure, which can quickly replace components without shutdown. The protective tube is made of high temperature resistant, anti-oxidation and wear-resistant materials. The integral protective tube processed by deep blind hole has the advantages of high pressure resistance, no fracture, reliable use and long service life
