WRNM-230 Wear resistant Thermocouple Specification and Model

Introduction to the Temperature Measurement Principle of Wear resistant Thermocouples Thermocouples Thermocouples have the advantages of simple structure, high measurement accuracy, small bare wire heat capacity, and good interchangeability of materials. Thermocouple thermometers using thermocouples as sensors have a temperature measurement range of up to K for low temperatures and up to 00c for high temperatures. Thermocouples can perform multi-point temperature measurements, and their output signals can be transmitted over long distances Easy to detect and control. Therefore, thermocouples have been widely used in industrial production and research. The thermoelectric effect connects two different conductors or semiconductors into a closed circuit, as shown in the figure. If their two contacts are placed at different temperatures, an electric potential will be generated in the circuit. This phenomenon is called the thermoelectric effect Also known as Seebeck effect. The generated electric potential is commonly referred to as thermoelectric potential, denoted as EABT, To. The orifice flowmeter thermocouple is the sensitive element of the thermocouple thermometer, and its basic principle of temperature measurement is based on the thermoelectric effect. As shown in the figure, two different conductors or semiconductors A and B are connected into a closed circuit. When the temperatures of the two contacts are different, such as TT, a thermoelectric potential EAsT, T0 will be generated in the circuit. Conductors A and B are called thermoelectric poles, where A represents the positive pole of the thermocouple. B represents the negative electrode. The combination of two hot electrodes A and B is called a thermocouple. In two contact points Contact point is the process of welding two electrodes together and placing them in the object being measured to feel its temperature. Therefore, it is called the measuring end, hot end, or working end.

Introduction to the Temperature Measurement Principle of Wear resistant Thermocouples in Power Plants

Due to the use of different high-strength wear-resistant protective tubes and surface modification measures for different temperature ranges and tested media, this series of products forms a composite tube type solid structure. It is suitable for temperature measurement of flowing powders and materials such as petrochemicals, coal transportation systems, fluidized bed boilers, cement mature materials, and refractory materials with severe wear of protective tubes. Further improve the service life of thermocouples. Its performance is superior to current wear-resistant thermocouples and has won high praise from users. With multiple high-tech products at the highest level, its special wear-resistant material technology completely solves the service life of temperature measurement thermocouples in circulating fluidized bed boilers without affecting temperature hysteresis. The protective sleeve has many technologies such as wear resistance, high temperature oxidation resistance, sulfur resistance, corrosion resistance of liquid iron powder, limestone and other cement materials, erosion resistance, and vibration resistance, making the service life of temperature measurement thermocouples generally one to two years.
