Thermocouple WRN2-230 is a temperature measurement element whose working principle is based on the Seebeck effect. When two conductors of different compositions (such as nickel-chromium and nickel-silicon) are welded at both ends to form a loop, one end is the measuring end (hot end) and the other end is the reference end (cold end). When there is a temperature difference between the measuring end and the reference end, a thermoelectric potential will be generated in the loop. By connecting the display instrument, the thermoelectric potential can be converted into the corresponding temperature value. The thermoelectric potential of the thermocouple is related to the conductor material and the temperature difference between the two ends, but has nothing to do with the length and diameter of the thermoelectrode.

Thermocouple WRN2-230 is mainly composed of a junction box, a protective tube, an insulating sleeve, a terminal block and a thermoelectrode. It has a compact design and is easy to install and maintain. The protective tube is made of stainless steel and has good corrosion resistance and mechanical strength.

Thermocouple WRN2-230 is widely used in temperature measurement in industrial production processes, such as chemical, petroleum, electric power, metallurgy and other industries. It can measure the temperature of liquid, gas, steam and solid surface, and is suitable for a variety of harsh working environments.

Advantages of thermocouple WRN2-230

• Simple structure: easy to install and maintain.

• Wide temperature measurement range: can meet the temperature measurement needs of various industrial occasions.

• High accuracy: the measurement results are accurate and reliable.

• Small inertia: fast response speed, suitable for fast-changing temperature measurement.

• Convenient for remote transmission: the output signal is easy to transmit over long distances, which is convenient for centralized control.

When selecting, it is necessary to select the appropriate graduation number, measurement range and protection tube material according to the actual measurement needs. When installing, ensure that the insertion depth of the thermocouple is appropriate to ensure the accuracy of the measurement. At the same time, pay attention to the installation method and sealing of the protection tube to prevent external factors from affecting the measurement results.

Thermocouple WRN2-230 has become an indispensable tool in industrial temperature measurement with its excellent performance and wide range of applications.
