WRN-532 thermocouple, As a sensor for measuring temperature, industrial assembled thermocouples are usually used in conjunction with display instruments, recording instruments and electronic regulators. It can directly measure the surface temperature of liquid, steam and gas media and solids in the range of 0℃～1800℃ in various production processes. According to national regulations, our factory has been producing platinum rhodium 30-platinum rhodium 6, platinum rhodium 10-platinum, nickel-chromium-nickel silicon, nickel-chromium-copper-nickel, copper-copper-nickel, which meet the IEC international standard index number, since 1987. , Iron-copper-nickel and other types of thermocouples should meet the JB/T3238-1999 standard. Working principle: The working principle of the thermocouple is: the two ends of the conductor of different components are welded to form a loop, the direct temperature measurement terminal is called the measurement terminal, and the terminal terminal is called the reference terminal. When there is a temperature difference between the measuring terminal and the reference terminal, a thermal current will be generated in the loop. Connect the display meter, and the meter will indicate the thermocouple and the corresponding temperature value of the thermoelectromotive force generated. The thermoelectromotive force of the thermocouple will increase as the temperature of the measuring terminal increases. The magnitude of the thermoelectromotive force is only related to the thermocouple conductor material and the temperature difference between the two ends, and has nothing to do with the length and diameter of the thermoelectrode. The assembled thermocouple is mainly composed of a junction box, a protection tube, an insulating sleeve, a connection terminal, and a thermoelectrode. It is also composed of various installation fixtures.
