WRP-130 thermocoupleUsually used in conjunction with display instruments, recording instruments, electronic computers, etc. Directly measure the temperature of liquid, vapor, gas media, and solid surfaces within the range of 0 ℃ to 1300 ℃ in the presence of hydrocarbons and other explosives on the production site.

WRP-130 thermocouple has multiple explosion-proof forms, good explosion-proof performance, pressure spring type temperature sensing element, good anti vibration performance, large measurement range, high mechanical strength, and good pressure resistance. The WRP-130 thermocouple utilizes the principle of gap explosion-proof to design junction boxes and other components with sufficient strength. All components that can generate sparks, arcs, and dangerous temperatures are sealed inside the junction box cavity. When an explosion occurs inside the cavity, it can be extinguished and cooled through the gap between the joint surfaces, preventing the flame and temperature after the explosion from being transmitted outside the cavity, thus enabling temperature measurement.WRP-130 thermocoupleAs a temperature sensor, it is usually used in conjunction with display instruments, recording instruments, and electronic regulators. It can directly measure the surface temperature of liquids, vapors, gases, and solids within the range of 0 ℃ to 1800 ℃ in various production processes.

The WRP-130 thermocouple is mainly composed of a junction box, protective tube, insulating sleeve, terminal block, and thermoelectric electrode, and is equipped with various installation and fixing devices. The WRP-130 thermocouple is a circuit formed by welding two conductors with different compositions at both ends. The direct temperature measuring end is called the measuring end, and the wiring terminal end is called the reference end. When there is a temperature difference between the measuring end and the reference end, a thermal current will be generated in the circuit. When connected to the display instrument, the instrument will indicateWRP-130 thermocoupleThe corresponding temperature value of the thermoelectric potential generated. The thermoelectric potential of a thermocouple will increase as the temperature at the measuring end rises. The magnitude of the thermoelectric potential is only related to the material of the thermocouple conductor and the temperature difference between the two ends, and is independent of the length and diameter of the thermoelectric electrode.

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, iron copper nickel thermocouples and other types of thermocouples that comply with IEC standard division numbers since 1987. The high alumina or corundum ceramic protective tubes used in WRP-130 thermocouples have undergone strict material screening to ensure that all protective tube materials used comply with relevant national standards.WRP-130 thermocoupleUsed in industries such as chemical, petrochemical, power, metallurgy, etc., thermocouples have never undergone strict metrological verification before leaving the factory due to the protection of tube materials, ensuring that all products meet national metrological requirements. Therefore, the strict internal quality of thermocouples fully meets the temperature requirements of the user unit.
