WRP-130 thermocoupleCommonly known as S-type thermocouple, this product is carefully designed and manufactured by our company and complies with the new generation series of products of the Electrotechnical Commission (IEC) standards. It is matched with display instruments and has long-term application in the temperature range of 0-1300 ℃. This series of products has reliable technology, performance, long service life, and can replace foreign and domestic temperature sensors of the same level. It is also suitable for the maintenance and replacement of imported complete sets of equipment or the complete matching of output projects, as well as the matching of technical transformation projects.

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. Due to reliable material selection, the sensors produced by our company have never encountered quality problems in industries such as chemical, petrochemical, power, metallurgy, etc. due to substandard protective tube materials. The WRP-130 thermocouple uses domestically produced materials and accessories from Kunming Guiyan Platinum Industry Co., Ltd; The entire product undergoes strict metrological verification before leaving the factory, ensuring that all products meet national metrological requirements. Therefore, the strict internal quality of thermocouples fully meets the requirements of the user unitWRP-130 thermocoupleFor precious metal thermocouples. The WRP-130 thermocouple has a long-term maximum operating temperature of 1300 ℃ and a short-term maximum operating temperature of 1600 ℃. The S-type thermocouple has the advantages of high accuracy, stability, wide temperature measurement range, and long service life in the thermocouple series. It has good physical and chemical properties, stable thermoelectric potential, and excellent oxidation resistance at high temperatures, making it suitable for both oxidizing and inert atmospheres.

Due to the excellent comprehensive performance of the WRP-130 thermocouple, which is suitable for S-type thermocouples using temperature scales, it has long been used as an interpolation instrument for temperature scales. Although "ITS-90" stipulates that it will no longer be used as an internal inspection instrument for temperature scales in the future, the Temperature Advisory Committee (CCT) believes thatWRP-130 thermocoupleIt can still be used to approximate temperature scales. The shortcomings of WRP-130 thermocouple are thermoelectric potential, low thermoelectric potential, low sensitivity reading, decreased mechanical strength at high temperatures, high sensitivity to pollution, expensive precious metal materials, and therefore a large one-time investment. The working principle of WRP-130 thermocouple is that platinum rhodium thermocouple is composed of two conductors with different compositions connected at both ends to form a circuit. When the temperature of the two junction points is different, a thermal current will be generated in the circuit. If there is a temperature difference between the working end and the reference end of the thermocouple, the display instrument will indicate the temperature value corresponding to the thermoelectric potential generated by the thermocouple.

The WRP-130 thermocouple uses high-purity platinum as the negative electrode and platinum rhodium alloy as the positive electrode, and is used in powder metallurgy, sintering bright furnaces, vacuum furnaces, smelting furnaces, and various refractory materials. The outer tube material is corundum, and the measurement temperature is 0-1800 degrees. WRP-130 thermocouple is a traditional temperature measuring element with stable thermoelectric performance and strong oxidation resistance. It is suitable for continuous use in oxidizing and inert atmospheres, with a long-term use temperature of 1600 ℃ and a short-term use temperature of 1800 ℃. The WRP-130 thermocouple has the highest accuracy, stability, wide temperature measurement range, long service life, and high temperature measurement upper limit in the thermocouple series.WRP-130 thermocoupleSuitable for oxidizing and inert atmospheres, and can also be used in vacuum for a short period of time, but not suitable for reducing atmospheres or atmospheres containing metal or non-metal vapors. A significant advantage of B-type thermocouples is that they do not require compensation wires, as the thermoelectric potential is less than 3 μ within the range of 0-50 ℃.
