WRP-131 Platinum Rhodium Thermocouple L=1000Application fields:

Rhodium is 10%, platinum is 90%, and the negative electrode (SN) is pure platinum, known as a single platinum rhodium thermocouple. The thermocouple * Z has a high operating temperature of 1300 ℃ and a short-term high operating temperature of 1600 ℃. Chemical machinery equipment, pipeline equipment, electric heating equipment, motor equipment, boiler smelting equipment, plastic processing equipment, steel manufacturing equipment, metal product equipment, coal-fired steam boiler equipment, aluminum manufacturing equipment, chemical machinery equipment, glass manufacturing equipment

Platinum rhodium 10 platinum thermocouple (S-type thermocouple) is a precious metal thermocouple. The diameter of the thermocouple wire is specified as 0.5mm, with an allowable deviation of -0.015mm. The nominal chemical composition of its positive electrode (SP) is platinum rhodium alloy, and 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 its excellent comprehensive performance and compatibility with temperature scales, the S-type thermocouple has 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 that S-type thermocouples can still be used to approximate temperature scales.
The shortcomings of S-type thermocouples are thermoelectric potential, low thermoelectric potential, low sensitivity, decreased mechanical strength at high temperatures, high sensitivity to pollution, expensive precious metal materials, and therefore a large one-time investment

WRP-131 Platinum Rhodium Thermocouple L=1000Application

Applied to various high-temperature situations in production processes, widely used for temperature measurement in glass and ceramics, industrial salt bath furnaces, etc.

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 thermoelectric heating of a platinum rhodium thermocouple will increase with the temperature at the measuring end, and its size is only related to the thermocouple material and the temperature at both ends, and is independent of the length and diameter of the thermoelectric electrode.
