Overview
The shortcomings of the Shuanghua high-temperature S-type single platinum rhodium thermocouple are its thermoelectric potential, low thermoelectric potential, low sensitivity, decreased mechanical strength at high temperatures, high sensitivity to pollution, and expensive precious metal materials, resulting in a large one-time investment. The S-type, also known as the single platinum rhodium thermocouple, has an S division mark and is mainly used to measure the temperature of the medium between 0 and 1600 ℃. It is a category of precious metal thermocouples. Normal use in high-temperature environments such as coking plants and steel mills.

S-type High Temperature Resistant Thermocouple
WRP-130
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, which contains 10% rhodium and 90% platinum. The negative electrode (SN) is pure platinum, hence it is commonly known as a single platinum rhodium thermocouple. The maximum long-term usage temperature of this thermocouple is 1300 ℃, and the maximum short-term usage temperature is 1600 ℃.
The S-type high-temperature resistant 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, the S-type high-temperature resistant thermocouple, which meets the requirements of using temperature scales, 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 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
