Application of Platinum Rhodium Thermocouple:
Also known as high-temperature precious metal thermocouple, platinum rhodium has single platinum rhodium (platinum rhodium 10 - platinum rhodium) and double platinum rhodium (platinum rhodium 30 - platinum rhodium 6). As temperature measurement sensors, they are usually used with temperature transmitters, regulators, and display instruments to form process control systems, used to directly measure or control the temperature of fluids, steam, gas media, and solid surfaces within the range of 0-1800 in various production processes.
Platinum rhodium thermocouple is a precious metal thermocouple. The thermocouple wire diameter is specified as 0.5mm, with allowable deviation -0.015mm. The nominal chemical composition of the positive electrode is platinum rhodium alloy, containing rhodium 30, platinum 70, and the negative electrode is platinum rhodium alloy, containing rhodium 6, so it is commonly called double platinum rhodium thermocouple. The long-term maximum operating temperature of this thermocouple is 1600, and the short-term maximum operating temperature is 1800.
Advantages of Platinum Rhodium Thermocouple
Platinum rhodium thermocouple has the highest accuracy, stability, wide temperature measurement range, long service life, and high upper temperature limit among thermocouple series. It is suitable for oxidizing and inert atmospheres, and can also be used in vacuum for short periods, but not suitable for reducing atmospheres or atmospheres containing metal or non-metal vapors. An obvious advantage of B-type thermocouple is that it does not require compensation wires for compensation, because the thermoelectric potential is less than 3μV in the range of 050.
