Product details
Platinum rhodium thermocouple is also called high temperature precious metal thermocouple. Platinum rhodium can be divided into single platinum rhodium (Platinum Rhodium 10 platinum rhodium) and double platinum rhodium (platinum rhodium 30 platinum rhodium 6). As temperature measuring sensors, they are usually used together with temperature transmitters, regulators and display instruments to form a process control system to directly measure or control the fluid, steam and gas within the range of 0-1700 ℃ in various production processes Body medium and solid surface.

Advantages of platinum rhodium thermocouple
Platinum rhodium thermocouples have the advantages of the highest accuracy, the best stability, wide temperature measurement range, long service life, high temperature upper limit, etc. It can be used in oxidizing and inert gases, or in vacuum for a short time, but not in reducing gases or gases containing metal or non-metal vapor. An obvious advantage of B-type thermocouple is that it does not need compensation wire, because the thermal potential is less than 3 μ V in the range of 0 ~ 50 ℃.
Selection of platinum rhodium thermocouple: it is recommended to use single platinum rhodium thermocouple (Platinum Rhodium 10 platinum) when the measured temperature is normal at 1000-1300 ℃, and double platinum rhodium thermocouple (platinum rhodium 30 platinum rhodium 6) when the measured temperature is normal at 1200-1600 ℃, so as to ensure the service life of platinum rhodium thermocouple within the temperature range used.
