Platinum-rhodium is a traditional temperature measuring element with stable thermoelectric performance and strong oxidation resistance.Temperature sensor S B R type Platinum rhodium thermocouple long-term use temperature is 1600℃ and the short-term use temperature is 1800℃. The outer cover is made of 99 corundum, and the inner cover is made of high-purity platinum and rhodium alloy wire. As temperature measurement sensors, they are usually used together with temperature transmitters, regulators and display instruments to form a process control system for direct measurement or control of various production processes in the 0-1700℃ range of fluid, steam and gas medium and solid surface temperature.

Platinum rhodium thermocouple is precious metal thermocouple. The diameter of even wire is 0.5mm, the allowable deviation is -0.015mm, the nominal chemical composition of its positive pole is platinum rhodium alloy, which contains 30% rhodium, 70% platinum, negative pole platinum rhodium alloy, contains 6% rhodium, so Temperature sensor S B R type Platinum rhodium thermocouple is commonly known as double platinum rhodium thermocouple. The maximum long-term use temperature of the thermocouple is 1600℃ and the maximum short-term use temperature is 1800℃.
