Situation of the use of the platinum-rhodium thermocouple temperature

Platinum-rhodium thermocouple of the physical and chemical properties are relatively good, and the steady performance of the thermoelectric potential, such as oxidation resistance and high temperature conditions are relatively good, so is suitable for use in a inert and oxidizing atmosphere.

under normal circumstances the use of the platinum-rhodium thermocouple temperature should be guaranteed in - 200 - Between 1300 ℃ and the advantages of platinum-rhodium thermocouple is also very much, such as better linearity, sensitivity is very high, thermoelectric emfs is bigger, antioxidant performance is stronger, uniformity and stability is better, but the price is cheap, the main is not affected by the outside world other. So on the comprehensive performance is better than the k type thermocouple, belongs to a new thermocouple product development premise unusually good, because of you, type thermocouple can not be directly for the use of sulfur in the heat, as well as the reducibility and reduction, such as oxidation of alternating atmosphere or vacuum can not be used. Because of platinum-rhodium thermocouple has higher comprehensive performance, and platinum rhodium thermocouple is very accord with international temperature scale related to use standard, in a long time before, once the international temperature scale interpolation instrument for use, is well received by the high and widely in the industry. Actually platinum-rhodium thermocouple information, small make up before an introduction has been a lot of, if you still have what not understand, can be directly login our company website to understand.
