The use of the platinum-rhodium thermocouple temperature

The use of the platinum-rhodium thermocouple temperature was minus 200~1300℃。 Platinum rhodium thermocouple has advantages of good linearity, thermoelectric emfs, high sensitivity, stability and uniformity is good, strong antioxidant properties, low price and is not affected by short-range ordering etc, and its performance is better than that of K type thermocouple, thermocouple is a kind of very promising. N type thermocouple cannot be directly used in sulfur at high temperature, reducing or restore, alternating oxidation atmosphere and vacuum. So can't use EN and TN to replace. Iron - Constantan thermocouple measuring temperature area for - 200 ~ 1200 ℃, but usually use temperature range of 0 ~ 750 ℃ J type thermocouple has advantages of good linearity, thermoelectric emfs is larger, higher sensitivity, stability and uniformity is good, the advantages of cheap, widely used by users. Platinum rhodium thermocouple can be used in a vacuum, oxidation, reduction and inert atmosphere, but the positive iron oxidation at high temperature quickly, so the temperature is restricted, cannot directly without reserve used in curing atmosphere at high temperature. Platinum rhodium thermocouple containing rhodium (10%), containing platinum was 90%, the cathode ( SN) For pure platinum, commonly known as single platinum-rhodium thermocouple. The thermocouple * long-term high temperature of 1300 ℃, short-term * high temperature of 1600 ℃. S type thermocouple in the series of thermocouple with high accuracy *, * good stability, test your area wide, long service life, etc. Its physical and chemical properties, good stability of thermoelectric potential and good antioxidant properties at high temperatures, applicable in oxidizing and inert atmosphere. Due to platinum rhodium thermocouple with excellent comprehensive properties, in line with international use scale platinum-rhodium thermocouple, long as international temperature scale interpolation apparatus.
