The advantages of platinum-rhodium thermocouple

Platinum rhodium thermocouple in the thermocouple series has high accuracy *, * good stability, test your area wide, long service life, high temperature limit, etc. Applicable in oxidizing and inert atmosphere, also can use short-term in a vacuum, but is not applicable in reducing atmosphere or containing metal or nonmetal steam atmosphere. B type thermocouple is an obvious advantage don't need a compensation for the compensation conductor, because in the range of 0 ~ 50 ℃ and internal potential less than 3 mu V. Disadvantages: platinum rhodium thermocouple deficiency is thermoelectric potential, thermoelectric potential rate is small, low sensitive to read, mechanical strength under high temperature to drop, is sensitive to pollution, expensive, precious metals and one-time investment. The working principle of platinum-rhodium thermocouple is platinum rhodium thermocouple is composed of two different components of two ends synthesis loop conductor, not at the same time, when the two junction temperature will produce thermal current in the circuit. If the work end of the thermocouple with the reference when there is a difference in temperature, display instrument will be installed by the thermocouple thermoelectric potential of the corresponding temperature value. Platinum rhodium thermocouple choice: measuring the temperature of the normal during 1000 ~ 1300 ℃ suggest using single platinum-rhodium thermocouple ( Platinum rhodium - 10 Platinum) , measuring the temperature of the normal during 1200 ~ 1600 ℃ suggest using double platinum rhodium thermocouple ( Platinum rhodium - 30 Platinum rhodium (6) So are using temperature range can ensure the service life of platinum-rhodium thermocouple.
