And the characteristics of platinum-rhodium thermocouple

by:JVTIA     2020-11-08
Platinum rhodium thermocouple performance and characteristics of the platinum rhodium thermocouple is also called high temperature thermocouple, precious metals platinum rhodium have single platinum rhodium ( Platinum rhodium - 10 Platinum rhodium) And double platinum rhodium ( Platinum rhodium - 30 Platinum rhodium (6) , them as temperature measurement sensor, usually with temperature transmitter, controller and display instrument, such as process control system, to directly measure or control in the production of a variety of 0 Fluid over a range of 1800 ℃, steam and gas medium and solid surface temperature. Platinum rhodium thermocouple is composed of two different components of the conductor when two ends synthesis loop, when the two junction temperature is not at the same time, 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 electric hot will grows with the temperature measuring end, it is only with the size of the thermocouple temperature at the ends of the materials and relevant, has nothing to do with the hot electrode length and diameter. The appearance of various platinum-rhodium thermocouple often because of the need to vary, but they are roughly the same, the basic structure of the usually by hot electrode, insulation sleeve to protect the main components such as pipe and connection box. Advantages: platinum rhodium thermocouple in the thermocouple series has high accuracy *, * good stability, test your area wide, long service life, high temperature limit, etc. Suitable for oxidation and inert atmosphere, can also be short term used in vacuum, but does not apply to 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.
