Working principle of high temperature platinum rhodium thermocouple
task principle is platinum rhodium thermocouple is composed of two different components of two ends decomposition circuit conductor, when not together two junction temperature, thermal current in circuit. If the task end of the thermocouple and reference end when there is a difference in temperature, display instrument will indicate the thermocouple thermoelectric potential of the corresponding temperature value.
low temperature platinum-rhodium thermocouple choice: measuring the temperature of the normal during 1000 ~ 1300 ℃ proposed using single platinum-rhodium thermocouple ( Platinum rhodium - 10 Platinum) , measuring the temperature of the normal during 1200 ~ 1600 ℃ proposed using double platinum rhodium thermocouple ( Platinum rhodium - 30 Platinum rhodium (6) So in the use of talents to ensure that the use of the platinum-rhodium thermocouple temperature field life.
