The working principle of the platinum rhodium thermocouple

Platinum-rhodium thermocouple is made up of two different components on both sides of the conductor answered the synthesis loop, when the two junction temperature is not at the same time, will be hot current in circuit. If the work end of the thermocouple with the reference when there is a difference in temperature, display instrument will be installed a thermocouple temperature of thermoelectric power corresponds to occur. Platinum rhodium thermocouple electric hot will grows with the temperature measuring end, the size of the platinum rhodium thermocouple only related to the materials and the temperature on both sides of the thermocouple, and has nothing to do with the hot electrode length and diameter. Various platinum-rhodium thermocouple appearance often due to the actual need to appearance, but they are roughly the same basic structure, usually by the hot electrode, insulation sleeve protecting tube and the junction box and other main ingredients.
