Green rot thermocouple
WebOct 4, 2024 · While chromel in Type K thermocouples can be prone to developing “green rot” in vacuum or reduced oxygen environments with higher temperatures, Type N thermocouples can deliver accurate readings in these settings. Another advantage of Type N thermocouples is that they are better suited for nuclear environments, making them a … WebGreen Rot Green-Rot is most pronounced when the thermocouples are used between 815°C to 1040°C (1500°F to 1900°F). ln order to avoid this problem, large lD protection tubes should be used to maximize internal air circulation or the installation of an oxygen getter in the bottom of the protection tube. lf Green-Rot is a serious problem, Type ...
