Grain Growth in Type K Thermocouples: Some Causes and Solutions
Robert Torgerson | TemperatureExtremely high temperatures over time lead to grain growth in type K thermocouples, which can cause metal separation and thermocouple failure. Fortunately, good solutions exist for minimizing the effect of grain growth. Grain growth is a common cause of failure in …
How Green Rot Affects Type K Thermocouples
Gabriel Gonzales | TemperatureGreen rot is most pronounced when type K thermocouples are exposed to temperatures between approximately 800°C and 1,260°C (1,472°F to 2,300°F) and when there’s a low concentration of oxygen. This problem causes negative drifts, inaccurate measurements, and even …
