Accuracy and Response Times for Thermocouples, Thermowells and Other Temperature Instruments for Syngas Plants
| Robert Torgerson | Know-howEach temperature measurement system on the market has its particular features and limitations. When deciding which ones to use in syngas plant reactors, it is important to take into account the response times, accuracy, and other specifications of thermocouples, …
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
| Adam DeLancey | 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 …
