| Robert TorgersonGayesco-WIKA has decades of expertise in designing, manufacturing, and installing high-performance temperature measurement systems for refineries, an industry that requires accurate and robust thermocouple assemblies to keep their applications running smoothly and …
Grain Growth in Type K Thermocouples: Some Causes and Solutions
| Robert TorgersonExtremely 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 DeLanceyGreen 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 …
Using Temperature Measurement to Monitor Performance and Startup in Steam Methane Reformers
| Robert TorgersonTo produce hydrogen for industrial use, syngas (synthesis gas) plants all over the world use steam methane reformers (SMR). Temperature measurement and monitoring is key to performance and safety, especially during the potentially dangerous startup process. A steam …
