Gayesco Flex-O™ Multipoint Thermometer: Ideal for Temperature Monitoring in Reactor Pipewells
Robert Torgerson | TemperatureTechnicians need an accurate temperature profile of a reactor or fuel depot for safe, efficient operations. However, these high-temperature applications pose challenges for many temperature monitoring instruments. Multipoint thermometers also tend to be unwieldy, …
Multipoint Thermocouple Assemblies: Not Just for Fixed Bed Reactors
Robert Torgerson | ApplicationsRefineries rely on multipoint thermocouples to monitor temperature at different points inside fixed-bed reactors. However, these temperature measurement systems are also extremely useful for evaluating performance in fluid catalytic cracking (FCC) units, vapor …
The Problems with Verifying Thermocouple Accuracy During Reactor Startups
Robert Torgerson | Know-howRefinery operators who work with fixed bed catalysts place a high value on temperature accuracy, but they also don’t want to waste time by taking unnecessary temperature readings. Thus, to better understand any radial temperature differences that may exist during …
What to Know about Aging and Drift in Type K Thermocouples
Robert Torgerson | Know-how, TemperatureWith repeated exposure to high temperatures, a Type K thermocouple becomes less accurate. Aging is a phenomenon that results in higher-than-accurate temperature readings, while drift results in lower-than-accurate readings. While all Type K thermocouples experience …
