Refinery 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 …
From Extreme Heat to Arctic Cold: WIKA’s Replaceable Thermocouple and RTD Temperature Sensor
Adam DeLancey | TemperatureWhen reactors or pipelines are located in extremely hot or cold conditions, they must be insulated in order to keep the process media within an optimal temperature range. This insulation, however, makes it time-consuming and expensive for operators to replace a …
The Role of Thermocouple Sensors in Catalyst Die-Off Predictions for LTS Syngas Reactors
Robert Torgerson | Know-howBy using thermocouple sensors and plotting temperature measurements at different points in the catalyst bed, syngas plant operators can accurately predict catalyst behavior. The resulting “S” curves – along with shifts and shape changes over time – also give …
Prevent Hydrocracking Runaways with the Gayesco Flex-R® Multipoint Thermocouple
Robert Torgerson | TemperatureThermal runaways in hydrocracking processes are a serious concern for refiners. Comprehensive, real-time temperature monitoring is critical to preventing runaways, which is why most hydrocrackers across the world are equipped with Gayesco Flex-R ® multipoint …
