Case Study: Sensor Testing and Validation for Improved Tubeskin Thermocouple Accuracy during Next Turnaround
Adam DeLancey | Applications, TemperatureAn energy company suspected that some of the tubeskin thermocouples in their process units weren’t accurate, but they didn’t know which ones were off. WIKA’s R&D Testing Center in Houston pinpointed the culprits and advised the customer on which sensor and …
Case Study: WIKA Equips Syngas Plant with Long-Lasting Thermocouples
Alina Green | Applications, TemperatureAt a Texas-based syngas plant, the thermocouples in its partial oxidation units were lasting an average of three months before failing. But after switching to WIKA’s TC84 platinum thermocouple with sapphire protection tube, the facility has not had to replace its …
Partial Oxidation (POX) Reactions Pose Challenges for Thermocouples and Other Measuring Instruments
Alina Green | Applications, TemperatureThe extreme temperatures and high concentration of hydrogen in partial oxidation (POX) reactors create a harsh environment for measuring instruments that are not equipped to handle such challenges. Partial oxidation (POX), the initial process of turning crude …
Pyrometer or Surface Thermocouples: Which Is Better for Tube Wall Temperature Monitoring?
Alina Green | Know-how, TemperatureOperators of steam methane reformers have various methods at their disposal for measuring tube wall temperature, but the best solution for accurate and continuous temperature measurement are surface thermocouples. The furnace tubes of a steam methane reformer (SMR) …
