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 …
Aging and Drift in Type K Thermocouples
| Robert Torgerson | Know-howWith 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 …
Use WIKA’s High Pressure Transmitter for Precise, Consistent Waterjet Cutting
| Patrick McGrath | PressureA pressure transmitter is essential for waterjet cutting, a highly effective and affordable method for slicing through a wide range of materials. WIKA’s HP-2 high pressure transducer enables high precision monitoring at pressures up to 15,000 bar (217,000 psi). A …
WIKA’s ScrutonWell® Reduces Vibration to Provide Accurate, Rapid Thermometer Response Time
| Adam DeLancey | TemperatureA thermowell is a protective housing for a thermometer used to provide temperature readings for an industrial process. Given that process media in many industries are corrosive, abrasive or under high pressure, a thermometer is placed inside a thermowell so the …
