Improving Vacuum Tower Yield and Product Quality Through Advanced Temperature Measurement
Robert Torgerson | Know-howVacuum tower revamps and internal upgrades can improve the yield and product quality of vacuum distillation units (VDU), a must in today's competitive markets. These modifications, though, require a considerable influx of capital. Improvements in cross sectional tower …
4-Wire RTDs vs. 3-Wire RTDs
Adam DeLancey | Know-how, TemperatureThe electrical resistance of some materials, such as platinum, copper, and nickel, differs at different temperatures. Resistance temperature detectors (RTDs) take advantage of this property to assess temperature in a variety of commercial and industrial applications. …
