Advanced Temperature Measurement and Control Insight of the Day

To maximize the temperature difference between the thermowell tip and the pipe or equipment wall (minimize thermal conduction error), decrease the thermal conductivity, increase the length of the thermowell, and decrease the diameter of the thermowell (increase thermal resistance between tip and pipe or equipment wall). Swaged or tapered thermowells maximize this temperature difference and …

Advanced Temperature Measurement and Control Insight of the Day

To minimize the temperature difference between the thermowell tip and the process, maximize the heat transfer coefficient by increasing the fluid velocity and eliminating process coatings and minimize the mass of the thermowell tip. To minimize the temperature difference between the thermowell tip and the sensing element tip, insure the sheath is seated firmly and …

CHARMED Upgrading UT Pickle Separations to DeltaV v11

The University of Texas Pickle Research Campus located in Austin, Texas is home to a unique experimental facility that is used to improve energy efficiency of fluid mixture separation processes and optimize the capital utilization of existing plants. The semi-works scale equipment is not only unique in size but also in the level of highly …

Advanced Temperature Measurement and Control Insight of the Day

Two single element RTD sensors instead of a dual element sensor provide a faster response with better diagnostics (such as drift) and less susceptibility to vibration and common mode failures. Three sensors and middle signal selection would inherently and automatically eliminate a single failure or accuracy problem of any type from affecting the selected temperature. …
