Emerson Surface-sensing temperature measurement
Rosemount X-well Technology is a surface-sensing temperature measurement solution that eliminates the need for thermowell process penetration when measuring process temperatures in pipe applications. This solution provides an accurate and repeatable internal process temperature measurement, while eliminating possible leak points and simplifying specification, installation and maintenance. It is available in the Rosemount 648 wireless temperature transmitter and Rosemount 0085 pipe clamp sensor assembly. These components work together to calculate process temperature via the transmitter’s thermal conductivity algorithm. The technology works by measuring the pipe surface temperature and ambient temperature and combining this information with an understanding of the thermal conductivity properties of the installation and process piping.
