Rosemount X-well Technology non-intrusive temperature measurement

Click2Contact

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. It provides process temperature measurement while eliminating possible leak points and simplifying installation and maintenance.

The product is available via the Rosemount 648 wireless temperature transmitter and Rosemount 0085 pipe clamp sensor assembly, working 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.

An advantage of the technology is process temperature measurement without requiring any intrusions or penetrations into the process, allowing for quick and easy installation along with simplified long-term maintenance. Users do not have to design, size or maintain thermowells. Wake frequency calculations are eliminated, as well as time spent determining material compatibility, the right insertion length and the necessary profile.

With Rosemount X-well Technology, users can add temperature measurement points without having to shut down a process. The technology can be installed with a standard pipe clamp procedure and ordinary hand tools and does not require a skilled contractor.

Applications that can benefit from the technology include pipelines, high-velocity flows, slurries, heavy particulate fluids, wellheads, clean-in-place processes, high-viscosity fluids and harsh processes in the oil and gas, chemical, refining, food and beverage, metals and mining, and pulp and paper industries.
