Non-intrusive temperature instrumentation

Published:  27 April, 2017

Emerson Automation Solutions reports it has introduced a new platform for its RosemountX-wellTechnology surface sensing temperature measurement solution and says the X-well Technology with a Rosemount 3144P transmitter takes its place alongside the original WirelessHART X-well Technology to extend this non-intrusive temperature sensing technology for users in conventional wired I/O environments.

The company says this new product expands potential application possibilities for X-well Technology in plants and facilities where wired networks are already installed, or where WirelessHART has not yet been deployed. Other users have reportedly found X-well to be a useful replacement for difficult thermowell installations, which often have a wired connection already available and can be reused with the wired version of X-well.

X-well 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 to produce an accurate process temperature measurement.

The company says a major advantage of this technology is accurate process temperature measurement without requiring any intrusions or penetrations into the process, allowing for quicker and easier 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.

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