Emerson has acquired Massachusetts-based IntelliSAW Inc., a  provider of systems that protect electric power transmission and distribution equipment by measuring and monitoring temperature, humidity and partial discharge using advanced sensor and analytic technologies. Terms of the acquisition were not disclosed.

“Continuous, reliable power is essential to our customers’ businesses, with outages potentially costing millions of dollars of lost production per day,” said Tom Moser, group vice president for Emerson Process Management’s measurement and analytical technologies. “Continuous and passive wireless monitoring allows users to safely monitor the health of critical power assets to avoid unplanned downtime, allowing for increased uptime and revenue generation.”

The IntelliSAW product line will become part of Emerson’s Rosemount portfolio of measurement and analytical technologies, which includes Pervasive Sensing applications that give customers a more complete view of their operations and facilities. Emerson says the acquisition strengthens customers’ ability to make better business decisions about their electric distribution systems.

IntelliSAW wireless monitoring capabilities consist of SAW-based temperature sensing, RF-based partial discharge detection, and humidity monitoring instruments along with an advanced human-machine interface. A suite of software tools is designed to seamlessly integrate the information into the user’s asset management infrastructure, including standard historians and alarm systems.
