Corrosion sensors join Rosemount wireless instrument arsenal

Technology allows process piping to be continuously monitored for integrity.

Emerson has added non-intrusive wireless corrosion monitoring to its Pervasive Sensing strategies portfolio, continuing its strategy to invest in its core business platforms and expand in markets that hold significant long-term growth opportunity.

On Oct. 3, 2016, Emerson announced it had agreed to acquire U.K.-based Permasense Ltd., a leading provider of non-intrusive corrosion monitoring technologies for the offshore and onshore oil production, refining, chemical, power, pipelines, metals and mining and other industries. Permasense monitoring systems use non-intrusive ultrasonic wall thickness measurement sensor technology, wireless data delivery and advanced analytics to continuously monitor for metal loss from corrosion or erosion in pipes, pipelines or vessels.

The Permasense product line will become part of Emerson’s Rosemount portfolio of measurement and analytical technologies. Permasense technologies complement Emerson’s Roxar intrusive corrosion monitoring and non-intrusive sand management systems, and strengthen the company’s Pervasive Sensing applications. With Permasense and Roxar technologies in its portfolio, Emerson will be the largest provider of integrity and corrosion management solutions in the marketplace.

Central to Permasense corrosion monitoring systems are sensors that employ proven ultrasonic wall thickness measurement principles. The sensors are battery powered and communicate wirelessly, eliminating the cable, minimizing the cost of installation, and enabling use in remote areas and on a large scale with thousands of sensors. The sensors’ low-power consumption enables deployment in Zone 0-rated, intrinsically safe areas of the plant.

A browser-based data analysis and visualization software, DataManager, enables the wall thickness data to be accessed anywhere in the world via an Internet connection, facilitating automated collection and management of integrity data from the most remote, even unmanned, facilities.
