Emerson Introduces Safety-Certified Non-Contacting Level Radar to Help Increase Plant Safety and Worker Efficiency

Easy-to-use SIL 3 device provides enhanced diagnostics and remote proof-testing capability, supporting critical overfill prevention applications

At a time when experienced personnel are retiring and processes are being run closer to their capacity, Emerson Automation Solutions has launched a new non-contacting radar transmitter that helps operators increase reliability and safety. The SIL 3-capable Rosemount™ 5408 Non-Contacting Radar Level Transmitter uses enhanced technology and Human Centered Design to deliver accurate, reliable measurement and ease-of-use, supporting greater worker efficiency and plant safety.

To reduce complexity and enable less experienced workers to easily manage their level measurements for tank monitoring, process control and overfill prevention, the Rosemount 5408 has been designed to simplify operator tasks. Pictorial instructions and a highly intuitive software interface guide the operator through installation, commissioning, proof-testing, operation and maintenance. Enhanced on-board diagnostics support preventative maintenance, and provide actionable information, streamlining the troubleshooting process. The ability to perform proof-testing and site acceptance tests remotely saves time, increases worker efficiency and reduces the reliance on highly experienced staff.

“With a changing workforce demographic and increasing pressure to improve plant efficiency, companies require instrumentation that is extremely reliable and easy to implement and operate,” said Andreas Hessel, Rosemount strategic product manager, Emerson Automation Solutions. “The Rosemount 5408 takes level measurement a big step forward in both areas, offering the most advanced and simple-to-use radar available.”

With the need to run plants closer to capacity it is essential that instrumentation provides greater measurement accuracy and reliability, especially in critical overfill prevention applications. To support this, the Rosemount 5408 uses two-wire Frequency Modulated Continuous Wave (FMCW) technology that uses a continuous echo to maximize radar signal strength and produce a more robust and reliable measurement. In addition, radar-on-chip technology replaces a circuit board, thereby removing sources of EMC noise which cause signal disturbance,improving measurement accuracy and reliability.

To further enhance measurement reliability, a unique embedded power back-up removes vulnerability to intermittent power losses.

Supporting efforts to increase plant safety, the Rosemount 5408’s SIL 3 capability enables it to be seamlessly integrated into a safety instrumented system. ATEX and IECEx approvals allow installation in hazardous locations.
