Rosemount 5408 radar level transmitter

At a time when experienced personnel are retiring and processes are being run closer to their capacity, Emerson Automation Solutions has launched a 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 an intuitive software interface guide the operator through installation, commissioning, proof-testing, operation and maintenance. Enhanced onboard diagnostics support preventive 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.

The Rosemount 5408 uses two-wire frequency modulated continuous wave (FMCW) technology that uses a continuous echo to maximise 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 that can cause signal disturbance, improving measurement accuracy and reliability.

To further enhance measurement reliability, an 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.
