Emerson Rosemount 5300 Guided Wave Radar (GWR) level transmitters

Emerson’s Rosemount 5300 Guided Wave Radar (GWR) level transmitters are certified to IEC 61508 for safety instrumented functions up to SIL 3. Companies in the oil and gas production, refining, petrochemical, chemical and power industries can benefit from the accuracy and flexibility of the series for safety-critical level applications such as overfill prevention and dry pump protection.

Traditionally, fixed point-level devices have been used for overfill prevention and dry pump protection. The series provides all the benefits of continuous level measurement, including the actual product surface location - confirming that the level sensor is functioning correctly. The high- and low-level alarms are set up locally or remotely during the installation and configuration process.

Proof testing is required at regular intervals to confirm that the overfill and empty tank protection functions result in the desired system response. These conditions can be simulated either locally using a HART-compliant master or remotely using Emerson’s AMS Suite software. By removing the need to perform traditional wet tests, which require the tank to be under- or overfilled, the cost and risks associated with proof testing are reduced.

The series is a two-wire GWR for challenging level and interface measurements on liquids, slurries and solids. The Direct Switch Technology (DST) function increases measurement reliability and capability. In addition to improving the signal-to-noise ratio, DST enhances the ability to handle disturbing factors, longer measuring ranges and lower dielectrics, even with a single probe. Maintenance-free operation improves uptime, and advanced configuration and extensive diagnostic information is available through the RadarMaster and EDDL-based user interface.
