Rosemount 5300 GWR level transmitters

Emerson Process Management’s Rosemount 5300 2-wire GWR level transmitters are now certified to IEC 61508 for safety instrumented functions up to SIL3. Companies in the oil and gas production, refining, petrochemical, chemical and power industries can use the level transmitters for safety-critical level applications such as overfill prevention and dry-pump protection.

The functional safety assessment was performed by the independent global organisation exida. It covered SIL2-rated safety applications in a single configuration, and SIL3-rated safety applications in redundant mode. The certification means that the level transmitter is suitable for continuous level measurement in safety instrumented functions up to SIL3, as defined in IEC 61511 for applications in the process industry.

Traditionally, fixed-point-level devices have been used for overfill prevention and dry-pump protection. The Rosemount 5300 GWR 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, such as a Rosemount Radar Master or Field Communicator, or remotely using Emerson’s AMS Suite software.
