Guided Wave Radar Level Transmitters Feature Failure Modes

Emerson Process Management recently announced the availability of its Rosemount 5300 Guided Wave Radar (GWR) level transmitters for SIL 2 safety instrumented systems. Following successful third-party evaluation, the 5300 series now comes with the required Failure Modes, Effects and Diagnostic Analysis (FMEDA) report. As a result, companies in the oil & gas production, refining, petrochemical, chemical and power industries can benefit from the superior performance of Guided Wave Radar (GWR) technology while ensuring compliance with associated IEC industry standards.

The 5300 Series was evaluated, as per hardware assessment IEC 61508, by global organization Exida. The resulting FMEDA report, with Safe Failure Fraction (SFF) over 90%, shows SIL 2 suitability. As per IEC 61508 & IEC 61511 the documentation provides safety instrumentation engineers with the required failure data and with proof test recommendations. With a five-year-plus proof test interval, the proof test can be co-ordinated with plant turnaround, minimizing process interruption and reducing risk to personnel.

The Rosemount 5300 series is a 2-wire GWR for challenging level and interface measurements on liquids, slurries and solids. It leverages the company’s 30 years of proven radar expertise and is designed to improve plant profitability through superior reliability, state-of-the-art safety features, effortless handling and unlimited connectivity.
