The Rosemount 2130 vibrating short fork level switch by Emerson Process Management is designed for (Safety Integrity Level) SIL 2 safety instrumented systems. It features built-in fault monitoring/self-checking diagnostics and is suited for high and low level alarms.
Following successful third-party evaluation the Rosemount 2130 has 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 almost maintenance free, vibration fork technology while ensuring compliance with associated IEC industry standards. With several output types with a Safe Failure Fraction (SFF) over 90%, the resulting FMEDA report shows SIL 2 suitability. As per IEC 61508 and IEC 61511, the documentation provides safety instrumentation engineers with the required failure data and with proof test recommendations.
Further functionality in the new version includes a low-density option suitable for liquids with a specific gravity down to 0.5 (500 kg/m3), a wide choice of electronic output options for use on their own, or as part of an analogue or digital plant monitoring network. The Rosemount 2130 is designed for use in extreme temperatures ranging from -70 to 260 °C and like other models in the Rosemount 2100 range, the model is available with 316L stainless steel as standard, ECTFE/PFA copolymer coated 316L stainless steel or corrosion resistant alloy C wet side as well as a choice of electronic output types and aluminium or stainless steel housing options.
