Emerson Process Management introduced the Rosemount 2130 for (Safety Integrity Level) SIL 2 safety instrumented systems. This new version features built-in fault monitoring/self-checking diagnostics and works with high and low level alarms.
After gaining third-party evaluation by global organization exida, 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. With a five-year-plus proof test interval, the proof test can co-ordinate with plant turnaround, minimizing process interruption and reducing risk to personnel.
The new 2130 version is simple and easy-to-use, reliable in a wide range of applications and requires no on-site calibration. The visible “heart-beat” LED gives an instant visual indication the unit is operational. In addition, the built-in fault monitoring/self diagnostics can detect extreme corrosion of the forks, or any other internal or external damage to the fork sensor, which triggers a warning LED and safe handling of the load.
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 analog or digital plant monitoring network.
The Rosemount 2130 works in extreme temperatures ranging from -70 to + 260 °C (-94 to +500°F) and like other models in the Rosemount 2100 range, the new 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 aluminum or stainless steel housing options.
