Emerson Process Management has extended the capability of its Rosemount 2100 series of vibrating short fork level switches with the introduction of the Rosemount 2130 for (Safety Integrity Level) SIL 2 safety instrumented systems. This new version features built-in fault monitoring/self-checking diagnostics and is ideal for high and low level alarms.

Following successful 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 and-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 be coordinated with plant turnaround, minimizing process interruption and reducing risk to personnel.

The 2130 requires no on-site calibration, and the visible "heart-beat" LED gives an instant visual indication that 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.
