Rosemount 2120 level switch with SIL2 certification

Emerson Process Management has expanded the application scope for its Rosemount 2120 range of vibrating fork point liquid level switches. The switch is now certified for SIL2 functional safety with NAMUR and 8/16 mA electronic outputs.

There are five plug-in electronic outputs available, providing a choice of switching functions. The SIL2 certification extends the time between proof tests and allows users to avoid extra shutdowns for safety testing.

The range has been approved for marine applications, such as oil and ballast control and HFO blending by the American Bureau of Shipping (ABS).

The switch also offers an expanded choice of process connections. In addition to the 50.8 mm NPT process connection, the switch is available with Mobrey A and G flanges enabling compatibility with mechanical float switch process connections.

The switch is suitable for high- and low-level alarm and pump control duties in a range of process and marine applications.
