Level switch now rated for SIL applications

The Rosemount 2120 level switch from Emerson Process Management is now certified for SIL 2 functional safety with SIL 3 capability, enabling the device to meet the most demanding safety application requirements. Emerson has also expanded the choice of process connections for greater installation flexibility. For safety critical applications, SIL 2 certification is now available for the 2120 with NAMUR and 8/16mA electronic outputs. There are five plug-in electronic outputs available providing a choice of switching functions. The SIL 2 certification extends the time between proof tests and allows users to avoid extra shutdowns for safety testing.
