Application scope for vibrating fork level switch expanded

Sep 02 2014


Emerson Process Management has expanded the application scope for its patented Rosemount 2120 range of vibrating fork point liquid level switches.

This level switch is now certified for SIL 2 functional safety with SIL 3 capability enabling the device to meet the most demanding safety application requirements.

The 2120 range is now approved for marine applications by ABS and Emerson has also added an expanded 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.

The 2120 also offers an expanded choice of process connections. In addition to the new 2 inch NPT process connection, the switch is now available with Mobrey A and G flanges enabling compatibility with mechanical float switch process connections.

For marine applications, such as oil and ballast control and HFO blending, the 2120 is now approved by ABS – expanding on the existing GL approval.

The simplicity, ease of use and reliability of the Rosemount 2120 vibrating fork switch makes it a popular choice for high and low level alarm and pump control duties in wide range of process and marine applications, the company claimed.
