Emerson Process Management, a leader in automation technology and services, has expanded the application scope for its Rosemount 2120 range of vibrating fork point liquid level switches.

Based in Missouri (US), Emerson helps businesses automate their production, processing and distribution in the chemical, oil and gas, refining, pulp and paper, power, water and wastewater treatment, mining and metals, food and beverage, life sciences and other industries.
 
The Rosemount 2120 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 the American Bureau of Shipping (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" NPT process connection, the switch is now available with Mobrey A and G flanges enabling compatibility with mechanical float switch process connections, said the US-based company.

For marine applications such as oil and ballast control and HFO blending, the 2120 is now approved by the American Bureau of Shipping (ABS) – expanding on the existing Germanischer (GL) approval, it stated.

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 statement added.-TradeArabia News Service
