Rosemount 2140 Level Switch

The Rosemount 2140 is a vibrating fork level switch for applications including overfill prevention, high and low level alarms, and pump protection. Utilizing the wired HART® protocol, the 2140 can be easily integrated into automated systems without the need for additional wiring. Switch easily between HART 5 and HART 7 to further meet requirements. Providing reliable level detection of all liquids as well as sediments, the Rosemount 2140 offers greater ease-of-use and flexibility with smart diagnostics that continuously monitor electronic and mechanical device health, and a fully integrated remote proof-testing capability, helping to increase safety and efficiency of both plant and workers. The Rosemount 2140:SIS is certified to IEC 61508 (SIL 2) for safety-critical applications.
