The Rosemount 2140:SIS is IEC 61508 (SIL 2) certified for mission critical applications.

Specifications
Operating pressure: from full vacuum to 1450 psig at 122 °F (100 bar at 50 °C)
Operating temperature: -40 to 302 °F (-40 to 150 °C) as standard. -94 to 500 °F (-70 to 260 °C) as an option
Certificates/approvals: ATEX, IECEx, USA, Canada, see technical data for full list of certifications.
Safety: IEC 61508 SIL 2 certified
Diagnostics: Continuous electronic self-monitoring and condition monitoring.

The Rosemount™ 2140 is the world's first wired level transmitter with a HART® tuning fork for applications such as overfill prevention, high and low level alarms, and pump protection. Providing reliable level detection for all liquids as well as sludge, the Rosemount 2140 is easy to use and flexible with intelligent diagnostics that continuously monitor the status of electronic and mechanical devices, and a fully integrated remote testing feature that helps improve the safety and efficiency of both equipment and workers.

The Rosemount 2120 level switch provides easy installation and reliable level detection and control. IEC61508 (SIL2) and third-party hygienic certification and selectable output signals make it suitable for a wide range of applications. It has no moving parts, requires no calibration and is virtually unaffected by process conditions. The adjustable switching delay prevents false switching in turbulent conditions. Understand what's happening with your process - a visible heartbeat indicator shows device status and performance, and a magnetic test point provides an easy-to-use functional test.
