Rosemount™ 2120 Level Switch – Vibrating Fork

Rosemount™ 2120 Level Switch - Vibrating Fork

The Rosemount 2120 Level Switch provides easy to install, reliable level detection and control. 3rd party IEC61508 (SIL2) safety and hygienic certification with choice of outputs makes it suitable for a wide range of applications. It has no moving parts, needs no calibration and is virtually unaffected by process conditions. Adjustable switching delay prevents false switching in turbulent applications. Understand what is going on with your process- the visible heartbeat LED provides device status and health, and magnetic test point provides an easy-to-use functional test.

  • Key Features

Key Features

  • Reliable point level detection: provides accurate high and low level switching with no moving parts and no calibration required, ensuring reliable performance across applications
  • Unaffected by challenging process conditions: performs reliably despite flow, bubbles, turbulence, foam, vibration, coating, or liquid property variations
  • SIL2 certified for safety critical applications: independently tested to IEC 61508 for safety integrity, supporting overfill protection and pump protection strategies
  • Fast response in viscous liquids: “fast drip” fork design shortens reaction time for quicker switching in demanding or sticky media
  • Prevents false switching: adjustable switching delay helps avoid nuisance triggers in turbulent or splashing conditions
  • Simple health and status monitoring: heartbeat LED provides visible indication of device status, with electronic self checking for easy diagnostics
  • Easy functional testing: magnetic test point enables fast, safe verification of switch operation without process interruption
  • Hygienic approvals available: certified to 3 A, EHEDG, FDA, and ASME BPE requirements for sanitary applications (where selected)
  • Optional 12 VDC solar or battery operation: can be powered by solar or battery sources using the 12 VDC version for remote or off grid installations
