Product overview

The Rosemount 2120 vibrating fork level switch is a high-performance liquid level detection device designed based on advanced vibrating fork technology, specifically developed for point liquid level measurement and control requirements in industrial processes.

Main features and advantages
■ It is almost unaffected by flow rate, bubbles, turbulence, foam, vibration, solid content, coating, liquid properties and product changes.
■ Rosemount 2120 is designed to operate at temperatures ranging from -40 to 302°F (-40 to 150°C).
■ The "heartbeat type" LED indicates its working status. When the output of the switch is "OFF", the LED will flash. When the output is "ON", the LED remains on.
The adjustable switching delay function can prevent false switching in turbulent or splash applications.
The "fast dripping" type tuning fork design can improve the response speed, especially for viscous liquids.
The switching time Settings for wet-to-dry and dry-to-wet are short, enabling rapid response switching.
■ Manual polishing is used to optimize the shape of the tuning fork to meet hygiene requirements. Mechanical and electrolytic polishing options.
■ Magnetic test points make functional testing more convenient.
■ No moving parts or gaps, and almost no maintenance is required.
There are multiple plug-in electronic component options, each with adjustable modes and switching delays

Application example

The device integrates overflow protection to prevent tank leakage, eliminating environmental hazards and costly cleanup operations. Its dual high/low level alarms enhance process safety compliance.

Key functional innovations include:
1. Third-Pump Sequencing Controlwith position detection to optimize liquid mixing homogeneity and suppress false switching risks from splashing (tolerance <5% FS).
2. Dry-Run Protectioncombining cost-effective installation (0.75" NPT thread) with advanced pump protection logic (response time <0.5s).
3. WirelessHART Connectivity(IEC 62591 compliant) enabling remote diagnostics and SIL2-rated safety interlocks.
4. Sanitary Designfeaturing 3-A compliant polished surfaces (Ra ≤0.8μm) and CIP/SIP compatibility for hygienic industries.
Certified for hazardous areas (ATEX/IECEx Zone 0) and extreme conditions (-40°C to 150°C), this solution delivers 99.8% availability across petrochemical, pharmaceutical, and food & beverage applications.
