Rosemount 2120 Vibrating Fork Liquid Level Switch

Rosemount 2120 Vibrating Fork Liquid Level Switch

Universal package to suit virtually all liquid applications

The Rosemount 2120 is based on vibrating short fork technology, making it suitable for virtually all liquid applications. Features include a complete range of process connections, wide choice of housing and wetted parts materials, five different switching functions, extended fork lengths, hazardous area, basic self-checking functionality, and overfill approvals. The 2120 can withstand temperatures up to 302 °F (150 °C) and pressures to 1450 psig (100 barg). This combination of features makes it configurable to almost all requirements.

The Rosemount 2120 has been TUV tested and approved for overfill protection according to the German DiBt/ WHG regulations. It is certified under safety devices for tanks and piping related to water pollution control.

Superior performance

. The Rosemount 2120 is a popular choice for high and low level alarm and pump control duties for its simplicity, ease of use, and reliability

. Functionality is virtually unaffected by flow, turbulence, bubbles, foam, or vibration

. The ‘Fast Drip’ design allows the liquid to be quickly drawn away from the fork tip when mounted horizontally, making the Rosemount 2120 quicker and more responsive in high density or viscous liquid applications

. With a user-selectable time delay feature, the risk of false switching is minimized in turbulent or splashing applications

Applications

. Overfill protection

. High and low point level alarms

. Pump control or limit detection

. Run dry or pump protection

. Hygienic applications

. High-temperature applications

. Wireless applications
