Rosemount 2120 Product Data Sheet Reliable Performance...In Challenging Applications MEASUREMENT PRINCIPLE The Rosemount 2120 is designed using the principle of a tuning fork. A piezo-electric crystal oscillates the forks at their natural frequency. Changes to this frequency are continuously monitored. The frequency of the vibrating fork sensor changes depending on the medium in which it is immersed. The denser the liquid, the lower the frequency. When used as a low level alarm, the liquid in the tank or pipe drains down past the fork, causing a change of natural frequency that is detected by the electronics and switches the output state. When the 2120 is used as a high level alarm, the liquid rises in the tank or pipe, making contact with the fork which then causes the output state to switch. Threaded Process Connection Flanged Process Connection Adjustable Switching Delay KEY FEATURES AND BENEFITS Virtually unaffected by turbulence, foam, vibration, solids content, coating, or liquid properties The 2120 is designed for operation in temperatures from 40 to 02 F ( 40 to 150 C) DIBt/WHG overfill protection certification Electronic self-checking and condition monitoring. The heartbeat LED gives status and health information on the 2120 Adjustable switching delay prevents false switching in turbulent or splashing applications Fast Drip fork design gives quicker response time, especially with viscous liquids Rapid wet-to-dry time for highly responsive switching Fork shape is optimized for hand polishing to meet hygienic requirements No moving parts or crevices for virtually no maintenance Fast Drip Forks 2

Product Data Sheet Rosemount 2120 Fit and Forget Once installed, the 2120 is ready to go. It needs no calibration and requires minimum installation The heartbeat LED gives an instant visual indication that the unit is operational Functional testing of the instrument and system is easy with a magnetic test point You can install, and forget it Superior Performance The 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, making the 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 level alarms Pump control or limit detection Run dry or pump protection Hygienic applications High temperature applications Wireless applications High And Low Level Alarm High Temperature Applications Pump Control / Limit Detection Wireless Applications
