Rosemount 2120 Vibrating Level Switch. The 2120 is a popular choice for its simplicity, ease-of-use, and reliability, in high and low level alarm applications. 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 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. 8/16 mA ( ‘Off ‘/ ‘On ‘), Direct Load, PNP, Relay, or NAMUR switched output electronics (depending on version) Threaded process connection for side, top, or bottom mounting 2 off M20 conduit entries for supplied cable gland and blanking plug (cable not supplied) Easy selection of Dry ‘On ‘ or Wet ‘On ‘ Mode and Switching Delay Magnetic test point makes functional test easy
