Rosemount 2120 Series Fork Level Switch Vibrating Level Switch, Side, Top Mount, ATEX-Rated, Non-Asbestos Carbon Fibre,

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
