Switch Overview
The Rosemount 2110 is a liquid point level switch based on the vibrating short fork
technology. It is a compact switch with a rugged stainless steel body and forks for use in a
wide range of liquid applications. Economical

-in. or 1-in. threaded mounting in pipes or
tanks or hygienic mounting for food industry use. Direct load switching suits all supplies or
PNP output for direct interface to PLCs. For use in safe area only.
Short Fork Technology
The natural frequency (~1300Hz) of the fork is chosen to avoid interference from plant
vibration which may cause false switching. This also gives short fork length for minimal
intrusion into vessel and pipe. Using Short Fork Technology, the Rosemount 2110 is
designed for use in virtually all liquid applications. Extensive research has maximized the
operational effectiveness of the fork design making it suitable for almost all liquids, including
coating liquids (avoid bridging of forks), aerated liquids, and slurries.
Rosemount 2110 Application and Mounting Examples
For most liquids including coating and aerated liquids and slurries, the function is virtually
unaffected by flow, turbulence, bubbles, foam, vibration, solid particles, build-up or
properties of the liquid.
For use in safe area and process temperatures up to 302°F (150°C).
Mount in any position in the tank or pipe. Mounting is by
