The Rosemount 2511 Solids Level Switch uses the principle of a tuning fork and a piezo-electric crystal to oscillate the forks at their natural frequency. Changes to the oscillation frequency are continuously monitored by electronics which varies depending on whether the fork is covered or uncovered by a solids medium. Ideal for use with fine-grained and powdered materials and suitable for hygienic applications - forks are made from stainless steel.
The Rosemount 2511 is available as a standard fork length and tube/cable extended fork lengths with short extension lengths are able to withstand high mechanical loads such as low-level indication in very large or tall silos. Its short fork design allows mounting in small pipes or process vessels with very limited space, giving it versatile installation- may be installed in vertical, horizontal, or angled positions.
