VIPL-DLS-05 Displacer Type Level Switch

The displacer level switch is designed for internal mounting through the top of process vessel and is also furnished withchamber for external mounting from the process vessel. The use of displacer as the sensing medium allows for wide switchingDifferential, field adjustable switching point & use on high pressure applications. Mounting connection without chamber isoffered in 3" flanged standard.Principle of OperationDisplacer operated level switch offer control featured not found in float operated controls. TheBasic sensing means utilizes displacer Heavier than the liquid which is suspended from a spring.When the liquid contacts the displacer to change in turn causing the spring to seek a new bala-nce position which moves the attraction sleeve into the field of the magnet. This PrincipleProvides for wide switching differential and allows the desired level switching point to beAdjusted by moving the displacers up and down the suspension cable. Further advantageAllow for adoption to high pressure application since displacers have substantial heavierWall thickness than floats and in many cases are made out of solid materials.
