Why Level switch and how its use

  • Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface.
  • Substances that flow become essentially horizontal in their containers (or other  physical boundaries) because of gravity whereas most bulk solids pile at an angle of  repose to a peak.
  • The substance to be measured can be inside a container or can be in its natural form
  • Level Switches are sensors with an electrical contact output at a specific liquid,  powder or bulk level.
  • Capacitive, conductive, diaphragm, displacer, float, inductive, optical,paddle,vibrating  rod, tilt, and tuning fork models are the different types of level switches available.
  • The level measurement can be either continuous or point values. Continuous level  sensors measure level within a specified range and determine the exact amount of  substance in a certain place, while point-level sensors only indicate whether the  substance is above or below the sensing point.
