Displacer Level Switch : CLS9
Displacer Level Switches are manufactured by Cirrus Engineering and are designed for mounting from top of the Vessels with internal working, in long operating range. The Displacer acting as the sensing medium allows for a wide range of switching differential and field adjustable switching.
Displacer are available in S.S. or Polypropylene and with suspension cable. The sensing hollow displacer float is suspended from a spring & cable assembly. When the liquid comes in contacts with the displacer, a buoyancy force is produced which causes the effective weight of the displacer to change, in turn causing the spring assembly in switch enclosure to seek a new balance position, which moves the attraction sleeve into the field of the magnet. This principle gives a wide switching differential and also a desired Level switching point can be obtained by moving the displacer up or down on the suspension cable. Further advantage is its use in high-pressure applications as the displacer have thicker wall thickness than conventional floats. Switches are available with single / multiple displacers and with optional still guide pipe.
Application: Water, pump controlling, acids, condensate, edible oil, large liquid storage tanks, ETP, STP etc.
