Displacer Type Level Switches

All controls have been designed using modular concept standard assemblies may be incorporated in a wide variety of arrangements to meet virtually any control application allowing maximum interchangeability of assemblies. SSIC unique engineering & manufacturing capability handles special process requirements promptly with-out long delays at an economical cost.


These switches have a displacer heavier than the liquid, which is suspended by a spring. When the liquid contacts the displacer, a buoyancy force is produced, which causes the effective weight of the displacer to change, this causes the spring to retract slightly to a new equilibrium position. When the spring retracts the attraction sleeve moves upward into the field of external 'u' magnet (thus overcoming the force of the bias spring & actuating the switching element).

  • Wide differential.
  • Low cost & easy maintenance.
  • Unaffected by liquid agitation.
  • External adjustment range.
  • Choice of switches - Micro Switch / Mercury Switch / Reed Switch.

For wide switching differentials & higher pressure ratings. Used where traditional float operated units cannot work.
