A15/A10/B15/B10/C10/C15 Multi-point displacer switches

Magnetrol International

Displacer switches utilize buoyancy force acting on immersed displacers in the liquid to detect and convert liquid level changes to signal outputs.

Operating principle is based on buoyancy force acting on displacers hung on suspension cable connected with spring. Increase in buoyancy force acting on displacers immersed in the liquid causes spring compression which then moves magnetic sleeve into magnet field which activates switch mechanism. Magnetic sleeve moves inside the non-magnetic tube which isolates switch mechanism from measured medium. Built-in spring stroke limit stops prevent “false alarms” caused by sudden liquid level changes.

Depending on function available displacer switches can be divided into following types:

Switches with narrow differential destined for switch point levels:
- A15 – switch models with single switch for one switch point level
- B15 – switch models with two switches for two switch point levels
- C15 – switch models with three switches for three switch point levels
Switches with wide differential destined for pump controls and/or switch point levels:
- A10 – switch models with single switch for pump control
- B10 – switch models with two switches for two pump controls or one switch point level and one pump control
- C10 – switch models with three switches for three pump controls or one switch point level and two pump controls or two switch point levels and one pump control
