Applications
The sensor is a displacer heavier than the liquid, which is suspended by a commpression spring.
When 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 equlibrium position.
When the spring retracts the attraction sleeve moves upward into the field of external magnet.
(Thus overcoming the force of the bias spring and actuating the switching element.)
This principle allows adjustment of the switching point by moving the displacer along the guide pipe.
