Basic Principle
The Scanjet Macron operated type float level switch consists of a displacer, switch unit with micro switch and magnet.

The operation is based on simple buoyancy.

Immersion of the displacers in the liquid results in buoyancy force change, which moves the attraction sleeve upwards or downwards.

Simultaneously, the contact of micro switch is changed by magnetic force as the attraction sleeve is in the field of magnetic point force.

This principle allows adjustment of the switching point up to 15 mm by moving the switch unit position

Application
Displacement type float level switches are widely used for HFO storage and settling tanks, MDO, sludge tanks, fresh water tanks, lube oil tanks and others for high level overfill alarms.
