◈ Features
• High load carrying capacity
• Environmental safety
• Vibration resistance
◈ Operating Principle
This level switches have a displacer, switch unit in which micro switch and magnetic are assembled.
The operation is based upon simple buoyancy.
Immersion of the displacers in the liquid results in buoyancy force change, which moves the attraction sleeve upward or daunward.
Simultaneously, the contact of micro switch is changed by magnetic force as the attraction sleeve is the field of magnet force.
This principle allows adjustment of the switching point up to 15mm by moving the switch unit position.
