◊ Displacement Type Float Level Switch
|
◈ Features
• Wide
differential
• Fully
sealed
• Easy
maintenance
• Durable
float
• Unaffected
by liquid agitation.
◈ Application
Displacement type float level switches are widely
used for coaltar fuel oil tanks, heavy fuel oil tanks,
setting tanks, sludge tanks, sewage tanks, fresh
water tanks, lube oil tanks, D.O, tanks, bilge well
and others. |
◈ Operating
Principle
This level switch consists of compression spring, displacer
and switch unit in which micro switch and magnetic are assembled.
The operation is based upon simple buoyancy whereby a spring
is loaded with weighted displacer which are heavier than the liquid.
Immersion of the displacers in the liquid results in buoyancy
force change, which moves the spring upward. simultaneously, the spring
is retracted of extended and attraction sleeve moves upward into the field
of external magnet in the switch unit.
The contact of micro switch is changed by magnetic force as
the attraction sleeve is in
the field of magnet point force.
This principle allows adjustment of the switching point by
moving the displacer along the guide pipe.
