Description

 

Thiết Bị Đo Mức Model OLS

(Operated Type Float Level Switch)

 

Model : OLS
Manufacturer : SUN KOREA
Origin : KOREA



 

◈ 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.
