THEORY & STRUCTURE

On-line installation, mechanical type flow switch, used for liquid or gas medium.Sturdy plastic, aluminum or stainless steel housing optional.A medium to promote the plunger spring to the set position by magnetic field in the reed switch output passive on-off signal.

 

GENERAL CHARACTERISTICS

  • Minimal pressure loss
  • Good repeatability, dirt-resistance
  • Mechanical and the electronic part completely isolated
  • With Set dial gauge and easy to set
  • LED display switch state
  • Uses no need set in the scene

    Big switch capacity

  • A variety of materials and voltage level selection

 

APPLICATIONS

The gas-liquid dual-purpose type, industrial automation / mechanical equipment / air compressor industrial refrigeration and air conditioning.
