FLOW SWITCH　KP-4/810/820/830,KPG-840  
Most suitable for detecting a flow on a conveyor!
[KP-4]
  • Intended for installation on the wall surface
  • Only urethane rubber is used as the material of the sensing plate.

[KP-810]
  • Most suitable for detecting a flow on places where robustness is required such as coal, crushed stone, mineral ore, and so on.
  • As the shaft is protected by a spring, the meter has a structure resistant to overloads.
    [KP-820]
  • As torque can be adjusted freely, the meter can be used for a low specific gravity.
  • Materials (SUS, rubber) and size of the sensing plate can be selected freely.

[KP-830]
  • Most suitable for detecting a falling substance in a tilt chute.
  • The L dimension can be selected freely.

[KPG-840]
  • It has a pressure-proof and explosion-proof structure and can be used in places where combustible dust such as coal is produced and dangerous places where a combustible gas is present.
  • A magnet coupling method is used for the switch and the sensing unit. The seal bellows prevent malfunctions due to dust adhesion.

operating principles

A measured substance carried by a conveyor pushes the sensing plate of the flow switch, and the internal cam mechanism activates the micro switch to make contact output.
When the measured substance passes over, the restraint of the sensing plate is released and the sensing plate goes back into position by its own weight and spring force. Then, the contact output is released.
