Product Detail

Flow Switch KP-4/810/820/830/840


Most suitable for detecting a flow on a conveyor!

  • Intended for installation on the wall surface.(KP-4)
  • Most suitable for detecting a flow on places where robustness is required such as coal, crushed stone, mineral ore, and so on.(KP-810)
  • As torque can be adjusted freely, the meter can be used for a low specific gravity.(KP-820)
  • Most suitable for detecting a falling substance in a tilt chute.(KP-830)
  • Powder
  • Granules
  • Lump

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.
