Features

  • Only for wall mount. (KP-4)
  • Suitable for detecting flow such as coal, crushed stone, mineral ore etc. which requires robustness. (KP-810)
  • Applicable to material with low specific gravity as torque is freely adjustable. (KP-820)
  • Suitable for detecting falling material in a tilt chute. (KP-830)

Operating Principles

Material carried by a conveyor pushes the sensing plate of the flow switch, and the internal cam activates the micro switch to output contact. When the material 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.
