Example Of Installation

Precaution For Installation

  • Check the voltage of the power supply. The built-in small motor requires a predetermined voltage which cannot be adjusted.
  • Carefully review places to be selected for installation-The wings should not come into contact with parts such as steel piers in silos or tanks -Avoid places where powder drops. Upper limit switches should be installed vertically to have the device exert its performance.
  • When the switch has been installed outdoors, problems may easily occur in electric piping in particular. If the level switch is lower than the wiring duct as shown in the figure, rainwater many flows into the electric piping and into the main body of the level switch in rainy seasons. Therefore, please pay special attention to this matter.
  • The level switch is mechanical and has a small built-in synchronous motor(torque: 0.1-1kgf/cm). Therefore, please be careful so that no foreign matter or impurities would go into the level switch while being installed.
  • If the pressure is applied to the diaphragm surface by powder in the silo or tank, the built-in micro-switch will operate due to the force. If there is no powder in the silo or tank, the switch will be automatically restored by the force of the built-in spring. When necessary, the internal spring’s force may be adjusted to adjust the sensitivity.
  • caution does not use this switch in use environments where the rubber diaphragm may be damaged.
