Dust Monitor

Liên hệ

A dust monitor is a dust indicator (dust concentration meter) that monitors dust generation from a dust collector.

Brand: Matsushima
Origin: Japan


  1. 24-hour monitoring ensures that even the slightest leak is not overlooked.
  2. Eliminates sudden dust leaks, reducing the burden of periodic inspections. Contributes to labor saving.
  3. You can use up the filter to the end. This leads to a reduction in maintenance costs.


  • Monitors 24 hours a day on behalf of people and does not miss even the slightest leaks.
  • Dust meter conforming to JIS standards

Operating principle

Attach the Dust Monitor to the secondary side piping of the dust collector.
When the dust leaked into the exhaust gas contacts or passes near the probe of the Dust Monitor, charge transfer (tribo) occurs. The amount of charge transfer is detected as a relative concentration proportional to the dust concentration, and this is analog output and an alarm contact informs you of an abnormality.

How to use?

  1. Determine the mounting position:

    The flow velocity in the duct should be 4 m/sec or more, and please install it on a straight body that has a rectifying effect. Avoid bends, extreme narrowing, or near fans, as the airflow will be turbulent and the measurement will be unstable.
  2. Mounting:

    Weld the included 1 inch socket into the perforated duct, insert the probe and screw it in. Be sure to connect the ground.
  3. Wiring:

    Wire to the power supply, analog output, and contact output. (The image is an integrated dust monitor.) Use a dedicated cable to connect the separate/high temperature/explosion proof sensor and the converter.
  4. Adjustment:

    Carry out the adjustment when the flow velocity is constant and the filter is normal. Normally, set the range selector switch within the range of 1 to 9. Set the integration time as necessary.
