Dust Monitoring Equipment
DUST MONITOR

Online dust indicator for dust collector
 

Dust Monitor is a dust indicator (dust concentration meter) that monitors dust generation from a dust collector.

24-hour continuous monitoring of minute amounts of dust leakage from dust collectors.

It quickly detects the beginning of dust leakage and notifies you.

Advantages

  1. 24-hour monitoring ensures that even the slightest leak is not overlooked. Achieve predictive maintenance .
     
  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 .

Features of Dust Monitor

Powder measuring instrument Dust Monitor adopts the triboelectric (electric charge) method. Its main features are:

Monitors 24 hours a day
on behalf of people and
does not miss even the
slightest leaks.

Continuous measurement (0.1 to 1000mg/㎥) on behalf of humans.

We will notify you before the dust exceeds the regulation value. The filter can be used up to the end, realizing eco-conservation.

Dust meter conforming to JIS standards

An automatic dust concentration measuring instrument based on the performance evaluation method (JIS B7996). There is a strong correlation with the manual analysis method (JIS Z 8808) with a correlation coefficient of 0.969.


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
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.

*For details, please refer to the instruction manual.

Maintenance

If you use it for a long time, you may be concerned about the soundness of the Dust Monitor.

We offer a design that considers after installation and a service that considers long-term reliability.

To remove the sensor,
just remove one bolt


When removing the sensor, the probe can be easily pulled out simply by loosening the bolt attached to the boss. It saves you the trouble of removing the cable.

POINT!

Assuming that the probe will be pulled out, wire the cable with a margin.

To clean, just wipe the
probe with a waste cloth

For cleaning, simply wipe off dirt from the probe with a slightly damp cloth. If there is no dust leakage, it will not get dirty, so it is recommended to clean it when the equipment is stopped.

POINT!

If you clean the probe as it is, it will short circuit the board, so turn off the power, wear insulated gloves, and work with the ground connected.

If you are concerned
about whether the device is normal, check with the soundness check service

If you are unsure if your Dust Monitor is working properly, please use our health check calibration and adjustment service.

POINT!

Our service personnel can visit the site or send the main unit to our factory for confirmation.
