Upcoming Product Launch:
High-Concentration Dust Monitor

Bringing Visibility to Previously Unmeasurable High-Concentration Zones (g/m³)

Provides continuous dust concentration measurement even in high-concentration environments beyond the capabilities of conventional dust monitors.

ABOUT

Most conventional dust monitors are intended for measurements in the mg/m³ range.

The high-concentration dust monitor is designed for reliable operation in extreme dust environments, where concentrations reach the g/m³ level.

By visualizing dust concentration even in dust-laden processes, it helps improve risk assessment, safety management, and operational control.

Intended Applications / Operating Environments

• Conveying processes for wood pellets and biomass fuels
• Dust-laden environments in powder conveying and storage processes
• Sites requiring strict management of dust explosion and fire risks

CHALLENGES

Measures to mitigate dust explosion and fire risks are increasingly required.

Conventional methods are unable to measure and monitor high dust concentrations.

Reduce the workload associated with routine inspection rounds

SOLUTION

Provides 24-Hours 7-Days monitoring of high-concentration dust environments.

By visualizing dust concentration levels and enabling alarm management through configurable threshold settings, it delivers continuous and reliable oversight.

Early detection of abnormal trends helps reduce the risk of dust explosions and fires, while also minimizing operational workload and inspection burden.

FEATURES

When dust particles transported inside the duct contact or pass near the sensing probe, frictional electrostatic charge (triboelectric charge) is generated.

The amount of charge transfer is measured and converted into a relative dust concentration proportional to the actual concentration.

Anomalies are indicated through analog outputs and alarm contact signals.

Incorporating a dust-guiding duct and fan, the design remains simple and user-friendly.

It is carefully engineered to ensure stable and reliable measurement even in high-concentration dust environments.

• Maximum measurable concentration: 165 g/m³
  (Note: Measurement capability varies depending on the type of powder.)
• Measurement ranges: 9 selectable ranges
• Alarm outputs: 2 alarm relay contacts (user-configurable)
• Power supply: AC 100 / 200 V supported

Linearity of detected concentration has been verified using test powder (talc).

The sensor is installed in a location separated from areas where large amounts of dust are generated.

Dust is drawn in and measured using a built-in self-suction mechanism.

After measurement, the dust is returned to its original location and is not discharged externally, minimizing impact on the surrounding operating environment.
