High-Concentration Dust Monitor

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

Monitor dust concentrations in high-density environments where conventional dust monitors cannot operate. Continuous measurement in g/m³-level dust zones provides the data needed to understand process conditions and make informed operational decisions.

Identify abnormal increases in dust concentration before they develop into serious incidents. Real-time monitoring and configurable alarms help support dust explosion prevention, fire risk management, and safer plant operations.

Replace routine inspection rounds with 24/7 automated dust monitoring. Continuous surveillance reduces operator workload, improves maintenance efficiency, and enables faster response to changing process conditions.

Provides 24H continuous measurement which is highly correlated with the absolute measurement (isokinetic sampling method) at a reasonable cost.

Utilizing a proven triboelectric sensing principle, the monitor delivers stable and reliable dust concentration measurement even in high-density dust environments.

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.

The High-Concentration Dust Monitor continuously samples process air, measures variations in dust concentration, and converts the data into analog and alarm outputs. This enables real-time monitoring of high-dust environments, helping operators detect abnormal conditions early, improve process visibility, and enhance operational safety.

1. Air Sampling
   The sensor unit continuously draws dust-laden air through its inlet using an integrated aspiration mechanism.
2. Dust Detection
   The sampled dust is measured by the detector, which continuously monitors changes in dust concentration within the airflow.
3. Signal Processing
   Measurement data is transmitted to the control unit, where it is converted into a proportional analog output signal for process monitoring and control applications.
4. Alarm Output
   When the measured dust concentration exceeds a user-defined threshold, the system activates an alarm contact output, enabling early warning and rapid response to abnormal conditions.
