• 要約等: <p>This study describes a real-time measurement method for detecting potentially explosive concentration of wood pellet dust. The method uses image analysis for Gaussian beam extinction to overcome limitations of conventional methods such as filter-based collection, electrostatic detection, and optical scattering, struggling to quantify high dust concentrations with real-time monitoring. We modeled the extinction and intensity distribution of Gaussian beams and validated the approach through experiments using dust suspensions. CMOS camera-based image analysis enables selective detection of beam extinction, minimizing noise from forward scattering, diffraction, and ambient light. The results show a linear relationship between the beam image area and dust concentration, demonstrating superior detectability until potentially explosive region and a broader measurable range compared to photodiode methods. The proposed method offers a promising solution for stable, real-time monitoring of dust concentrations near the lower explosive limit, contributing to improved safety and process control in industrial settings.</p>
