The explosion-proof dust online monitoring system is primarily composed of a particulate matter measurement device, a sampling device, and a data acquisition and transmission unit. Integrated with monitoring platform software, it enables real-time online monitoring of particulate concentration in factory areas, comprehensive data analysis, threshold-exceeding alarms, and control system linkage. This system is widely applied in explosion-proof environments such as steel plants, coal powder silos, mines, ports and docks, sulfur warehouses, and chemical storage facilities.
Modular design with flexible configuration combinations, enabling customizable setup of different monitoring factors to suit various dust monitoring environments.
Equipped with an optically stable self-calibration device and online self-zeroing system, effectively eliminating long-term operational system errors. The system is traceable to national standard stations.
Enables online measurement of particles of varying sizes (e.g., PM1, PM2.5, PM10, PM100, TSP) via a metallic cutter without requiring replacement of the sampling cutter.
Incorporates dynamic heating dehumidification control with continuous humidity correction, significantly reducing environmental humidity’s impact on measurement accuracy.
Utilizes a long-lasting anti-interference sampling power system that operates quietly and efficiently, with adjustable sampling cycles.
Integrated wireless transmission module and RS485 interface, supporting data transmission via GPRS/CDMA, 3G/4G/5G public networks, or dedicated lines. Enables 24/7/365 uninterrupted data collection, remote control, parameter adjustment, and fault diagnosis.
Complies with explosion-proof requirements for Zone I and Zone II hazardous areas, ensuring safe and reliable operation.
Optional mounting poles and brackets for outdoor monitoring operations.
Seamless integration with environmental display LED screens at factory entrances, eliminating the need for additional screens.
Features sheath gas protection and reverse purge function for maintenance-free operation.
