The NDIR Online Monitoring System Explosion Proof is designed for early fire detection in industrial environments. The system utilizes an imported sampling pump to extract CO gas from coal mills or pulverized coal bins through a sampling probe. After sample gas pre-processing, the AG300 infrared CO analyzer performs precise detection of CO gas concentration. Any increase in CO concentration serves as an early fire alarm indicator, enabling the system to trigger appropriate alerts.
The AG3000EX complete equipment package consists of seven integrated components:
