The SFDS is a continuous measurement analyzer system for monitoring carbon monoxide and oxygen in applications with high dust content. The extractive measurement of the components CO and O2 enables early detection of smoldering fires and timely initiation of fire-fighting measures. The ATEX-certified system components allow for reliable monitoring in dust Ex areas (ATEX zones 20, 21 and 22). Unlike with optical systems that measure the surface, deeper-lying embers can also be detected.
• Early detection of smoldering fires
• Early CO detection through continuous monitoring
• Application-specific gas sampling with integrated backflush
• Measurement point switchover for up to four sampling points
• Gas sampling using heated sample gas line for ATEX zones 21/22, gas sampling unit for zones 20/21/22
• Setup of analyzer cabinet in Ex-free areas
• Pre-configured complete system for easy commissioning
