Description

The SFDS is a continuous measurement 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 21 and 22, optionally in zone 20). Unlike with optical systems that measure the surface, deeper-lying embers can also be detected.

Field of application
  • Early detection of smoldering fires


Device properties:

  • 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 and also gas sampling unit for ATEX zones 21/22 (gas sampling from zone 20 is possible upon request)
  • Setup of analyzer cabinet in Ex-free areas
  • Pre-configured complete system for easy commissioning
Benefits
  • Risk minimization thanks to early detection of smoldering fires – protects your capital equipment
  • Long system uptime thanks to high gas sampling quality due to integrated backflush
  • Uninterrupted gas sampling possible in ATEX zones 21 and 22 (gas sampling from Zone 20 is possible upon request)
  • Low operating costs due to long service and test gas intervals and low consumption
  • Cost efficient with only one analyzer for up to four sampling points
  • Industry-proven S700 analyzers are the heart of the system
