FOR MONITORING THE LOWER EXPLOSION LIMIT IN FLAMMABLE GASES • T90 response time in less than 4 seconds (including sampling). • High reliability • Low investment costs thanks to a multi-point layout. • Possibility of heating the analysis and the sample up to 180°C. • Compact wall, rack, outdoor or ATEX area mounting.

PRINCIPLE OF FID DETECTOR FID: Flame Ionization Detector Through the combustion of clean air, hydrogen and sample gases, the FID detects hydrocarbon ions that induce a current. This current is directly proportional to the organic concentration in the sample gas. The FID is considered the most accurate and reliable detector on the market for organic compounds. It is suitable for any type of application, including those for high-temperature samples.

HOW IT WORKS The sample is continuously sucked from the sampling probe and routed through the analyzer for measurement. If the set concentration limit is exceeded, the system status contacts are activated. Safety integration: The analyzer interfaces with the plant's PLC logic via free contacts (NC), ensuring an immediate and reliable response.

MULTIPLE LAYOUTS AVAILABLE Compact, wall mounted, single or multi-line (max.2) ATEX rack, with H2 leak sensor and air conditioner, single or multi-line (max.2) Rack, with H2 leak sensor and air conditioner, single or multi-line (max.10)

COMPARISON OF FLAME LEL MONITORING SYSTEMS Traditional flame detector Frequent because of large Span/zero drifts in time. Reduced, thanks to sampling loop technology and multi-point layouts Stability Readings Unstable with interferers (e.g. water or oxygen content variations) Very stable and optimized for common interferents Conforms to EN 60079-29-1 ed EN 1539 (regulations for ovens)

• Consumption = 4 m3/hour (more cunsumption if more than 4 lines are applied) Power Supply
