Catalytic Bead DrägerSensor®

High-Performance Combustible Gas Sensor

The Catalytic Bead DrägerSensor® is a highly sophisticated electrochemical sensor designed for the continuous detection and monitoring of flammable gases and vapors. Operating on the proven pellistor principle, this sensor delivers exceptional stability, long-term precision, and fast response times to mitigate explosion hazards across heavy industrial sectors.

Superior Poison Resistance and Stability

Traditional catalytic bead sensors can suffer from desensitization when exposed to specialized chemical compounds. This advanced Dräger sensor utilizes premium pellistor formulations to maintain optimal operation under demanding workloads:

• Excellent Poison Poisoning Immunity: High resistance against typical poisoning agents such as silicones, sulfur compounds, heavy hydrocarbons, and halogenated hydrocarbons.

• Long Operational Lifespan: Optimized catalytic elements ensure a high level of performance continuity and reduced calibration frequency.

Key Features and Industrial Benefits

• Fast Speed of Response (t50/t90): Provides immediate alarm triggers upon detecting combustible targets, granting safety systems precious seconds to initiate automated shutdowns.

• Broad Substance Detection: Calibrated to accurately detect a wide spectrum of flammable gases from hydrogen and methane to complex hydrocarbons.

• Plug-and-Play Integration: Seamlessly hot-swappable with compatible Dräger Polytron and SE ex-transmitters without modifying system configurations.

• Robust Metal Mesh Guard: Features an integrated, explosion-proof stainless steel flame arrestor that protects internal active elements while maximizing gas diffusion.
