Dräger Polytron 8200 CAT

Premium Stationary Combustible Gas Detection

The Dräger Polytron 8200 CAT is a top-tier, explosion-proof stationary gas detector designed for continuous monitoring of flammable gases and vapors in ambient air. Utilizing a highly advanced catalytic bead sensor (DrägerSensor DQ or DrägerSensor DD), this high-end transmitter provides rapid response times to explosive hazards. It outputs a standard 4 to 20 mA analog signal with HART digital communication, allowing for seamless integration into digital control systems and safety networks.

Poison-Resistant Sensing & Advanced Diagnostics

The catalytic bead sensors in the Polytron 8200 CAT are engineered for maximum long-term stability and unmatched poison resistance against silicones, hydrogen sulfide, and halogenated hydrocarbons. The transmitter features a matrix-backlit graphical display that provides clear real-time concentration metrics and advanced diagnostic data. Using a non-intrusive design, operators can easily perform adjustments and routine calibrations via a magnetic wand or through HART communication without opening the flameproof housing.

Modular Architecture & Digital Connectivity

Built for the most demanding industrial environments, the Polytron 8200 CAT features a rugged housing available in copper-free aluminum or 316 L stainless steel with IP65/66/67 protection. This premium model can be customized with optional fieldbus modules (such as Modbus or Profibus) and an integrated relay module. The relay upgrade provides two gas alarm relays and one fault relay, allowing the transmitter to act as an independent, standalone safety system capable of controlling local strobes, horns, and ventilation fans.

Industrial Applications & Use Cases

• Oil & Gas Refineries: Continuous explosive hazard monitoring in processing zones and pump stations.

• Chemical Processing Plants: Managing safety infrastructure where volatile flammable compounds are processed or stored.

• Wastewater Infrastructure: Tracking methane buildup in underground facilities and enclosed wet wells.

• Power Generation Facilities: Monitoring hydrogen storage areas and turbine enclosures for explosive leaks.
