Dräger Polytron 5200 CAT

Advanced Stationary Combustible Gas Detection

The Dräger Polytron 5200 CAT is an explosion-proof, industrial-grade stationary transmitter designed for the continuous monitoring of flammable gases and vapors in ambient air. Utilizing a highly responsive catalytic bead sensor (DrägerSensor MQ or DrägerSensor DD), this advanced system provides early warning signs of explosive hazards. It effectively converts gas concentrations into a standardized 4 to 20 mA analog signal, allowing seamless integration into existing industrial safety frameworks and control rooms.

Poison-Resistant Sensing and Simple Maintenance

Engineered for maximum reliability, the catalytic bead sensors inside the Polytron 5200 CAT offer exceptional long-term stability and poison resistance against silicones, hydrogen sulfide, and halogenated hydrocarbons. The transmitter features an intuitive, backlit graphical display that presents real-time gas measurements and diagnostic codes clearly. For routine maintenance and calibration, operators can utilize a convenient magnetic wand to interact with the device non-intrusively, keeping the system sealed and certified without declassifying the hazardous area.

Rugged Architecture and Standalone Capability

Built to perform in the harshest industrial climates, the transmitter housing is available in either copper-free aluminum or premium 316 L stainless steel, complete with an IP65/66/67 ingress protection rating. An optional integrated relay module expands the unit into an independent safety node. This module includes two gas alarm relays and one fault relay, giving the Polytron 5200 CAT the power to automatically actuate local alarms, strobes, or ventilation fans without relying on a central controller.

Industrial Applications and Use Cases

• Oil & Gas Refineries: Continuous surveillance for explosive hydrocarbon leaks in processing units.

• Chemical Manufacturing Plants: Mitigating combustion hazards by tracking volatile flammable solvents.

• Wastewater and Sewage Facilities: Detecting hazardous methane gas buildup in underground wet wells.

• Automotive and Painting Facilities: Monitoring vapor concentration levels in solvent storage rooms and spray booths.
