Dräger Polytron 5200 CAT Fixed Flammable Gas Detector (LEL Transmitter)

The Dräger Polytron 5200 CAT is a cost-effective, explosion-proof fixed flammable gas detector (LEL transmitter) for continuous monitoring of combustible gases and vapors in industrial hazardous areas in India. Featuring a robust catalytic bead sensor and 4-20 mA output with optional relays, it offers reliable, long-life gas detection for critical safety applications.

Instrusense India presents the Dräger Polytron 5200 CAT, a high-performance, cost-effective explosion-proof (Ex ‘d’ or ‘d/e’) transmitter engineered for the continuous and reliable detection of flammable gases and vapors within the Lower Explosive Limit (LEL). Utilizing the innovative, long-life catalytic bead DrägerSensor Ex DQ/DD, the Polytron 5200 ensures superior stability and enhanced poison resistance, minimizing maintenance costs and maximizing uptime in Indian refineries, chemical plants, oil & gas, and battery room applications.

As a member of the Dräger Polytron 5000 series, it shares a uniform design and user interface, simplifying operation, training, and spares management. Key features include an easy-to-read, backlit graphic LCD display and a non-intrusive magnetic wand for safe, one-person calibration and maintenance in hazardous environments. Its versatile architecture supports a 3-wire 4-20 mA analog output, making it seamlessly compatible with most industrial control systems (DCS, PLC).

For standalone or localized safety systems, the Polytron 5200 is available with three optional integrated relays (two alarm, one fault), enabling local control of horns, lights, and valves without requiring a separate central controller. The robust, explosion-proof housing, available in epoxy-coated aluminum or 316L stainless steel, provides maximum protection (IP65/66/67, NEMA 4X & 7) against harsh environmental conditions prevalent across industrial sites in India. Remote sensor mounting options further enhance its versatility for monitoring in hard-to-reach or high-temperature locations. Instrusense India is your trusted source for the genuine Dräger Polytron 5200, ensuring top-tier industrial safety.
