Dräger Polytron 8310 IR

Premium Stationary Infrared Flammable Gas Detection

The Dräger Polytron 8310 IR is a top-tier, explosion-proof stationary gas detector designed for the continuous monitoring of flammable gases and vapors in ambient air. Utilizing an advanced, poison-resistant infrared sensor (DrägerSensor IR), this premium transmitter delivers exceptional measurement accuracy and rapid response times. It converts gas concentrations into a standard 4 to 20 mA analog output with HART digital communication, allowing seamless integration into sophisticated asset management networks and safety control systems.

Poison-Resistant Sensing and Advanced Diagnostics

Unlike traditional catalytic bead sensors, the optical infrared technology inside the Polytron 8310 IR is completely immune to sensor poisons such as silicones, sulfur compounds, and halogenated hydrocarbons. It operates reliably in oxygen-deficient or completely inert atmospheres. The transmitter features a matrix-backlit graphical display that presents real-time gas measurements and diagnostic codes clearly. Thanks to its non-intrusive design, operators can use a magnetic wand to calibrate or configure settings without opening the flameproof housing or declassifying the hazardous area.

Modular Architecture and Digital Connectivity

Built to excel in the most punishing 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. This high-end 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, enabling the Polytron 8310 IR to act as an independent, standalone safety system that automatically actuates local horns, strobes, or ventilation fans.

Industrial Applications and Use Cases

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

• Chemical Processing Plants: Mitigating combustion risks by tracking volatile flammable solvents and hydrocarbons.

• Wastewater Infrastructure: Tracking methane and combustible gas buildup in humid, corrosive wet wells.

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