Dräger PIR 3000

Explosion-Proof Infrared Gas Transmitter

The Dräger PIR 3000 is an explosion-proof gas detector designed for the continuous monitoring of combustible gases and vapors containing hydrocarbons. Utilizing state-of-the-art infrared (IR) optical sensor technology, this robust transmitter delivers exceptional long-term stability and precise lower explosive limit (LEL) monitoring without the risk of sensor poisoning.

Poison-Exempt Infrared Sensing Technology

Unlike traditional catalytic bead detectors, this optical system is completely immune to airborne contaminants, dramatically dropping ongoing operational overhead:

• Immunity to Sensor Poisons: Unaffected by typical industrial toxins such as silicones, hydrogen sulfide, halogenated hydrocarbons, and sulfur compounds.

• Failsafe Optical Operations: Built-in optical path diagnostics continuously verify proper internal operations, ensuring the detector fails to a safe status rather than remaining silent.

Key Features and Industrial Benefits

• Stainless Steel SS 316 Housing: Encased in a heavy-duty, marine-grade stainless steel enclosure with an IP65/66/67 rating to withstand corrosive coastal and offshore environments.

• Double-Compensated Optics: Employs a non-dispersive infrared (NDIR) dual-beam system that maintains accuracy despite dust accumulation or changing thermal profiles.

• Gas Library Versatility: Pre-calibrated for methane, propane, and ethylene, with specialized linear response curves optimized for broad hydrocarbon tracking.

• Seamless System Interfacing: Standardized 4 to 20 mA analog signal output integrates effortlessly with plant-wide controllers, controllers, and distributed PLCs.
