Dräger Pulsar 7000 Series

Open-Path Infrared Flammable Gas Detection

The Dräger Pulsar 7000 Series represents the pinnacle of open-path line-of-sight gas detection, engineered for the continuous monitoring of combustible hydrocarbons. Spanning distances up to 200 meters, this high-performance system consists of an infrared transmitter and receiver pair. By covering expansive perimeters and vast process structures, the Pulsar 7000 Series instantly flags gas clouds passing through its optical path, offering maximum safety coverage for critical industrial complexes.

Resilient Optical Performance in Adverse Weather

Equipped with high-intensity xenon flash lamps and advanced digital signal processing, the Pulsar 7000 Series is highly resilient against false alarms caused by harsh environmental conditions. The system operates with total reliability through thick fog, heavy rain, snowstorms, and solar glare. For extreme climates, the receiver and transmitter windows feature built-in internal heated optics to continuously eliminate ice, condensation, and frost accumulation, ensuring a constantly clear optical safety line.

Fast Commissioning and Built-In Data Integrity

Alignment and commissioning are made effortless by a specially calibrated alignment telescope and digital optimization indicators, saving substantial operational downtime during field deployment. The unit utilizes an internal data logger to record historical fault events, warning statuses, and light attenuation trends for rigorous safety auditing. The device communicates over a standard 4 to 20 mA loop alongside a digital HART interface, facilitating simple remote diagnostics and integration into plant safety networks.

Industrial Applications and Use Cases

• Offshore Oil & Gas Rigs: Monitoring long perimeters, platform edges, and processing decks for volatile hydrocarbon leaks.

• Onshore Refineries & Tank Farms: Guarding massive fuel storage tanks and long-distance cross-country transfer lines.

• LNG / LPG Terminals: Fast line-of-sight explosive cloud tracking at loading docks and cryogenic storage facilities.

• Chemical Manufacturing Infrastructure: Providing fence-line safety surveillance across expansive open-air plant zones.
