Drager Pulsar 7000 Manual //top\\
The Pulsar 7000 is ATEX and IECEx certified for Zone 1 and Zone 2 explosive gas atmospheres.
0 to 4 LEL*m or 0 to 8 LEL*m (Lower Explosive Limit
The Pulsar 7000 features internal window heaters to prevent condensation, frost, and ice. Verify via the software that the heaters are functioning if operating in freezing climates. 6. Troubleshooting Common Faults Symptom / Fault Code Root Cause Resolution Output Beam Blocked or dirty windows. Clean lenses; remove physical obstructions between units. Output Hardware fault or critical misalignment. Re-align the units; check internal diagnostics via HART. Drifting Zero Point Structural shifting or dirty optics during zeroing. Clean windows thoroughly and re-run the Zero Calibration. No Communication drager pulsar 7000 manual
Sudden structural shift, a physical obstruction (like a newly parked vehicle or scaffold), or a failed flash lamp inside the transmitter.
The internal terminal strip typically includes the following connections: The Pulsar 7000 is ATEX and IECEx certified
Because open-path detectors cannot be easily calibrated with a standard gas bottle and cup, Dräger utilizes or specialized gas check cuvettes .
Elias cut him off, his voice rising. "The manual says 'Do NOT rely on auxiliary sensors.' The air is moving fast, and my sentry is asleep! Pull the crew, Kael. Pull them now." Output Hardware fault or critical misalignment
When hydrocarbon gases cross the invisible light beam between the transmitter and receiver, they absorb specific wavelengths of the infrared light. The receiver measures this drop in intensity and calculates the gas concentration. Unlike point detectors that measure gas at a single spot, the Pulsar 7000 measures gas concentration over the entire path length, expressed in . Key Technical Specifications
Insert the Dräger-approved test card or gas-filled cuvette into the receiver's optical path slot.
The Pulsar 7000 is an open-path infrared (IR) detector, meaning it uses a beam of infrared light to detect gas clouds between a transmitter and a receiver, covering distances up to 200 meters.
