Drager Pulsar 7000 Manual Jun 2026

Supports HART® protocol, Modbus, and 4-to-20 mA analog outputs. Technical Performance Data Specification Measuring Range 0 to 4 LEL x m or 0 to 8 LEL x m Response Time ( T90cap T sub 90 ) Less than 2 seconds Operating Temperature -55 °C to +65 °C Ingress Protection IP65, IP66, and IP67 Supply Voltage 18 to 32 V DC (24 V DC nominal) 2. Safety and Compliance Instructions

For a device as critical as a gas detector, relying on guesswork is not an option. The official Instructions for Use (IFU) and other related manuals are not just paperwork; they are the definitive source of truth for:

Current levels exceeding 20 mA indicate that the gas concentration has surpassed the calibrated measurement range of the device. 5. Safety and Maintenance Standards

Place the specialized calibration test film (which simulates a specific LEL-m gas concentration) directly into the slot on the receiver's weather shield. drager pulsar 7000 manual

The various Pulsar 7000 manuals provide detailed, step-by-step guidance for critical tasks.

4 to 20 mA analog interface alongside digital HART® communication.

The manual emphasizes that the first few seconds are the most dangerous. Panic often leads to improper usage. Supports HART® protocol, Modbus, and 4-to-20 mA analog

Use shielded, twisted-pair cabling for signal lines (minimum 0.5 mm² or 20 AWG; 1.5 mm² or 16 AWG is recommended for long distances to minimize voltage drops).

The Dräger Pulsar 7000 series represents the pinnacle of open-path gas detection technology. Designed to detect explosive hydrocarbons over long distances, these open-path infrared gas detectors are critical safety components in oil and gas, petrochemical, and industrial processing facilities.

The Dräger Pulsar 7000 communicates its operating status via standard 4-20 mA current loops. The manual defines the standard current outputs as follows: Current Output (mA) System Status Description / Action Required Serious Fault Hardware failure or complete loss of power. Beam Blocked

: A "rough" visual alignment is followed by fine adjustment using a handheld terminal. The system provides a digital coordinate display to help a single operator optimize the beam's signal strength.

Adjust the vertical (tilt) screw until the peak signal is reached.

The is a critical document for facilities requiring certified functional safety. Its purpose is to document all necessary information and assumptions required for integrating the Pulsar 7000 gas warning system into a Safety Instrumented System (SIS) . This manual details assumptions and restrictions, training and installation requirements, proof test procedures, and all safety-relevant parameters.
