Dräger PSD 3000

Continuous Gas Sampling for Advanced Stationary Gas Detection Systems

The Dräger PSD 3000 is an industrial-grade, fixed sampling unit engineered for the continuous extraction and delivery of gas and air mixtures to gas monitoring systems. When paired with stationary gas transmitters, the PSD 3000 creates a highly reliable remote sampling system, enabling precise gas detection in deep wells, isolated pipelines, high-temperature conduits, and areas where physical access is restricted or hazardous.

Vibrating Diaphragm Technology and Low-Maintenance Operation

At the mechanical core of the Dräger PSD 3000 is an innovative vibrating diaphragm pump. By entirely removing standard rotating engine components, this unique design eliminates mechanical wear points and dramatically extends operational life expectancy while decreasing facility maintenance overhead. To ensure long-term stability and equipment longevity, an integrated internal dust filter protects the internal sampling pump mechanics from airborne particulate matter, dust, and liquid aerosols.

Intelligent Flow Monitoring and Flexible Control Integration

The PSD 3000 features advanced electronic circuitry that continuously monitors the volume flow rate of the extracted gas sample. If an inlet sampling line becomes blocked or the flow rate falls below a predefined threshold, the system triggers an automatic low-flow alert. Operators can configure this diagnostic message flexibly, routing the signal to a central control panel via standard 4 to 20 mA analog looping or through dedicated, separate fault switching contacts. Local status is also indicated clearly using an integrated, multi-colored LED indicator that identifies normal operation, blocked lines, or electrical faults.

Industrial Applications and Use Cases

• Confined Space Monitoring: Safely sampling target atmospheric baselines in storage silos, deep storage tanks, and underground sewer wells before personnel entry.

• Extreme Processing Conduits: Drawing gas samples out of hot, pressurized, or high-vibration ducting without risking damage to sensitive stationary transmitters.

• Cleanroom Surveillance: Remotely testing high-purity processing rooms from external maintenance corridors to preserve sterile conditions.

• Remote Stack Sampling: Extracting exhaust gas and ambient emission mixtures along complex pipe racks and overhead facility stacks.
