Product Specifications

Technical details and manufacturing context for Sampling System (for aspirated detectors)

Definition
A critical component of gas detection systems that uses pumps or fans to continuously or periodically extract air samples from potentially hazardous locations and transport them through tubing to remote aspirated detectors for precise gas concentration measurement, enabling early warning of leaks or dangerous accumulations in hard-to-reach or confined spaces.
Working Principle
Utilizes a vacuum pump or fan to create negative pressure, drawing air samples through sampling probes and transport tubing to the detector. The system may include filters to remove particulates, moisture traps, flow sensors, and calibration ports to ensure accurate sample delivery and detector performance.
Common Materials
Stainless steel, PTFE (Teflon), Polyethylene, Polyurethane

Unsuitable: High particulate environments (>100 mg/m³) without pre-filtration
Sizing Data Required
  • Maximum sampling distance (tube length)
  • Number of sampling points/zones
  • Required response time for gas detection

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Filter clogging
Cause: Accumulation of particulate matter, dust, or environmental contaminants on the intake filter, restricting airflow and reducing sampling efficiency.
Pump failure
Cause: Wear or malfunction of the aspiration pump due to continuous operation, lack of lubrication, or ingestion of corrosive or abrasive substances from the sampled environment.
Maintenance Indicators
  • Decreased or fluctuating flow rate readings on the system's flow indicator
  • Audible changes in pump operation (e.g., increased noise, grinding sounds, or complete silence when pump should be running)
Engineering Tips
  • Implement a regular preventive maintenance schedule for filter inspection and replacement based on environmental conditions, not just time intervals.
  • Install a secondary particulate filter or moisture trap upstream of the main filter to protect the pump and primary filter from coarse contaminants and condensation.
