Product Specifications

Technical details and manufacturing context for Sample Intake System

Definition
The Sample Intake System is a critical component of the Atmosphere Analyzer that facilitates the controlled acquisition and delivery of environmental samples to the analyzer's detection and measurement modules. It ensures representative sampling while maintaining sample integrity through proper flow regulation, filtration, and conditioning.
Working Principle
Operates by drawing ambient air or gas through an inlet probe, passing it through filters to remove particulates, regulating flow via pumps or valves, and conditioning the sample (e.g., temperature stabilization, humidity adjustment) before delivering it to the analyzer's sensors for compositional analysis.

Sizing Data Required
  • Required sample flow rate (L/min)
  • Maximum particle size in sample (microns)
  • Required response time for sample delivery (seconds)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Abrasive erosion
Cause: Ingestion of particulate matter (e.g., sand, dust) causing progressive material loss on intake surfaces, especially at bends and restrictions.
Cavitation
Cause: Localized pressure drops below vapor pressure in the intake flow, forming and collapsing vapor bubbles that cause pitting and erosion on component surfaces.
Maintenance Indicators
  • Unusual whistling or hissing noises indicating air leaks or flow restrictions
  • Visible material thinning, pitting, or discoloration on intake ducting or filter housings
Engineering Tips
  • Install properly sized and maintained pre-filtration systems to reduce abrasive particle ingress
  • Optimize intake geometry and flow velocity to maintain pressure above vapor pressure, preventing cavitation
