    Title: Atmospheric Pressure (altitude) Range

    Type: Text and Image Slide

    Content:
    • Oxygen Sensors
      • Partial pressure sensors
        • partial pressure of oxygen forces oxygen through diffusion membrane
        • changes in atmospheric pressure or altitude will affect the measurement
      • Capillary sensors
        • oxygen enters sensor through small tube
        • not affected by changes in atmospheric pressure or altitude.
        • capillary may be blocked by fluids
