  1. H2O Sensor Technology

  2. Objective of Presentation Physics of Technology Installation Requirements Drawings & Applications

  3. Physics of Technology • Absolute Humidity Sensor • Direct measurement of the water molecule • Dipole moment measuring effect • In-situ measurement • Advantages • High temperature operation – 850F • High particulate operation • Minimal maintenance • Corrosive and condensing environments are not an issue • Accurate • Robust (sensor life is 10 years minimum)

  4. Installation Requirements • Probe sizes – 490 mm or 1,470 mm lengths • Flange - 4 inch, 150 lb ANSI • Power – 110V, 5 Amps • Output Signal – 4..20 mA isolated • Measurement unit – g/m3 corrected to 0C at process pressure • Other Units – Equations are provided (i.e., dewpoint, RH, humidity ratio)

  5. Picture / Drawing
