6 Pressure (mbar) Moisture..is the amount of water vapor present in a given sample It can be expressed in different units> Solid, ice Liquid Vapor Water vapor pressure [mbar] Dew point temperature [ o C] Relative humidity [%] Absolute humidity [g/m 3 dry air] 0.16 Temperature (oc) Volumetric concentration [ppmv] Mixing ratio [g/kg] Wet bulb temperature [ o C]

7 Water Molecule H 2 O One Oxygen atom Two Hydrogen atoms M w = 18 Hydrogen atoms bond to one side of oxygen atom Polar molecule Part of the molecule is negatively charged and part positively charged. Hydrogen atoms in water molecules are attracted to regions of high electron density and can form weak linkages Can adsorb to surfaces

8 Dew Point Frost Point The temperature to which a gas must be cooled to be saturated with respect to liquid water - or - The temperature to which a gas must be cooled where the first molecule of water vapor changes to the liquid phase. The temperature to which a gas must be cooled to be saturated with respect to ice (solid water). - or - The temperature to which a gas must be cooled where the first molecule of water vapor changes to the solid phase.

12 Aluminum Oxide Sensor Theory Water vapor rapidly transports through the gold layer and equilibrates to the pore walls of the aluminum oxide layer. The number of water molecules adsorbed onto the pore walls determines the conductivity of the pore wall. Each value of pore wall resistance provides a distinct value of electrical impedance, which in turn is related to the water vapor pressure. Permeable gold Pore Pore base Aluminum
