Oxide Moisture Sensors Since the moisture probe pore openings are small in relation to the size of most organic molecules admission into the sensor cavity is limited to much smaller molecules such as water Thus the surface of the aluminum oxide sensor which acts as a semi permeable membrane permits the measurement of water vapor pressure in organic liquids just as easily as it does in gaseous media In fact an accurate sensor electrical output will be registered whether the sensor is directly immersed in the organic liquid or it is placed in the gas space above the liquid surface As with gases the electrical output of the aluminum oxide sensor is a function of the measured water vapor pressure Moisture Content Henry s Law Type Analysis Measurement Organic When using the aluminum oxide sensor in non polar liquids having Liquids water concentrations lt 1 by weight Henry s Law is generally applicable Henry s Law states that at constant temperature the mass of a gas dissolved in a given volume of liquid is proportional to the partial pressure of the gas in the system Stated in terms pertinent to this discussion it can be said that the PPMy of water in hydrocarbon liquids is equal to the partial pressure of water vapor in the system times a constant As discussed above a GE Panametrics aluminum oxide sensor can be directly immersed in a hydrocarbon liquid to measure the equivalent dew point Since the dew point is fun

22. compressed the partial pressures of all the gaseous components are proportionally increased Conversely when a gas expands the partial pressures of the gaseous components are proportionally decreased Therefore increasing the pressure on a closed aqueous system will increase the vapor pressure of the water and hence increase the dew point This is not just a mathematical artifact The dew point of a gas with 1000 PPMv of water at 200 psig will be considerably higher than the dew point of a gas with 1000 PPMv of water at 1 atm Gaseous water vapor will actually condense to form liquid water at a higher temperature at the 200 psig pressure than at the 1 atm pressure Thus if the moisture probe is exposed to pressure changes the measured dew point will be altered by the changed vapor pressure of the water It is generally advantageous to operate the hygrometer at the highest possible pressure especially at very low moisture concentrations This minimizes wall effects and results in higher dew point readings which increases the sensitivity of the instrument Response Time The response time of the GE Panametrics standard M Series Aluminum Oxide Moisture Sensor is very rapid a step change of 63 in moisture concentration will be observed in approximately 5 seconds Thus the observed response time to moisture changes is in general limited by the response time of the sample system as a whole Water vapor is absorbed tenaciously by many materi
