8. Application of the Hygrometer A 5 August 2004 Contaminants Non Conductive Particulates Industrial gases and liquids often contain fine particulate matter Particulates of the following types are commonly found in such process fluids carbon particles salts rust particles polymerized substances organic liquid droplets dust particles molecular sieve particles alumina dust For convenience the above particulates have been divided into three broad categories Refer to the appropriate section for a discussion of their affect on the GE Infrastructure Sensing moisture probe Note Molecular sieve particles organic liquid droplets and oil droplets are typical of this category In general the performance of the moisture probe will not be seriously hindered by the condensation of non conductive non corrosive liquids However a slower response to moisture changes will probably be observed because the contaminating liquid barrier will decrease the rate of transport of the water vapor to the sensor and reduce its response time Particulate matter with a high density and or a high flow rate may cause abrasion or pitting of the sensor surface This can drastically alter the calibration of the moisture probe and in extreme cases cause moisture probe failure A stainless steel shield is supplied with the moisture probe to minimize this effect but in severe cases it is advisable to install a Teflon or sta
9. few microns of mercury up to pressures of 5000 psig The calibration data supplied with the moisture probe is directly applicable over this entire pressure range without correction Note Although the moisture probe calibration data is supplied as meter reading vs dew point it is important to remember that the moisture probe responds only to water vapor pressure When a gas is 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 ppm of water at 200 psig will be considerably higher than the dew point of a gas with 1000 ppm 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 T
