ABSTRACT:
The apparatus and method for reducing or eliminating dew point measurement error caused by the presence of water soluble contaminants at the condensing surface. The method which consists of cooling the condensing surface to a temperature well below the prevailing dew point for a time sufficient to provide a heavy growth and coalescence of the condensate so as to dissolve all of the soluble material and create a medium by which ions of solute can migrate. Immediately after cooling, the condensing surface is heated to a temperature well above the prevailing dew point so as to cause total evaporation of the solvent (condensate) and recrystallization or precipitation of the solute into clusters or isolated colonies.
The resulting change in mirror reflectance is compensated by automatic adjustment of the light intensity of the source which illuminates the site of the condensate for photo-detection of the onset of dew. The apparatus which performs the above-described operation then reverts back to normal operation wherein the condensing surface is cooled to and controlled at the prevailing dew point. The net effect is that the solute material which prior to the above operation covered the condensing surface and which modifies the vapor pressure of the condensate, has been redistributed so as to provide a substantial surface where condensation can occur in the absence of solute. The system then controls at the equilibrium temperature which is established by the vapor pressure of pure water so that the measurement error is eliminated.
