Measurement Technology<\/strong><\/h3>\n

The Condumax II<\/strong> employs two synergistic measurement methods:<\/p>\n

Hydrocarbon Dew\u2011Point Measurement \u2013 Dark Spot\u2122 Chilled Mirror:<\/strong>
\nThe primary hydrocarbon dew-point channel uses the Dark Spot\u2122 direct chilled\u2011mirror technique<\/strong>. In this method, a Peltier\u2011cooled mirror surface<\/strong> within the hydrocarbon sensor cell is progressively cooled under electronic control. When hydrocarbon condensate begins to form on the mirror, a secondary optical effect<\/strong> is detected as a reduction in scattered light intensity from a collimated beam reflected from the mirror\u2019s surface. This point of optical change is used to define the hydrocarbon dew point<\/strong> directly, with objective and repeatable results.<\/p>\n

The multi\u2011stage Peltier cooling system provides controlled cooling<\/strong> to achieve measurement depressions as low as \u0394\u201155\u202fK beyond ambient analyzer temperature, ensuring accurate detection of condensate formation.<\/p>\n

This direct optical condensation measurement is fundamental and primary<\/strong>, meaning there is no reliance on empirical correlations \u2014 the dew point is determined by the actual onset of condensation, making the technique inherently accurate and stable.<\/p>\n

Water Dew\u2011Point Measurement \u2013 Ceramic Moisture Sensor (Optional):<\/strong>
\nFor simultaneous water dew point analysis, Condumax II can accommodate an optional water dew\u2011point channel<\/strong> based on Michell\u2019s Ceramic Metal\u2011Oxide Moisture Sensor<\/strong>. This sensor utilizes a ceramic metal\u2011oxide impedance sensing element that responds to changes in moisture content in the gas stream with measured impedance changes. These changes are converted into dew\u2011point values and moisture content in various units (\u00b0C, \u00b0F, ppmV, mg\/m\u00b3, etc.), providing complementary data to hydrocarbon dew-point measurements.<\/p>\n
