Com.Air Dew Point Monitor for Compressed Air Systems - DESCRIPTION
by EdgeTech Instruments

The COM.AIR dew point monitor is designed by Edgetech Instruments to offer the highest level of reliability and accuracy available in compressed air system dew point measurement. It is equally valued in determining dew point in purge gas systems used in metal heat treating, solder reflow ovens, and purged tunnel processes. The COM.AIR uses the chilled mirror (CM) dew point temperature condensation principle to determine the water vapor concentration in gas mixtures, with a precision platinum resistance thermometer to measure the mirror temperature. The CM uses a thermo-electric device to control the temperature of the mirror and determine dew point. It is a direct measurement of dew point and, thus, a Primary Standard Measurement Technique. The COM.AIR is highly regarded by manufacturing engineers for its robust packaging, accuracy, long life, fast response in detecting upset conditions, and easy-to-use characteristics.

Com.Air is a complete dew point monitoring System. The rugged aluminum NEMA-12 enclosure houses the sensor and control circuitry, as well as flow control, and is easily wall-mounted to conserve space. Only the sample line and power connection are needed for the system to be operational. Com.Air also offers a programmable Automatic Balance Control (ABC) cycle that corrects for the light-reducing effects of mirror contaminants, allowing for continuous monitoring and virtually maintenance-free operation. Several models of chilled mirror sensors are available for the COM.AIR. In most cases, the COM.AIR is fitted with a flow-through sensor, such as the S-Series or X3 series sensors. Gas is extracted from the process point and flows through the sensor for measurement. Depending on the target dew point, choose between a two- or three-stage sensor while deciding if the sensor needs to be air-cooled, fan-cooled, or liquid-cooled. The standard configuration is to mount the sensor onto the face of the COM.AIR unit.

Use of the X3 or the standard S series sensor is determined by the need for chemical resistance (X3), the need for measuring lower dew points without the need for liquid cooling (X3), or the need for the lowest cost (S series).

Remote sensor mounting (locating the sensor away from the electronics) is possible by specifying the insertion D-Probe, the S-series or the X3 series, all with remote cable. The D-Probe can actually be mounted within many processes. The X3 and S series are extractive sampling.
