Com.Air - Dew Point Monitor for Compressed Air Systems - DESCRIPTION

Manufactured by EdgeTech Instruments

The COM.AIR dew point monitor has been 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, and a precision platinum resistance thermometer to measure the mirror temperature. The CM uses a thermo-electric device to control the temperature of the mirror in determining dew point. Since 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 ruggedized aluminum NEMA-12 enclosure houses the sensor, control circuitry, as well as flow control and is easily wall-mounted to conserve space. Only the sample line and power connection is needed for the system to be operational. Com.Air also offers a programmable Automatic Balance Control (ABC) cycle which corrects for the light reducing effects of mirror contaminates and allows 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, you would choose between a two or three stage sensor and also choose if the sensor needed 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.

Using 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 lowest cost (S series).

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