DEW POINT SENSOR
MEASURE TO MANAGE
2.1 Importance of Dew Point:
When it comes to monitoring compressed air systems, nothing offers a
better payback than a dew point sensor. Once you have moisture in your system,
everything becomes a problem. If you have ever had this occur, you'll know the
problem occurred days before you discovered it and it took even longer to dry out
after the issue was fixed.
Most people don't think of dew point sensors as providing efficiency, but
wet compressed air will do irreparable damage to components, create reliability
issues throughout your entire plant and allow bacteria, rust and corrosion to
build up in your system. Moisture issues are extremely difficult to rectify and
component failures will go on for years.
If you have a system running a desiccant dryer or with a specified purity
requirement, then you are already demonstrating your dew point is a critical
component of your system and therefore should be monitored continuously.
2.2 Indicators on Refrigerant Dryers Don't Measure Dew Point
The indicator on your refrigerant dryer is exactly that, an indicator, it is not
measuring the dew point entering your plant. It is only measuring the
temperature of the refrigerant gas. Any number of issues before and after your
dryer can lead to the dew point deteriorating and they will not be shown on the
dryer indicator.
Compared to your compressed air system, dew point sensors are cheap,
easy to install and have low maintenance requirements. They are the most cost
effective sensor purchase you are ever likely to make.
2.3 Benefits of Monitoring Dew Point
Improve system reliability
Reduce product contamination risks
Reduce system maintenance
Reduce operating and energy costs
Reduce the risk of rust and corrosion build up
Improve dryer reliability
