Protecting Compressed Air
Quality at the Source
Detecting minor variations in dew point temperature can have a significant impact on the overall quality of compressed air.
Uncontrolled moisture in a compressed air system leads to corrosion, valve sticking, instrumentation problems and product defects. Reliable dew point measurement is the most effective way to confirm that drying equipment is performing and that air quality is maintained.
The recommended approach is pressure dew point (PDP) monitoring — the temperature at which water condenses at line pressure rather than atmospheric pressure. PDP monitoring confirms dryer effectiveness, detects moisture events early and helps prevent costly over-drying.
Five Measurement Strategies
Different systems call for different measurement approaches. These five strategies cover the full range of compressed air applications.
Continuous Inline Monitoring
Permanent dew point measurement directly inside pressurised pipelines for real-time visibility of compressed air quality.
Compact Transmitters for Dryers
Space-saving transmitters integrated into refrigerant and desiccant dryers and OEM skids to verify performance at the source.
Plant-Wide Standardisation
Modular transmitter platforms deployed across a facility to standardise measurement and simplify maintenance and calibration.
Portable Verification
Handheld instruments for maintenance, commissioning and troubleshooting — confirming readings wherever they are needed.
Sampling Accessories
Sampling cells and accessories that protect sensors and deliver reliable readings in contamination-prone systems.
