WADS 205 – Dew Point Monitor for Compressed Air

Model Selector (WADS 205 / 206)

Use this selector to generate the correct ordering code based on pipe size and options.

The WADS 205 is a wall-mounted dew point monitor designed for continuous moisture monitoring in compressed-air systems. It provides plant engineers and operators with a local view of pressure dew point, making it practical for dryer rooms, plant utility areas and production environments where compressed-air quality needs to be checked during routine rounds. The wall-mounted design allows the reading to be viewed directly without opening a control panel or relying on a remote dashboard.

Moisture in compressed air can affect downstream filters, pneumatic equipment and product quality, while a change in dew point can indicate reduced dryer performance. The WADS 205 helps maintenance teams monitor these changes continuously. Available models cover dew point ranges from -110°Ctd to +60°Ctd, with accuracy up to ±2°Ctd, allowing the appropriate configuration to be selected according to the plant’s moisture-monitoring requirements.

How Does the WADS 205 Support Moisture Monitoring in Compressed Air?

The WADS 205 combines dew point measurement with an integrated MEMS-based pressure sensor in selected configurations. Measuring line pressure along with dew point helps engineers assess the actual pressure dew point rather than relying on an assumed operating pressure. This is particularly useful when monitoring compressed-air dryers, where changes in pressure and moisture conditions need to be considered together.

For maintenance teams, continuous moisture monitoring in compressed air provides an early indication of changes in dryer performance before moisture becomes a visible problem downstream. The available options can provide local indication and alarm functions, allowing operators to respond when the measured dew point moves outside the required operating condition. This makes the WADS 205 suitable for plants where the reading needs to be visible and actionable at the point of monitoring.
