Here are some key factors by our experience you should consider when choosing a dew point sensor for your air dryer device:

• Accuracy and Reliability: This is arguably the most important factor. The sensor needs to consistently measure extremely low moisture levels to ensure your compressed air meets the required dryness specifications. Look for sensors with high accuracy ratings and a proven track record of reliability.

• Reaktionszeit: The sensor should be able to detect changes in dew point quickly. This is particularly important for systems where moisture content can fluctuate rapidly. A fast response time allows for prompt corrective action if the dew point rises above the desired level.

• Stabilität: Over time, some sensors can drift, meaning their readings become less accurate. Choose a sensor with good long-term stability that minimizes drift and requires minimal recalibration.

• Contaminant Resistance: Compressed air can contain oil vapors and particulates. The sensor should be resistant to these contaminants to ensure accurate readings and avoid malfunction. Some sensors may require filters to protect them from contamination.

• Ease of Maintenance and Calibration: Regular maintenance and calibration are essential for any dew point sensor. Consider how easy it is to access the sensor for maintenance and how often calibration is required.

• Operating Environment: Consider the temperature and pressure range the sensor will be operating in. Make sure the sensor is rated for the conditions within your air dryer system.

Consulting with a compressed air system specialist can be helpful in choosing the right dew point sensor for your specific application. They can help you assess your needs and recommend sensors that meet your requirements.
