DEW POINT SENSORS: A VALUABLE APPLICATION FOR COMPRESSED AIR TECHNOLOGY

June 11, 2020

Dew point monitoring is among the most important steps you can take when caring for your compressed air technology. If the dew point isn’t where it should, moisture will accumulate in your compressed air system, resulting in pipe corrosion, reduced lifespan for pneumatic parts, and even unscheduled downtime. Fortunately, thanks to massive leaps in compressed air technology, dew point monitoring is now easier and more accurate than ever before, with companies like SUTO leading the way.

One of Airtec’s most highly recommended product lines, SUTO offers compressed air technology that allows you to access data from sensors placed throughout your system, giving you a clear picture of the status of your compressed air system. With SUTO’s dew point sensors and monitors, you can see the dew points of different parts of your system in a central dashboard, helping you identify where problems might be occurring. Additionally, many SUTO sensors have automated notifications that are sent when dew points reach a certain threshold, allowing you to take control quickly.

SUTO’s Dew Point Sensors and Meters

All of the SUTO dew point sensors and meters offer rapid response time and a durable, long-lasting build. Many are also equipped with SUTO’s IP65 casing, providing robust protection for even the most rugged industrial environments. If you’re interested in learning more about any of the below or our other efficiency-boosting solutions, feel free to reach out to Airtec today!
