Emerson AVENTICS DS1 dew point sensor

Emerson has launched the AVENTICS DS1 dew point sensor, an industrial sensor that is designed to monitor dew point, temperature, humidity levels, and quality of compressed air and other non-corrosive gases in real time from one device. The sensor can help operators detect and mitigate excess moisture in its early stages and prevent moisture-related equipment damage. By optimising air quality in this way, operators can better control processes, extend pneumatic component life, and reduce maintenance and unplanned downtime.

While many industrial sensors only monitor humidity, the DS1 provides dew point monitoring that enables manufacturers to continuously track critical values, address excess moisture and prevent its negative effects. For instance, moisture can affect process reliability by corroding components, washing the lubrication out of moving parts, and extending switching and reaction times. The sensor also allows operators to detect changes in air quality in real time, providing data that facilities need to maintain a stable dew point and protect product quality.

To support industrial digital transformation strategies, the dew point sensor can be integrated into existing systems, including the AVENTICS Series AS3 and AVENTICS Series 652 air preparation units, and connects to networks via Modbus TCP (PoE). One of the key advantages of an integrated dew point sensor is the ability to place the sensor — and track conditions — close to the process rather than where the compressed air is generated, which can be far from the process itself and have very different conditions.

The sensor element is condensation-resistant and provides long-term, drift-proof performance. With fast response time, measurement values include pressure dewpoint, temperature, relative humidity, absolute humidity, moisture content, moisture content V/V, water vapour partial pressure and atmospheric dew point. The sensor is also suitable for other non-corrosive gases, including nitrogen, oxygen, argon, helium and sulfur hexafluoride.
