High-Precision Industrial-Grade Dew Point Sensor for Industrial Compressed Air

Dew point is the temperature at which the water vapor in the air becomes saturated. That is, when the air cools to this temperature, water vapor begins to condense into liquid water.

Their relationship is: dew point reflects the absolute moisture content and is independent of temperature (under a given water vapor content), while RH changes significantly with air temperature (the same amount of water vapor will result in lower RH at higher temperatures). Therefore, in many control/monitoring applications, dew point is more stable and intuitive in indicating the moisture content of the air than RH.

Industrial compressed air and gas systems can be directly damaged due to water contamination or subsequent freezing and expansion of water. The presence of water vapor in the air or gas can also affect process or product quality. It is common practice to remove water contamination through filters and drying systems, but due to the dew point (and potential destructive condensation) varying with pressure changes, the risk of damage to the entire factory can also differ.

Dew point is typically measured using a dew point sensor or hygrometer. There are several methods to measure dew point, including: Chilled Mirror Hygrometer, Capacitive Hygrometer, Resistive Hygrometer, Infrared (IR) Hygrometer, Psychrometric Charts, Electronic Sensors.
