A dew point sensor for compressed air measures the temperature at which moisture begins to condense. Keeping this value low is essential to avoid corrosion, contamination, and equipment damage.

Capacitive dew point sensors are widely used because they are accurate, fast, robust, and cost effective. They work by detecting changes in electrical capacitance as water vapor interacts with the sensor surface. These changes allow the sensor to calculate the dew point of the compressed air.

Capacitive sensors offer several advantages. They provide reliable accuracy, fast response times, and long term stability even in harsh industrial environments. They are also far more affordable than chilled mirror systems and suitable for many industries such as manufacturing, pharmaceuticals, food and beverage, and automotive.

Monitoring dew point is essential to protect equipment, maintain product quality, and ensure efficient operation of compressed air systems.

Overall, capacitive dew point sensors are key tools for maintaining dry and clean compressed air across a wide range of industrial applications.
