Vaisala DRYCAP® Sensors for Industrial Dewpoint Monitoring

Stable and reliable polymer sensors have been used in relative humidity measurement for decades. In 1997, the Vaisala DRYCAP® Sensor was introduced - a new type of dewpoint sensor combining the proven characteristics of polymer sensors with a far wider operating range. Vaisala DRYCAP® products can be used in very dry environments, and in temperatures up to 350 °C.

Vaisala has taken its proven polymer technology, developed almost 30 years ago for environmental measurements, and incorporated it into the Vaisala DRYCAP® Sensor. The operating parameters have been expanded to cover industrial applications where moisture content is a critical process measurement. These demanding applications may involve high temperature zones, low dewpoints, aggressive gases, heavy particulate contamination, or all of the above.

A number of application areas

Vaisala's dewpoint transmitters have numerous industrial applications that benefit from the sensor's long-term stability and proven performance. This list includes industrial processes such as food, paper, wood, pharmaceutical, and plastics manufacturing, as well as measurements in instrument and compressed air.
