P14 – Rapid
Capacitive Humidity Sensor

1/2

Product
Within meteorology applications, such as radio sondes and weather balloons, there is a strong need for ultrafast, stable and robust humidity sensors. Not only at normal conditions, but also under elevated environmental
constraints as extreme low temperatures, high radiation levels and under extreme condensation, the whole
sensor operation has to be granted. Such applications need fully tailored solutions, such as those provided by
the new P14 Rapid, being the sensor of choice and unifying all related specification requirements in an ideal
manner.

Advantages
Ultra-fast response time
Resistant to temperature shocks
High humidity stability
Condensation resistant
Expanded temperature operating range
