Product details

P14 Rapid - Optimal for weather balloons and radio sondes

Stable and robust humidity sensors with ultra-fast response time are often required in applications involving meteorology – not only in normal conditions, but also under elevated environmental constraints such as extremely low temperatures, high radiation levels and under extreme condensation. Such applications need fully tailored solutions, such as those provided by the Innovative Sensor Technology IST AG P14 Rapid. The P14 Rapid humidity sensor combines speed and full range operation in an ideal way. The sensor is capable of measuring 0 % RH to 100 % RH (maximal dew point +85 °C) with a capacitance of 140 pF ±40 pF (wired) / 180 pF ±50 pF (SMD) (at 30 % RH and +23 °C) and operates within a temperature range of -80 °C to +150 °C.
