Humidity sensor with ultra-fast response time and decreased recovery time

Stable and robust humidity sensors with ultra-fast response time are often needed in meteorological applications  – not only under normal  but also elevated environmental conditions, such as extremely low temperatures and exposure to condensation. Our P14 4051 Rapid Thermo provides the fully tailored solutions required by such applications.

The IST AG P14 4051 Rapid 2 Thermo consists of an ultra-fast capacitive humidity sensor based on our outstanding P14 polymer and a heating element. The sensor boasts an extraordinarily fast response time (< 0.3s at 23°C) due to optimized thin film layers especially developed for meteorological applications.  

The heating function provides the possibility to protect the sensors from icing and enables fast re-measurement after condensation.

The P14 4051 Rapid 2 Thermo humidity sensor is capable of measuring 0 % RH to 100 % RH (maximal dew point +85 °C) with a capacitance of 650 pF ±150 pF (at 30 % RH and +23 °C) and operates within a temperature range of -80 °C to +150 °C.
