P14 Thermo
Capacitive Humidity- and
Temperature Sensor

1/2

Product
The P14 Thermo was designed especially for applications in dew point applications and humidity generators. The
favourable one chip solution consists of a capacitive humidity sensor, based on the famous P14 sensor, together
with a heating element which is also a valid Pt100 or Pt1000 sensor, at the same time. The achieved outstanding
measurement accuracy due to optimal thermal coupling makes your application top of the edge in the industry.

Advantages
Measure comfortably also at dew point
Humidity and temperature sensor on one chip
Outstanding accuracy due to optimal thermal coupling
High chemical resistance
Condensation resistant – fast recovering time after dewing,
and at high dew point temperatures as well
Wide temperature operating range
