Product details

P14 2FW Thermo - Optimal for dew point applications

The IST AG P14 2FW Thermo was designed especially for dew point applications and humidity generators. The favorable one-chip solution consists of a capacitive humidity sensor, based on the standard P14 sensor, together with a heating element, which, at the same time, works as a valid Pt100 sensor. The sensor achieves outstanding measurement accuracy due to the optimal thermal coupling which enables a fast recovery time. Due to heating from the Pt100, humidity is quickly released and enables fast re-measurements after condensation. Furthermore, the Pt100 sensor heats out gases or vapors from the polymer, which might cause a drift of the humidity signal. The P14 2FW Thermo humidity sensor is capable of measuring 0 % RH to 100 % RH (maximal dew point +85 °C) with a capacitance of 150 pF ±50 pF (at 30 % RH and +23 °C) and operates within a temperature range of -50 °C to +150 °C.


Consistent with the well-known, high-quality standards in Switzerland, IST AG is certified according to ISO 9001:2015 (quality) and ISO 14001:2015 (environment).  Appropriate processes are part of our daily work. They are regularly audited and extended parallel to the growth of our company.
