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 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.
Further advantages of the P14 2FW Thermo capacitive RH sensor include:
Fast recovery time
Heating of humidity sensor (humidity sensor and heater on one chip)
Temperature measurement on-chip
Very low drift
Wide temperature range
High humidity stability
Condensation resistance
High chemical resistance
Customer specific sensor available upon request
The IST AG P14 2FW Thermo capacitive RH sensor is available with Ni/Au-flat wire as standard configuration.
