IST AG Thermo - Model P14 2FW - Temperature and Humidity Sensor for Dew Point Applications
From Humidity Sensors
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.
