Application Note
Humidity Module
HYT
3. HYT 939
Precisely calibrated, the HYT 939 delivers an accuracy
of ±1.8 % RH and ±0.2 °C. Further features are the
integrated signal processing for measuring the physical
parameters of relative humidity and temperature, the
I
2
C compatible interface, easy interchangeability without
adjustment as well as mechanical robustness, chemical
resistance, dew formation resistance and long-term
stability.
Both the linearity error and temperature drift are
corrected “OnChip” through computation. Because of
the special robust construction, the sensor also withstands
peak loading at high temperatures. Therefore, this special
model is also ideal for extremely sophisticated industrial
applications in drying systems and suitable for medical
systems.
For a pressure tight sensor packaging consult IST AG.
Typical Areas of Application:
▪ Medical systems
▪ Autoclaves
▪ Pressure dew point measurement (pressure tight
sensor packaging required)
▪ Drying systems
▪ Laboratories
