The HYT 939 from IST Innovative Sensor Technology is a Hygrochip digital humidity and temperature module for extremely sophisticated industrial applications. HYT 939 delivers an accuracy of ±1.8 % RH and ±0.2 °C and is precisely calibrated. This module features signal processing for measuring the physical parameters of relative humidity and temperature, I2C 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 "on-chip" through computation. The sensor withstands peak loading at high temperatures because of the robust construction. HYT 939 is welded, hermetically sealed TO-39 housing with glass grommet and metal filter is designed for compressed air systems up to 16 bar.
