Product Details 产品规格书下载

Mechanically robust and with a chemical and condensed waterproof sensing area, the digital IST AG HYT 939 humidity module excels with the special robust construction withstanding peak loading at high temperatures. The HYT 939 is also ideal for high pressure applications and is also offered with a pressure tight packaging. Precisely calibrated, the HYT 939 delivers an accuracy of ±1.8 % RH and ±0.2 °C and combines the advantages of a precise, capacitive polymer humidity sensor with the high integration density and functionality of an ASIC. The digital software integrated in the module processes the measured data and delivers the physical parameters of relative humidity and temperature over the I²C compatible interface as digital values. The HYT 939 humidity module is therefore fully interchangeable without adjustment and both the linearity error as well as temperature drift are corrected “on-chip” through computation resulting in an outstanding accuracy over a wide range of applications. 

Further advantages of the HYT 939 digital humidity module include:

  • Calibrated and temperature compensated
  • Excellent humidity/temperature accuracy and stability
  • High chemical resistance
  • I2C protocol (address 0x28 or alternative address)
  • Wide humidity and temperature range (0 % RH to 100 % RH and -40 °C to +125 °C)
  • Very low drift
  • Very stable at high humidity
  • Interchangeable without adjustments
  • Pressure-resistant version (up to 16 bar) upon request

The digital HYT 939 humidity module is suitable for various medical systems, autoclaves, pressure dew point measurement (pressure tight packaging required), drying systems and laboratory applications.
