HYT 939 Hermetically Sealed Digital Humidity Sensor
HYT 939 has a welded, hermetically sealed TO 39 housing with glass grommet and sinter filter designed for compressed air systems up to 16 bar. Due to the humidity calibration process and special polynomial correction method, a high accuracy of ±0.1% rH is achieved in the the low humidity region of 0-10% rH up to 50 ppm water content. The sensor is suitable for dew point measurements up to -40C dp, such as for the evaluation of medical compressed air quality.
