MEASUREMENT OF AIR HUMUDITY WITH APPLY MEMBRANE SILICON ULTRASONIC DEVICES
Jacek Golebiowski
Abstract:
The devices to the measurements of relative air humidity with the membrane silicon ultrasonic sensors were presented. The temperature measurements and the determination so called dew point are especially important in the determination of relative air humidity by dew point technique. The accuracy of the dew point determination appoints the accuracy of the method. The optical and photoelectric devices are used very often to the dew point determination in the different applications of this technique. The possibility of the membrane silicon sensor with ultrasonic plate waves application to the determination of the appearance of condensed water vapour is presented in this paper. The device with the ultrasonic plate waves is shown and described. The advantages of the constructed sensor in the practical determinations of air relative humidity by dew point technique are discussed. The results of experimental date are presented.
