Ｃ_Ｈ－ＤＲ型电容式湿度变送器的维修黄文鑫（云南大理卷烟厂大理市６７１０００）电容式湿度变送器是用介电系数随环境相对湿度大小而变化的高分子化合物作电介质。并构成电容器作湿敏元件。随着这种高分子薄膜吸收的水分量的变化。膜的介电系数将发生相应的变化，因此?..
Maintenance of C_H-DR Capacitive Humidity Transmitter Huang Wenxin (Dali Cigarette Factory, Dali 671000, China) Capacitive humidity transmitters are dielectric materials with macromolecular compounds whose dielectric constant changes with the relative humidity of environment. And constitute a capacitor for the humidity sensor. With the change in the amount of moisture absorbed by this polymer film. The dielectric constant of the film changes accordingly, so?
