MS01型硅湿敏电阻器及其应用

Preparation and application of Si hygristor of MS01 type

以硅粉为主体材料、掺入少量碱金属氧化物烧结而成的湿敏电阻器，体积小，寿命 长，抗水性好，阻值变化范围大，响应时间短，抗污染能力强，适用于农田小气候和蔬菜大 棚内湿度测量，以及仓储粮食水分的遥测，还适合在加湿器或一般湿度检测与控制电路中作 抗恶劣环境的感湿探头．

The hygristor was made by Si powder doped with small amount of alkalis oxides. It has small volume, long life, good water resistance, large range of resistanc e, short response time and strong noise proof feature. Not only can it be used t o measure moisture of farm microclimate and plastic bigbox, remote d etection of grain temperature in storage, but also can be used as humidity de tector of humidifying apparatus and general electric circuit of detecting and co ntroling of temperature in mal-condition.
