Based on the rule of dew - point indirect measurement , the dew - point control system which consists of a dew - point controller ( single chip microprocessor application system ) and a temperature - humidity sensor can control the work time and regeneration time of a dryer 它的露點測控系統(tǒng)由露點控制器(單片機應(yīng)用系統(tǒng))和溫濕度傳感器構(gòu)成,其露點測量采用了間接測量方法。
