三、电解质类湿度传感器 电解质类湿度传感器的应用已有长久历史,特别是氯化锂湿度传感器,至今仍被广泛使用。我们以这种传感器为例加以介绍。 (一)工作原理 空气的相对湿度变化,可由湿度传感器的感湿膜敏锐地反映出来。氯化钾湿度传感器的感温度膜由氯化理和聚乙烯醇(PVA)或聚乙烯缩乙醛构成。氯化锂是吸湿剂,聚乙烯醇或聚乙烯缩乙醛是粘合
Third, the electrolyte humidity sensor Electrolyte humidity sensor has a long history of the application, especially lithium chloride humidity sensor, is still widely used. We introduce this sensor as an example. (A) Working Principle The relative humidity of the air changes, can be sensitively reflected by the humidity sensor film wetness sensor. Potassium chloride humidity sensor temperature sensing film made of chloride and polyvinyl alcohol (PVA) or polyvinyl acetal composition. Lithium chloride is a hygroscopic agent, polyvinyl alcohol or polyvinyl acetal is bonded
