本文介绍一种高分子结露型湿度传感器,该传感器采用新型亲水性树脂作为感温材料,选择特殊结构.其阻值在低湿状态下几乎不随湿度变化;高湿时发生突变,阻值急剧上升,具有开关特性.该传感器可广泛应用于高湿及结露状态的检测与控制,诸如录像机、摄像机等视频产品配套.
This article describes a polymer dew-type humidity sensor, the sensor uses a new hydrophilic resin as a temperature-sensitive material, select a special structure. The resistance in the low humidity state with almost no humidity changes; Rise, with switching characteristics.The sensor can be widely used in high humidity and condensation detection and control, such as video recorders, video cameras and other video products.
