摘　　要：空气湿度是气象观测中的一个重要参数。目前,气象业务工作中常用的湿度传感器有HMP45D型、HMP155A型与DHC1型温湿度传感器,为比较这三种温湿度传感器的湿度测量性能,在每种型号中各抽取3支进行比对实验,并进行分析。实验结果显示:三种湿度传感器误差曲线走向基本一致,HMP155A与DHC1型温湿度传感器湿度测量精度较高,除95%RH高湿点外,各测量点湿度误差均在±2%RH以内,而HMP45D误差绝对值则高于2%RH。Air humidity is an important meteorological parameter for meteorological observation. The HMP45D, HMP155A and DHC1 temperature and humidity sensors are used commonly in automatic weather station recently. In order to compare the humidity measurement performance of these three types of temperature and humidity sensors, three sensors of each type are selected to do experiments and its data are analyzed. The result shows that the measurement error tendency of these three types of sensors is alike. The measurement accuracy of HMP155A and DHC1 humidity sensor is higher than HMP45D humidity sensor. Apart from 95% humidity points, each point humidity measurement errors of HMP155A and DHC1 are within ±2%RH. And the absolute errors of HMP45D are more than 2%RH.
