| 摘 要： | 通过改进湿度传感器温湿特性实验室测试方法,对国产GPS探空系统和RS92探空仪湿度传感器的温湿特性进行了测试分析.结果表明:国产电子探空仪的湿度传感器在低温状态下探测滞后性明显,给高空湿度的动态测量带来了较大误差,尤其是在低温升湿过程测量比低温降湿过程更为显著.试验还表明环境空气流量的变化会对湿度的测量造成明显的影响,结果有助于改进探空仪湿度传感器测湿算法和防雨帽工艺设计,提高高空湿度测量能力.

| Abstract: | The temperature and humidity characteristics of humidity sensor on China-made GPS and RS92 radiosounding system are studied through a modified test method under controlled temperature and humidity environment in a laboratory.The results show that hysteretic detection occurred under low temperature,especially during the process of humidity increase,which brings obvious error to the dynamic measurement of aerological humidity.The change of airflow also influences the humidity measurement.The obtained results are useful for the modification of humidity measurement algorithm of radiosounding sensor,and the improvement of the measurement performance of aerological humidity sensor. |
