摘要
文章中通过模拟观测场条件和利用计量检定设备进行观测试验,对不同安装方式的温度观测数据对比差值进行统计分析,结果表明:温湿度支架上的保护套管会使传感器测量值滞后于环境温度变化,当观测场环境下的温度传感器露出长度小于4 cm时,气温上升时温度数据低于环境温度,气温下降时温度数据高于环境温度.建议规范传感器安装、温度传感器探头长度应至少较保护套多4 cm.
Abstract
By simulating the conditions of the observation field and using the metrological verification equipment to carry out the observation test,a statistical analysis of the difference in the temperature observation data of different installation methods was conducted.The results show that the protective sleeve on the temperature and humidity bracket will cause the sensor measurement value to lag behind the ambient temperature change.When the exposed length of the temperature sensor in the observation field environment is less than 4 cm,the temperature data is lower than the environmental temperature when the temperature rises.When the temperature drops,the temperature data is higher than the environmental temperature.It is recommended to standardize the sensor installation,and the length of the temperature sensor probe should be at least 4 cm longer than that of the protective sleeve.
