摘要
为掌握目前气象行业使用的湿敏电容湿度传感器的测量准确度、迟滞误差、温度系数等测量特性,文章对3种不同型号的湿度传感器进行了测试,对不同温度点下传感器的相对湿度测量示值误差和迟滞误差进行了分析和比较,测试和分析结果表明不同传感器的温度和迟滞特性有较大的差异。其分析比较的结果对湿度传感器的选择和使用具有参考价值。
In order to understand measuring characteristics of capacitive humidity sensor such as accuracy, hysteresis and temperature coefficient, this paper tests three different capacitive humidity sensors. The errors of measurement value and hysteresis are compared under different temperature conditions. The results indicate that there are quite differences on temperature and hysteresis among these three sensors, which is available for the choice and use of capacitive humidity sensors.
