通过分析SL3-1型双翻斗式雨量传感器和DSC-1型称重式雨量传感器在不同降雨强度中的降水差异,表明在夏季降水过程雨量大于30.000 mm时两种传感器的差异较小,10.000~30.000 mm的次之,当降水小于10.000 mm且有微量降水时产生差异较大。分析其原因,一方面是由于传感器感应原理不同,另一方面是传感器最小分辨率不同。
By analyzing the difference of precipitation in different rainfall intensities between SL3-1 double-tipping bucket type rainfall sensor and DSC-1 type weighing rainfall sensor, it shows that the difference between the two sensors is small when the rainfall is more than 30.000 mm in summer, 30.000 mm second, when the precipitation is less than 10.000 mm and there is a slight difference when precipitation. Analysis of the reasons, on the one hand due to different sensor sensing principle, on the other hand is the smallest sensor resolution.
