JD05A型雨量传感器
用途及使用范围
本传感器主要使用于水文﹑气象雨量自动测报系统中，适合长期遥测或自记雨量观测，适用于年平均降雨量大于800mm地区的雨量站。
主要技术指标
1﹑承水口径：200mm
2﹑分辨力：0.5mm
3﹑测量降雨强度：≤8mm/min
4﹑测量：±4%
结构及工作原理
仪器为单翻斗结构，将其水平安置于工作点，江水由环口控制集雨面积，集水汇集进入翻斗部件上的小漏斗，漏斗中设置一虹吸部件，控制流入翻斗的水流强度，翻斗翻转时带动磁钢吸合舌簧管发出一个通断信号传给记录发讯系统。整机采用有色合金﹑不锈钢及工程塑料制作，完适应野外恶劣的气候环境。
Application and Use range
The sensor is used for the hydrological﹑weather rainfall automatic forecasting system mostly, suitable for long-term remote or self-recording rainfall observation, is the same with the precipitation rain fall station of the annual average rainfall more than 800 mm.
Major technological index
1. Holding water caliber: 200mm
2. Distinguish rate: 0.5mm
3. Measuring rainfall intensity: ≤8mm/min
4. Measuring precision: ±4%
Structure and Working principle
The equipment is single dump structure, level install the equipment at the work point, the river by ring mouth control rainfall area, catchment influx into the all funnel of dump parts, in the funnel set up a full orientation siphon parts, control the water flow intensity into the dump parts, when dump parts overturned drive alnico attract the tongue reed pipe issue of a on-off signal tranit to the record originating system. Whole equipment all adopt nonferrous metal alloy﹑stainless steel and engineering plastics, fully adapt to the wild bad climate and environment.
