JD05A型雨量傳感器
用途及使用范圍
本傳感器主要使用于水文﹑氣象雨量自動(dòng)測報(bào)系統(tǒng)中，適合長期遙測或自記雨量觀測，適用于年平均降雨量大于800mm地區(qū)的雨量站。

主要技術(shù)指標(biāo)
1﹑承水口徑：200mm
2﹑分辨力：0.5mm
3﹑測量降雨強(qiáng)度：≤8mm/min
4﹑測量：±4% 

結(jié)構(gòu)及工作原理
儀器為單翻斗結(jié)構(gòu)，將其水平安置于工作點(diǎn)，江水由環(huán)口控制集雨面積，集水匯集進(jìn)入翻斗部件上的小漏斗，漏斗中設(shè)置一虹吸部件，控制流入翻斗的水流強(qiáng)度，翻斗翻轉(zhuǎn)時(shí)帶動(dòng)磁鋼吸合舌簧管發(fā)出一個(gè)通斷信號傳給記錄發(fā)訊系統(tǒng)。整機(jī)采用有色合金﹑不銹鋼及工程塑料制作，完適應(yīng)野外惡劣的氣候環(huán)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.
