RK400-01D Tipping Bucket Rainfall Sensor


Sensor Curah Hujan Tipping Bucket RK400-01D adalah instrumen untuk menguji curah hujan di alam. Untuk memenuhi persyaratan transmisi, pemrosesan, perekaman, dan tampilan informasi, jumlah curah hujan diubah menjadi output pulsa. Ini dapat digunakan secara luas di stasiun cuaca, stasiun hidrometri, pertanian & kehutanan, stasiun pemantauan pertahanan & lapangan. Ini dapat memberikan data asli untuk pencegahan banjir, sistem pasokan air, dan pengelolaan air waduk di pabrik.

Working Process & Dimension

Rainfall is captured in the 200mm diameter collector funnel and is directed through a delivery pipe to fill a divided ABS injection molded tipping bucket device.The bucket is pivoted through its center and has a preset calibration to tip for 0.2 mm of rainfall. When the bucket is “full”, it pivots and empties – this action magnetically closes and opens a reed switch, sending a pulse signal to the data logger or electronic counter. Through this tipping “seesaw” action, the other side of the bucket is aligned to receive the flow from the delivery pipe. This recording and tipping cycle continues with rainfall.
