Deskripsi
The RK400-01 Tipping Bucket Rainfall Sensor adalah instrumen untuk menguji curah hujan di alam. Untuk memenuhi persyaratan pengiriman informasi, pemrosesan, perekaman, dan tampilan, jumlah curah hujan dikonversi menjadi output pulsa. Dapat digunakan secara luas di stasiun cuaca, stasiun hidrometri, pertanian & kehutanan, pertahanan & stasiun pemantauan lapangan. Ini dapat memberikan data asli untuk pencegahan banjir, sistem pasokan air, dan pengelolaan air reservoir di pabrik.
FITUR
* Ukuran ringkas untuk penggunaan mudah
* Akurasi tinggi, stabilitas yang baik
* Mesh dalam corong mencegah puing-puing seperti daun dan serangga memasuki kerja sensor hujan (mesh adalah opsional)
* Tipping bucket yang dibuat dengan baik dengan resistansi rendah
* Konstruksi baja stainless yang sangat halus
* Gelembung Horisontal di bagian bawah
* Rain collector with filter, untuk mencegah dedaunan, seperti puing-puing macet di atas lubang
* Fungsi pemanasan opsional di daerah dingin
APLIKASI
* Sistem pasokan air
* Pemantauan hidrologi
* Pemantauan bencana alam
* Penelitian agro-meteorologi
* Penelitian iklim

WORKING PROCESS
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.
