产品描述

- Commodity name: DG-RRTU Self-Powered/Externally Powered Rainfall Telemetry Terminal
Measurement principle

The product features a stainless steel housing with an IP65 protection rating, offering exceptional durability and superior water- and dust‑proof performance. It is self‑powered by a built-in lithium battery and accurately calculates all rainfall parameters by detecting the switch‑state signal (reed switch) from a tipping‑bucket rain gauge. Equipped with an integrated communication module, it supports direct 4G wireless transmission, enabling fast and reliable data uploads to a server to ensure timely delivery of rainfall information, thereby providing precise data support for meteorological monitoring and hydrological analysis.

The tipping‑bucket rain gauge is an essential instrument in hydrology and meteorology, used to measure natural rainfall. It converts rainfall amounts into digital signals represented as switch‑type outputs, meeting the requirements for data transmission, processing, recording, and display. Common models include 0.2‑mm and 0.5‑mm tipping‑bucket gauges, which serve as reliable rain‑measurement sensors for long-term data collection within national hydrological and meteorological station networks. The product’s stainless‑steel housing and high ingress protection rating enable it to withstand a wide range of challenging outdoor conditions, continuously providing users with dependable rainfall data.
