Überblick

Der RainVUE™️20 ist ideal für viele hydrologische oder meteorologische Anwendungen wie Wetterstationen und Hochwasserwarnsysteme. Der RainVUE™️20 ist eine SDI-12 Regenkippwaage, die erste der RainVUE Sensorfamilie. Moderne Algorithmen und digitale Signalverarbeitung im Sensor kompensieren Fehler durch hohe Regenintensitäten und bieten akkurate Niederschlagsmessungen. Durch die aerodynamische Konstruktion des Aluminium-Auffangtrichters wird der Verlust an aufgefangenem Niederschlag durch Wind minimiert. Der Kunde kann aus verschiedenen Kabellängen wählen und <!--und die Auflösung von 0.01 in. oder 0.1 mm-->.

Technische Beschreibung

The RainVUE™️20 funnels rainfall through a stainless-steel gauze filter that traps and removes debris. The rainfall flows through a nozzle into one of the two halves of the tipping bucket. The internal tipping bucket assembly rotates around precision, rolling pivot bearings, it tips when the first bucket fills to a fixed calibrated level, and then the balance arm moves the second bucket under the funnel. A magnet attached to the balance arm actuates a reed switch as the bucket tips.

The aerodynamic design of the RainVUE™️20 prevents wind from carrying the rainfall away from the collecting vessel. With traditional cylindrical rain gages, wind can reduce the rainfall catch by up to 20%. The RainVUE™️20 also includes a microprocessor that corrects for rainfall intensity and outputs an SDI-12 signal.
