RAINCAP^® Sensor provides maintenance-free pecipitation measurement

The precipitation measurement in the WXT510 is based on the Vaisala RAINCAP^® Sensor, which detects the impact of individual rain drops. The signals exerting from the impacts are proportional to the volume of the drops. Hence, the signal from each drop can be converted directly to the accumulated rainfall.

Compared to traditional precipitation gauges, the Vaisala RAINCAP^® Sensor gives more detailed information about precipitation. The WXT510 measures accumulated rainfall, rain intensity and duration of the rain — all in real time. Due to the measurement method, flooding, clogging as well as wetting and evaporation losses in rain measurement are eliminated.

The precipitation sensor detects the impact of individual raindrops. The voltage signals Uj resulting from the impacts are proportional to the volume of the drops Vj and therefore, the signal of each drop can be directly converted to accumulated precipitation P.

The Vaisala RAINCAP^® Sensor is also capable of distinguishing hails from raindrops. The measured hail parameters are cumulative amount of hails, hail intensity, and the duration of a hail shower.

The Vaisala RAINCAP^® Sensor is the only maintenance-free precipitation sensor on the market.
