DISCONTINUED ITEM-Replacement Model: Vaisala WXT530 Series Weather Transmitter
The Vaisala Weather Transmitter WXT520 measures barometric pressure, humidity, precipitation, temperature, and wind speed and direction.
To measure wind speed and direction, the WXT520 has the Vaisala WINDCAP®sensor that uses ultrasound to determine horizontal wind speed and direction.
The array of three equally spaced transducers on a horizontal plane is a Vaisala specific design. Barometric pressure, temperature, and humidity measurements are combined in the PTU module using capacitive measurement for each parameter. It is easy to change the module without any contact with the sensors.
The WXT520 is immune to flooding clogging, wetting, and evaporation losses in the rain measurement.
Measuring Acoustic Precipitation
The WXT520 precipitation measurement is based on the unique 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.
The WXT520 measures accumulated rainfall, rain intensity and duration of the rain — all in real time. The Vaisala RAINCAP® Sensor is the only maintenance-free precipitation sensor on the market.
