Vaisala WXT520 and WXT530 software
The Vaisala Weather Transmitter WXT520/WXT536 measures the six most essential weather parameters in real time: barometric pressure, humidity, precipitation, temperature, and wind speed and direction.
Wind speed and direction are reported every second. Thanks to the unique Vaisala RAINCAP® Sensor, which detects the impact of individual rain drops you get precipitation intensity every ten seconds!
To measure wind speed and direction, the WXT536 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 WXT536 is immune to flooding clogging, wetting, and evaporation losses in the rain measurement.
The WXT536 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 WXT536 measures accumulated rainfall and rain intensity of the rain – all in real time.
