The Vaisala Weather Transmitter WXT536 measures barometric pressure, humidity, precipitation, temperature, and wind speed and direction.
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.
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
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.
