The Vaisala Weather Transmitter WXT520 revolutionises weather measurement. It offers a full set of sensors in one instrument, including humidity, precipitation and more. It enables you to easily set up a weather station. The all in one instrument WXT520 Weather Sensors measure the following:

Simple measurement for all aspects of weather
  • Wind speed and direction
  • Liquid precipitation
  • Humidity Measurement
  • Barometric pressure sensors
  • Temperature Measurement
  • Relative humidity
Compact and durable weather transmitter
The WXT520 is compact, durable, simple to install and easy to integrate.
  • As the instrument has no moving parts, it requires little to no maintenance.
  • The WXT520 provides unparalleled flexibility due to its various options, opening new possibilities for weather measurement.  
  • The WXT520 is based on Vaisala's latest sensor technology. It combines advanced design with the decades of experience in environmental measurements.

Wind Measurement with the WXT520 Weather Transmitter
The wind measurement is based on an advanced ultrasonic wind sensor, Vaisala WINDCAP® Sensor. The sensor measures both horizontal wind speed and direction using a Vaisala patented array of three equally spaced ultrasonic sensors. This design ensures accurate wind measurement from all wind directions without blind angles or corrupted readings.  

Precipitation Measurement with the WXT520 Weather Transmitter
The precipitation measurement in the WXT520 is based on the new Vaisala RAINCAP® Sensor. Compared to traditional precipitation gauges, the sensor gives more detailed information about precipitation such as  accumulated rain fall, rain intensity and duration - all in real time.  

Humidity, Barometric Pressure and Temperature Measurement
The humidity, temperature and barometric pressure measurements are based on the well known Vaisala patented Vaisala HUMICAP®, Vaisala THERMOCAP® and Vaisala BAROCAP® Sensors.
