Six-in-one
With the world becoming increasingly sensitive to weather and climate, it is important to measure the weather accurately. The Vaisala Weather Transmitter WXT520 offers the solution to measure barometric pressure, humidity, precipitation, temperature, and wind speed and direction - all with one instrument!

Applications
Compact and lightweight, the WXT520 is suitable for weather stations, dense networks, buildings, golf courses, marinas, harbors, and hotels - almost anywhere where real time weather data is needed. Accurate and reliable data provided to you early enough can increase safety to life and property.

How does WXT520 do it?
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, which ensures accurate wind measurement from any horizontal wind direction without blind angles and corrupted readings. 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. Precipitation measurement is based on the Vaisala RAINCAP® sensor.

Heating
The wind and rain sensors can be equipped with heating, which improves the availability of correct measurement data at all times. Heating also reduces moisture and ice forming on the surface of the tranducers. The heating circuit is independent of the operational power. The WXT520 has an automatic control circuit that switches the heating on at low Vaisala Weather Transmitter WXT520 Access to Real Time Weather Data Heating at work in a WXT520. temperatures, well before the freezing point.

Powered by the sun
As the power consumption of the WXT520 is very low, it can use solar panels as an energy source. Not only does this save energy, but also allows you to use the WXT520 in remote areas where electricity is not available.
