Upgraded Weather Transmitter from Vaisala


Vaisala introduces a new version of the weather transmitter, the Vaisala Weather Transmitter WXT520. The WXT520 measures wind speed and direction, liquid precipitation, barometric pressure, temperature and relative humidity – all in one instrument.

The wind speed and direction measurement is based on the ultrasonic Vaisala WINDCAP® Sensor, which ensures accurate readings from any horizontal wind direction without blind angles and corrupted readings. Barometric pressure, temperature, and humidity measurements are combined in one separate module using capacitive measurement for each parameter. The module can be changed without any contact with the internal sensors.

The precipitation measurement in the WXT520 is unique as it measures accumulated rainfall, rain intensity and duration, all in real time. It is based on the maintenance-free Vaisala RAINCAP® sensor that gives more detailed information on precipitation compared to traditional precipitation gauges.

The WXT520 housing with the mounting kit is water resistant and classified as IP66. The transmitter has a new interface card that fulfills the more demanding EMC/ESD requirements in the Marine IEC60945 standard. The WXT520 complies with the EMC standard EN61326-1; Industrial Environment. The transmitter is ROHS compliant.

A number of optional features are offered for the WXT520, for example, heating, a bird spike kit, a USB connection, and a new surge protector. The wind and rain sensors can be equipped with heating to improve the availability of correct measurement data also in severe weather conditions. The bird spike kit helps to deter birds from the WXT520. The USB connection facilitates the connection to a PC as a service connector, or when the PC is used as a terminal device. The Vaisala Surge Protector WSP152 is designed to protect the host PC against surges that may be entering through the USB port.

The power consumption of the WXT520 is very low; it can use solar panels as an energy source.

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.
