Wind Speed and direction measurement 

Wind speed and direction data are needed in countless situations and activities within, for example, meteorology, aviation, industry, research and construction. Vaisala manufactures wind sensors for different needs, from low cost combined units to sophisticated fully heated sensors for extreme weather conditions.

Ultrasonic wind measurement technology

The Vaisala Ultrasonic Wind Sensor WS425 uses ultrasound to determine horizontal wind speed and direction. The measurement is based on the transit time of ultrasonic transmissions between the sensor heads, transducers, as affected by the wind. By having 3 transducers equilaterally, there are always at least 2 simultaneous readings unaffected by any possible turbulence from the instrument itself.

Mechanical technology

Combining mechanical wind speed and direction sensors, the WM30 is compact and light, rigid and affordable. Low power consumption makes it ideal also for mobile applications. While for very demanding applications Vaisala offers the WA15 Wind Set and the fully heated WA25 Wind Set, an anemometer and wind vane set with a crossarm and power supply. The WA25 Wind Set has been designed for arctic conditions. As an accessory the WAT12 Wind Transmitter converts the digital data supplied by the mechanical Vaisala wind sensors into industry standard analog current loops - one for speed, the other for direction.
