Viento
Anemómetros, veletas y sensores de viento ultrasónicos para medición de velocidad y dirección. Para aviación, parques eólicos y redes sinópticas.
Surface wind is described by two variables — speed and direction — and is one of the key parameters of weather observation. Measuring it well is less trivial than it seems: turbulence, nearby obstacles, and mounting height all affect how representative the data is, and in cold climates icing can stop a mechanical sensor. Reliable measurement therefore combines the right measurement principle — cups and vane, ultrasound, or lidar — with correct siting and heating.
Speed, direction, and gust data feed aeronautical METAR reports, synoptic and climatological networks, wind-farm resource assessment and operation, and the daily safety decisions of ports, roads, and railways.
Typical application areas
- Airports and civil aviation
- Synoptic and climatological weather networks
- Wind energy: resource assessment and wind-farm operation
- Maritime operations, ports, and offshore
- Road weather and traffic safety
- Defense and military aerodromes
- Automatic weather stations at remote, unattended sites
- Wind monitoring for railways and infrastructure
What makes Vaisala's WINDCAP® technology unique
WINDCAP® ultrasonic sensors determine speed and direction by measuring the transit time of ultrasound between pairs of transducers: the wind speeds up or delays each pulse depending on its component along that measurement path. With three transducers and six measurements across paths at 60°, the sensor computes the full wind vector with redundancy — no cups or vanes to spin, no moving parts, and no periodic maintenance.
- No moving parts: nothing to wear out, jam, or replace periodically
- Full compensation of temperature, humidity, and pressure effects
- Near-zero starting threshold and 250 ms response
- Redundant measurement paths for valid data even in adverse conditions
- Thermostatic heating for freezing rain and snow
- Meets the WMO-No. 8 guide and ICAO requirements
Vaisala's wind offering is not limited to a single measurement principle: it spans from the classic cup-and-vane set — still the reference in climatological networks — through compact weather transmitters with integrated ultrasonic wind to WindCube Doppler lidars for wind profiling at height. Choosing the right principle depends on the application, the site, and the maintenance regime available.
