Designed for demanding onshore and offshore conditions, the Vaisala Ultrasonic Wind Sensor WM80 delivers world-class wind measurements that optimize performance for any wind turbine.
Enhance wind turbine efficiency and power output in a cost-efficient way with WM80.
The Ultrasonic Wind Sensor WM80 is purpose-built to bring you reliable performance and long-lasting durability to optimize wind turbine control through the full lifespan.
WM80 provides very reliable and accurate wind measurements in all weather conditions with uninterrupted wind speed and direction data, necessary for maximum power production.
WM80 has been tested to ensure it stands up to extreme conditions. It is crafted from corrosion-resistant, anodized marine-grade aluminum and it houses 11 controlled heaters allowing stable performance even in arctic environments.
It is designed using highly accelerated life test (HALT) methodology to enhance product reliability for wind turbine and maritime environments where corrosion and heavy vibration are a challenge.
Several innovations allow the WM80 to measure reliably in tough conditions. One of the innovations is the patent pending reflector design that directs and focuses the ultrasonic beam providing 5 times stronger signal compared to conventional design. This allows uninterrupted and accurate wind measurements even in heavy rain or high wind speeds up to 90 m/s.
WM80 features a compact design and fits in tight spaces. Installation is straightforward with a push-pull connector that provides a secure, stable connection while the alignment tool ensures correct device orientation, which is required for accurate wind direction information. WM80 is maintenance-free as there are no moving parts that wear, and no need for calibration.
Seamless integration adds to WM80’s ease of use. Standardized communication protocol (NMEA and Modbus serial interface) facilitates easy integration to the turbine controller.
WM80 uses patented Vaisala WINDCAP® ultrasonic wind measurement technology, which is based on more than 50 years of wind measurement expertise.
This rugged instrument builds on the patented WINDCAP® technology, with a further signal boost from the new patented reflector, resulting in a 10-fold increase in signal level compared to conventional ultrasonic sensors.
