Vaisala Ultrasonic Wind Sensor WM80 for wind turbine control

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.
