Vaisala launches ultrasonic wind sensor

333

Designed to withstand the challenges and wide range of conditions in both wind energy and maritime applications, the Vaisala Ultrasonic Wind Sensor WM80 brings accurate wind information to wind-turbine control, offshore vessel dynamic positioning, and navigation systems, enhancing performance and safety.

“Leaning on insights from multiple decades of experience in professional wind measurement and wind turbine technology, we understand the challenges of meeting the demanding conditions of modern wind farms,” said Matthieu Boquet, head of wind operations at Vaisala. “This innovative, robust, and compact sensor delivers highly reliable data for turbine control, helping to secure maximum power production and seamless operations. Further value creation and cost reduction can be gained when used in combination with a Nacelle-mounted lidar.”

Vaisala’s proven Windcap sensor technology uses three transducers, capturing 50 percent more wind signal compared to conventional ultrasonic technologies, to maintain measurement accuracy and reliability. The technology withstands extreme conditions while its compact design installs in tight spaces. The heated anemometer ensures stable performance, even in arctic environments.

Reliable wind direction data is crucial for achieving maximum available energy. In addition to measurement accuracy, the correct sensor alignment is critical for wind-direction data. The modular sensor design, together with the alignment tools, ensures the sensor is always aligned.

“Designed to enhance both safety and performance, our new ultrasonic wind sensor provides real-time wind information, helping to maximize operational windows and strengthen efficiencies,” said Mikko Nikkanen, head of maritime, weather and environment at Vaisala.

Key features of the Vaisala WM80 include:

  • Accurate, dependable wind data: WM80 uses a novel reflector design (patent pending) that focuses the ultrasonic signal to the transducers and maintains focus despite changing wind speeds up to 90m/s.
  • Compact design: Developed for extreme heat, icing conditions, high winds, precipitation, vibration, and shock, WM80 incorporates corrosion-resistant, anodized marine-grade aluminum in its compact form-factor.
  • Easy installation: The sensor’s design, with a push-pull connector and alignment tools, simplifies setup.
  • Zero maintenance: With no moving parts and no need for calibration, the sensor remains free from the limitations of mechanical wind sensors.
