The WA15 is designed to handle the rugged conditions of professional wind measurement. It consists of a Vaisala Anemometer WAA151, a Vaisala Wind Vane WAV151, an optional crossarm, a power supply, and cabling. Heating elements in the shaft tunnels of both the anemometer and vane keep the bearings above freezing in cold climates. WHP151 power supply provides the operating and heating power needed for WA15. The power supply, as well as the signal and power cables are available as options.
The WA25 is a fully-heated anemometer and wind vane specifically designed for the severe conditions found in the arctic. It consists of Vaisala Anemometer WAA252, Vaisala Wind Vane WAV252, an optional crossarm, a power supply, and cabling. Foil heaters, integrated into the cups and vane, prevent snow buildup and ice formation. Heating power is also supplied to the sensor shafts, bearings, and bodies to keep them free of ice and maintain aerodynamic performance.
