Vaisala Wind Anemometer and Wind Vane WA15

Anemometer and wind vane with crossarm and power supply With a proven track record of successful installations, the Vaisala Wind Set WA15 has earned its reputation as the industry standard in the wind sensor market. The WA15 consists of a Vaisala Anemometer WAA151, a Vaisala Wind Vane WAV151, an optional crossarm, a power supply and cabling. Features  • Long and successful track record in meteorological applications  • Low measurement starting threshold  • Conical anemometer cups provide excellent linearity  • Heated shaft prevents bearings from freezing Key Benefits • Anemometer with excellent linearity   • The WAA151 is a fast response, low-threshold anemometer. Three lightweight, conical cups mounted on the cup wheel, provide excellent linearity over the entire operating range, up to 75 m/s.  • Sensitive wind vane   • The WAV151 is a counter-balanced, low-threshold, optoelectronic wind vane. Infrared LEDs and phototransistors are mounted on six orbits on each side of a 6-bit GRAY-coded disc. Turned by the vane, the disc creates changes in the code received by the phototransistors.  • Heated bearings withstand cold weather   • Heating elements in the shaft tunnels of both the anemometer and vane keep the bearings above freezing in cold climates.
