WA15 Wind Set for High Performance
Wind Measurement
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.
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.
A wind-rotated chopper disc attached to the shaft of
the cup wheel cuts an infrared light beam 14 times
The WA15 is based on accurate sensors installed on a large
crossarm. It is designed for demanding wind measurement
applications.
per revolution. This generates a pulse output from the
phototransistor.
The output pulse rate is directly proportional to wind
speed (e.g. 246 Hz = 24.6 m/s). However, for the highest
accuracy, the characteristic transfer function should be
used to compensate for starting inertia.
(See technical data.)
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. The output code resolution is ±2.8°.
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.
Complete Package Available
The anemometer and vane are designed to be mounted on
Vaisala crossarms.
The WHP151 power supply provides the operating and
heating power needed for the WA15. The power supply,
as well as the signal and power cables are available as
options.
