ELEMENT:
Pacific Data Model WS-100/WD-100 Wind speed/direction sensors
AIM:
The wind speed and direction sensors are designed to be used in conjunction
with the Datataker. The wind speed sensor responds to air velocity. The
wind direction meter measures the direction that the air is flowing. The
sensors draw their power from and then deliver the information to the
Datataker.
SRATEGY:
The sensors are installed on a 500mm cross arm on the roof. The sensors
are made from corrosion-resistant materials and are finished in matt white
polyurethane to withstand being exposed to the weather. The high position
of the sensors means that they receive as true a reading of the prevailing
wind conditions as possible.
