WIND SENSORS TO MEET YOUR NEEDS
WMS 301: Vaisalaî‚’s WMS 301 is a compact sized
wind sensor with wind speed and direction capability
integrated into one unit. The electronic design makes
the sensor suitable for applications where low
power consumption is essential.
WAT 12: For long distances between the sensor
installations and displays (> 100 meters), Vaisalaî‚’s
WAT 12 Wind Transmitter System is the solution.
This system is comprised of the WAA 151 anemom-
eter, WAV 151 wind vane, and WAT 12 wind trans-
mitter. The sensors are fast response, low threshold,
with heated shafts for colder climates. The WAT
12 transmitter converts the wind speed and direction
data into two analog current loop signals. The power
to the sensors is also supplied through the WAT 12
unit. An ICE-free heated anemometer, WAA 251,
is recommended where there is a high risk of ice
formation.
VERSATILE AND COST-EFFECTIVE WIND
DISPLAYS
WD 20: The WD 20 Wind Display is directly compat-
ible with the above wind sensors and offers an
economic solution to display instant values of wind
speed and wind direction. Features include automatic
brightness control, on-line configuration, and
capability for desktop, panel or wall mounting.
WD 30: The WD 30 is a multi-channel wind display
for displaying and processing wind data. It provides
instantaneous, as well as time-averaged data over
two and ten minute periods. In addition to the
features listed for the WD 20, the WD 30 can be used
with up to four WAT 12 wind sensor systems.
