Display AE402-D
The display is placed in a build-in housing 135 x 135 mm and contains the sensor interfaces,
the display-driver, the accumulators and the battery charger. The display can be supplied by
any direct voltage between 9 and 15 Volt. As long as the display is supplied with external
voltage, the accumulators will be charged. The display can also be operated with external
voltage, without containing accumulators. The operating time after recharging the
accumulators is 80 h with normal brightness of the direction LED's, switching the LED's to
bright reduces the operating time to 35 h.
When the LED's indicating m/s or kt
respectively inst. or avg. become dark, the
accumulators has to be recharged. The
display unit AE402-D shows wind direction
by a LED-ring with 36 LED's with a
resolution of 10 degrees. It shows wind
speed by a large LCD-display with 18 mm
high characters. Kt. or m/s are selectable by
a push button, instantaneous or 2 min
average can be selected by a second button.
With a third button the power can be
switched on or off. On the right side, there
is a small switch for showing the direction
LED's normal or bright.
Wind Speed Sensor W400-1 and the Wind Direction Sensor W400-2
The wind sensor W400-1 and W400-2 are
small, sensors for wind direction and wind
speed. It consists of anodised aluminium,
polyamide and stainless steel. As wind
speed sensor, it uses a tri-cup anemometer
and a reed contact output.
4 magnets give 4 impulses per revolution.
1 m/s = 4 Hz
As direction sensor, it uses a vane together
with a ring-potentiometer with 5 k-Ohms.
The sensor has a 11 m long connection
cable with plug; extension cables up to 20
m are available. To fix the sensor on the
tripod, it has an 8 mm female thread.
