Wind Direction Output
When wind direction is measured, WMT700 sends analog output
as simulated potentiometer output voltage referred to as external
reference voltage. The output is a proportional signal 0 ... 100 %
of the reference voltage representing the wind direction. The
reference voltage must be in the range of 1.0 to 4.0 VDC
(WMS425) or 0…10 VDC (WMT700). The output is 0 VDC at
zero degrees and increases to the reference voltage at 359 degrees.
Figure 50 below shows the output for wind direction. With
WMT700, the wind direction signal appears at pin 13 (gray) of
the adapter cable.
