VII. Wind Direction Sensor
a. Wind Direction sensor specifications.
Output:
4-19 mA
Range:
0 to 360° (352° electrical, 8° open)
Accuracy:
1% of full scale
Operating Voltage:
10-36VDC
Current Draw:
Same as sensor output
Warm Up Time:
3 seconds minimum
Operating Temp:
-40° to +55°C
Size:
8 ½” diameter x 10 ½” long
Weight:
1 lb.
b. The sensor is a two-wire sensor using the red wire for power and the
black wire for the output signal. Warning: Always connect the
sensor with the power turned off.
c. The ridge on the fixed portion of the sensor represents the 0° direction
of the sensor. The sensor comes with a stainless steel elbow that can
be mounted on a 1” diameter tube. For best results ensure that the
sensor is mounted parallel to the ground surface.
d. A wind direction sensor produces a ratiometric voltage signal. That
voltage signal is transformed into a 4-19 mA sensor output signal.
