VI.
Wind Speed Sensor
a. Wind Speed sensor specifications.
Output:
4-20mA
Range:
0-110 MPH
Accuracy:
.2 MPH over the range 11 to 55 MPH
Operating Voltage:
10-36VDC
Current Draw:
Same as sensor output
Warm Up Time:
3 seconds minimum
Operating Temp:
-40° to +55°C
Size of Probe:
7” diameter x 8 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 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. The wind speed sensor or anemometer produces a sine wave voltage
signal with a frequency that changes linearly with the wind speed. The
frequency is transformed into a 4-20 mA sensor signal output.
