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.
