Description Contact Us for Wholesales Bottom Price Review
The wind speed sensor adopts the traditional three-wind cup structure. The wind cup is made of imported ABS material with high strength and small starting wind speed. The precision signal processing unit can output various signals according to user requirements. This product has the advantages of large measuring range, good linearity, convenient observation, stable and reliable.

The wind direction sensor is a professional meteorological instrument for measuring the horizontal wind direction of the wind. The interior uses a precision angle sensor and uses a low inertia ABS wind vane to respond to the wind direction with good dynamic characteristics. When the wind direction changes, the empennage rotates through the shaft to drive the potentiometer shaft to rotate, thereby generating a varying resistance signal output at the active end of the potentiometer.

Wind Speed Sensor  Calculation Formula :

Wind Speed Sensor Calculation Formula:
1: Impulsive(0 to 5V):W =0, (f = 0),
 W =0.3+0.0877×ff≠ 0
    W: indicating value of wind speedm/s
    f:    pulse signal frequency

2: Current mode (4~20mA):
    W = (i4)×45/16
     W: indicating value of wind speedm/s
i:   current type4-20mA))

3: Voltage type(0~5V)
    W =V/5×45
     Windicating value of wind speedm/s
     :  voltage signal0-5V))

4: Voltage type(0~2.5V)
    W =V/2.5×45
    Windicating value of wind speedm/s
    Vvoltage signal0-2.5V

Wind Direction Sensor Calculation Formula:
1: Voltage type (05V output)
    D = 360°×V / 5
    D: indicating value of wind direction
    V: output-voltage(V))

2: Current type ( 420mA output )
    D=360°× ( I-4 ) / 16
    D indicating value of wind direction
    I: output-current (mA))
