Wind Speed or Direction Calculation Formula
Wind Speed Sensor Calculation Formula:
1: Impulsive(0 to 5V):W =0, (f = 0),
W =0.3+0.0877×f(f≠ 0)
W: indicating value of wind speed(m/s))
f: pulse signal frequency)
2: Current mode (4~20mA):
W = (i-4)×45/16
W: indicating value of wind speed(m/s)
i: current type(4-20mA))
3: Voltage type(0~5V):
W =V/5×45
W: indicating value of wind speed(m/s)
V : voltage signal(0-5V))
4: Voltage type(0~2.5V):
W =V/2.5×45
W: indicating value of wind speed(m/s)
V: voltage signal(0-2.5V)
Wind Direction Sensor Calculation Formula:
1: Voltage type (0~5V output):
D = 360°×V / 5
D: indicating value of wind direction
V: output-voltage(V))
2: Current type ( 4~20mA output ):
D=360°× ( I-4 ) / 16
D indicating value of wind direction
I: output-current (mA))
