Hot Selling for Industrial Rain Sensor - Meteorological anemometer wind speed sensor – Huacheng

Impulsive:
W =0; (f = 0)
W =0.3+0.0877×f（f≠ 0)
(W: indicating value of wind speed(m/s); f: pulse signal frequency)
Current mode (4~20mA):
W = (i－4)×45/16
(W: indicating value of wind speed (m/s); i: current type(4-20mA))
Voltage type(0~5V):
W =V/5×45
(W: indicating value of wind speed（m/s) ; V: voltage signal(0-5V))
Voltage type(0~2.5V):
W =V/2.5×45
(W: indicating value of wind speed(m/s); V: voltage signal (0-2.5V)

There is five-core aviation plug, whose output is at the base of the sensor. The definition of each pin’s corresponding base pin.

1. If you have equipped with our company’s weather station, please attach the sensor cable to the appropriate connector on the weather station directly.

2. If you purchase the sensor separately, the order of the wires are as followed:
R(Red): power ＋
Y(Yellow): signal output
G(Green): power —

3. Two ways of wiring method of pulse voltage and current:

wiring method of voltage and current

output of current wiring method

[2] The above description ignores transition spaces and ‘=’ character.

1. Please examine whether the package is intact or not please, and check whether the product is consistent with your selected type.
2. Be sure no power is applied before you ensure the wiring connection is errorless.
3. No alteration to factory-set components or cables.
4. Sensor is an accurate instrument. Do not separate, damage the interface of the sensor with sharp solid and corrosive liquid.
5. Please save the verification certification and Certificate of approval which may return to repair with the products.

1. If anemometer bearing is not rotating well or have a big delay. It may because the long-term use lead to foreign matters in the bearings or weather there is any remained lubricating oil. Please inject the oil from the upside of bearings or post the sensors to our company to oiling.
2. If the indicated value is 0 or out of range when use analog output. It may be cause by cable connections. Please check weather the cable connections are correct and fastness.
3. If not the above reasons, please contact with us.
