    3-Cup Anemometer Output Characteristics

    • Pulses Output

    Characteristic transfer function:

    V = 0.667*F

    (where V = wind speed (m/s), F = output frequency (Hz) )

    • Current Output

    • Voltage Output

    Characteristic transfer function:

    V = U/ (full scale voltage - zero point voltage) * 30

    (where V = wind speed (m/s), U = output voltage (V) )

    • RS-485 Output

    lf the transmission distance is over 100m, please add a 120Q terminal matching resistances on the front endand back end of bus interface respectively. See the modbus communication protocol specification.

    Tips: 0-10V output signal conversion calculation for 0-60m/s anemometer.

    3-cup anemometer wind speed range is 0~60m/s, 0-10V output. When the output signal is 5V, calculate the current wind speed value.

    The span of this wind speed range is 60m/s, expressed by a 10V voltage signal,
    60m/s ÷ 10V = 6m/s /V, that is, a voltage of 1V represents a wind speed change of 6m/s.

    The measured value is 5V - 0V = 5V. 5V*6m/s /V = 30m/s. The current wind speed is 30m/s.

    The calculation formula is:
    Wind speed = 6*voltage, the unit of voltage value is V.

    Calibration of this anemometer sensor
    Can you speak more about the calibration of this sensor?

    ATO Responded
    Our anemometer will be calibrated before delivery.
    We calibrate the wind speed sensor to detect and calibrate the output waveform of the encoder inside.
    After general calibration, the user does not need to calibrate again.
    Know wind speed
    I like this 3-cup anemometer. It is a good lightweight device. It can measure wind speed. I use it on my drone so that I can know the wind speed at any time outside.

    Recommended anemometer
    With 3-cup anemometer, I don't need to guess the wind speed all the time. It can measure wind speed very accurately. This new anemometer performs well in maintaining speed, which is worthy of recommendation.

    Great 3-cup anemometer
    I use this 3-cup anemometer to determine the wind speed to determine whether I can spray pesticides. When I first used it, I thought the wind speed was at least 10 mph, and the gusts were much higher than this. I used it to measure the wind speed. The wind speed was only 4 mph, and the gust was about 9 mph. With this information, I can spray pesticides at ease.
