    • 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.
