    Tips: 4-20mA output signal conversion calculation for 3-cup anemometer.

    When the 3-cup anemometer range is 0~30 m/s and the output is 4~20mA, if the output signal is 12mA, how to calculate the current wind speed value?

    The span of this wind speed range is 30m/s, expressed by 16mA current signal,
    30 m/s ÷ 16mA = 1.875/mA, that is, a current of 1mA represents a wind speed change of 1.875m/s.

    The measured value is 12mA - 4mA = 8mA. 8mA*1.875m/s /mA = 15m/s. The current wind speed is 15m/s. The calculation formula is:

    Wind speed = 1.875*current - 7.5, current value unit is mA.

    Portable 3-cup anemometer
    Fast shopping and packaging are superior. This is a portable and economical method when you need to know the actual wind speed in order to operate the equipment outdoors safely. Anyone who uses an aerial lift or crane should have a 3-cup anemometer.
