Cảm biến đo hướng gió Campbell Scientific 024A-L
The 024A, manufactured by Met One, is a wind vane that measures wind direction only. It can be used in tandem with the 014A Wind Speed Sensor. However, this combination has been largely replaced by the 034B, which monitors both wind speed and wind direction.
The 024A Wind Vane measures wind direction from 0 to 360 degrees with a 5 degree accuracy specification. Wind direction is sensed with a 10 kohm potentiometer. With the precision excitation voltage from the datalogger applied to the potentiometer element, the output signal is an analog voltage that is directly proportional to the azimuth of the wind direction.
The vane has a damping ratio of 0.25.
