Technical Description

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; an optional fast response version (damping ratio 0.4) is available on special order.
