Wind Direction Sensor

Environdata Wind Direction Sensor

Environdata's WD50 Series wind direction sensors are accurate and robust, providing a variable pulse rate output and a visual indication of wind direction.  The use of Hall Effect sensing elements allows a full 0 to 359.9 degree range, with much greater accuracy, sensitivity and reliability than all other sensing types.

Features In Detail

Details & Advantages


The Wind Direction Vane is precision balanced and clear of the slimline sensor body which helps to minimise interfering eddies. The vane, arm and pointer turn the main spindle, which is supported by two low friction stainless steel bearings. The above features enhance the sensitivity of the instrument which will respond to changes in wind direction at ultra-low wind speeds.


The sensor signal is a robust frequency (pulses) generated by Hall Effect sensors mounted near to the lower end of the spindle, which provide an ideal frictionless and ultra-reliable sensing mechanism.


The spindle body is undercut to prevent ingress of moisture through the upper “O” ring. A labyrinth significantly reduces the chance of dust or moisture entering the upper bearing.


The WD50 wind direction sensor, when mounted on Environdata’s IS37 10m tilt-down (engineer rated) instrument mast, in conjunction with the WS52 Wind Speed Sensor provide a complete wind monitoring package suitable to meet EPA requirements in all states and territories of Australia (including AM-1, AM-2, AM-4 in NSW).


These sensors will allow you to meet the Australian Standards AS3580.14 when sited in accordance with the same standard. When used as part of an Environdata weather station our wind sensors can provide you with very accurate tracking of wind movement, including Sigma Theta calculations. Our  AirData software is for calculating the vector components of wind movement. WeatherMation LIVE Reports Module includes Wind Rose reporting for displaying a graphical summary of wind distribution over time.


The Wind Direction Vane is precision balanced and constructed from aluminium and stainless steel. As the air movement pushes the tail of the sensor, it aligns the pointer into the wind. The spindle is supported by two precision engineered low torque, stainless steel low-friction bearings, which results in low starting threshold, and excellent wind direction accuracy.
