The vane, arm and pointer turn the main spindle, which is support by two low friction stainless steel bearings. The use of Hall effect sensing elements allows a full 0 to 359.9 degree range, with much greater accuracy, sensitivity & reliability than all other sensing types.

Monitoring Wind Direction for EPA licences
Satisfying Australian Standards
The WD48 wind direction sensors are sensitive wind direction indicators which give a variable pulse rate output and a visual indication of wind direction. The aluminium wind vane is attached to an aluminium arm and adjustable stainless steel pointer. The WD48 uses Hall Effect sensing to provide very accurate wind direction readings. Moreover, as there is no potentiometer, there is no ‘gap’ in the readings at north, with a full 0 to 359.9 degree range. Accuracy combined with reliability are the key to this world class wind direction sensor.
The wind vane, arm and pointer turn the main spindle, which is supported by low friction shielded bearings.
A labyrinth machined into the spindle housing prevents the entrance of wind-borne dust or moisture into the upper bearing.
Use Environdata’s IS37 10m Instrument Mast and WS49 Wind Speed sensor in conjunction with the WD48 for a complete wind monitoring package suitable to meet EPA requirements in all states and territories of Australia (Including AM-1, AM-3, AM-4 in NSW).
This system will meet the Australian Standards and when used as part of an Environdata Weather Station (by connecting to a Weather Maestro, WeatherMate 3000 or WeatherWombat data logger) can provide you with very accurate tracking of the wind, including a sigma theta calculation from the data logger, AirData Software for calculating the net movement of the air, and WindRose for displaying a graphical summary of wind distribution over time.
