It can be mounted directly on the sensor arm of the Automatic Weather Station 2700, and can also be deployed on a Data Buoy Sensor Ring. This sensor consists of a wind vane on top of a magnetically-coupled compass. The compass consists of a sensing element mounted on an electronic card. In the sensing element is a follower magnet which follows the magnet on the wind vane. Four Hall elements measure the direction every second and a micro controller on the electronic card calculates the average direction in the measuring period. When direction is to be read, the compass will read out the average reading since the last reading was taken. The housing bearing the compass must be orientated towards North or to a reference point like a ship's centre-line for an ordinary degree indication. A non-averaging version (3590B) is also available. The 3590 has a measurement range of 0 to 360 degrees magnetic and requires a threshold wind speed of 0.3 m/s. It has an accuracy +/- 5 degrees and an operating temperature from -40 to +65 degC."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1778" ; skos:note "accepted"@en ; skos:prefLabel "Aanderaa 3590 wind direction sensor"@en ; skos:related , .
