The AV-WSD-10 combined Wind Speed and Direction sensor is manufactured from anodized aluminum alloy, UPVC, and stainless steel with moulded polypropylene cups. The units are lightweight yet very robust. The sensors are designed to be mounted to a mast of between 30…50mm diameter by means of a V-shaped clamp and bracket. This allows simple orientation to North using the compass provided; the only setup required. Wind Direction is sensed by a precision conductive potentiometer that combines exceptionally long life with high sensitivity. Wind speed is derived from a Hall Effect solid-state magnetic switch activated by magnets in the cup rotor running in the precision stainless steel ball race and ‘Oilite’ bearings giving very high sensitivity and very long life.
