Wind Direction Sensor

The "smart" WD2 Wind Direction Sensor by ICT International overcomes the "deadband" problem associated with conventional potentiometer type wind direction sensors.It does this by utilising a design that incorporates a continuous rotation type, microprocessor-controlled sensor to provide an accurate angular reading of the wind direction.This type of sensor provides the dual advantage of eliminating 'deadband' errors while minimising friction within the sensor to give an extremely low starting threshold. The WD2 sensor does not require re-initialisation after power loss as it can instantly identify bearing to an accuracy of better than +/- 0.5^o.

Advanced functionality

ICT's WD2 Wind Direction Sensor provides a single output of angle for wind direction, while the WD3 version provides dual outputs for sine and cosine of wind angle. Both sensors can provide a 24-hour standard deviation output which can be logged by the SL5 Smart Logger. The WD4 version displays angle information and computes the sigma theta directly within the sensor ready for logging by the Smart Logger. This sensor can also provide average wind direction based on a range of user-selectable periods. The "smart" WDx range of sensors can be used with any data logger and can also be linked to a variety of electromechanical and electronic counters. However, their capability is greatest when operated with an ICT International Smart Logger.
