Gill WindSonic
The Gill WindSonic is a low-cost anemometer, which utilises Gill’s proven
ultrasonic technology to provide wind speed and direction data via one
serial or two analogue outputs. To confirm correct operation, outputs are
transmitted together with an instrument status code.
With a robust, corrosion-free polycarbonate housing, this small, lightweight
wind sensor is recommended for use in harsh environmental conditions and
is particularly suited to marine & offshore (ships, data buoys) and land based
installations. The WindSonic has no moving parts, offering maintenance-free
operation in a wide range of applications. This sensor is an option for the PVmet 500.
The wind speed sensor is a four blade helicoid propeller. Propeller rotation produces an AC sine wave voltage signal with frequency directly proportional to wind speed. Slip rings and brushes are eliminated for increased reliability. The wind direction sensor is a rugged yet lightweight vane with a sufficiently low aspect ratio to assure good fidelity in fluctuating wind conditions. Vane angle is sensed by a precision potentiometer housed in a sealed chamber. With a known excitation voltage applied to the potentiometer, the output voltage is directly proportional to vane angle. A mounting orientation ring assures correct realignment of the wind direction reference when the instrument is removed for maintenance.
The mini aervane utilizes an internal, contact free magnetic system that provides constant horizontal wind tracking, leaving no mechanical parts to wear out over time and require replacement. Sturdy construction can withstand the most aggressive conditions from - 40o ~ 140o F. Each sensor is individually tested before shipping and comes with a Best-in-Industry 2 year warranty. This wind sensor is included in the PVmet 200 and PVmet 330. The sensor is an option for the PVmet 500.
