Wind vanes are used to measure wind direction and are mounted at the height of the wind you are measuring. Second Wind offers a wide range of wind vanes to meet the needs of many different wind assessment projects.
Second Wind PV-1 Wind Vane
The PV-1 was developed by Second Wind in response to our customers in the field. Earlier technology too often fell short in its ability to accurately capture data in every direction and in cold, icy environments. With the PV-1, you get all the features you expect in an affordable, high-performance wind vane: simple construction, stable/smooth response to wind change and perfect balance. Price: $245.
The PV-1 is a continuous-rotation potentiometric wind direction vane featuring stainless steel and thermoplastic construction for corrosion resistance. It is ideal for applications including wind resource assessment, meteorological studies, and environmental monitoring. The mechanical range is a full 360 degrees with continuous rotation, and the instrument is compatible with all Nomad wind data loggers from Second Wind and similar data logging devices.
- Long life precision potentiometer
- 0 to 360° range, 8° open

RM Young #5103 Wind Monitor
The Model 05103 Wind Monitor is a high resolution wind speed and direction sensor. Its simplicity and lightweight corrosion resistant construction make it well suited for a wide range of wind measuring applications. Price: $945.
The RM Young Wind Monitor wind 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 not used, resulting in improved reliability and lower cost.
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 position is sensed by a precision conductive plastic potentiometer located in a sealed chamber. With a known excitation voltage applied to the potentiometer, the output signal is directly proportional to azimuth angle. An orientation ring is supplied for preserving wind direction reference when the instrument is removed for maintenance.
The instrument is made of UV stabilized plastic with stainless steel and anodized aluminum fittings. All bearings are stainless steel precision grade. Transient protection and transducer terminations are in a convenient junction box on the mounting post. The instrument mounts on standard 1" pipe.
