200-05103V Wind Monitor
Voltage Outputs (recommended cable 330-18446)

The 200-05103V 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.

The 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. Internal circuitry converts the raw signal to a linear voltage output.

The wind direction sensor is a rugged yet lightweight vane with a sufficiently low aspect ratio to assure good fidelity in fluctuating wind conditions. An orientation ring is supplied for preserving wind direction reference when the instrument is removed for maintenance. Vane position is sensed by a precision conductive plastic potentiometer located in a sealed chamber. The wind direction signal is also converted to a linear voltage output.

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 (cable sold separately). The instrument mounts on standard 1 inch pipe, outside diameter 34 mm (1.34″).
