200-05103
Wind Monitor

The 200-05103 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.

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 not used, resulting in improved reliability and lower cost. The signal is available as a raw output, voltage output or current output, depending on model chosen.

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. The signal is available as a raw output (in which case a regulated excitation voltage must be supplied by the monitoring equipment), or as a voltage output or current output, depending on model chosen.

The instrument is made of UV stabilized plastic with stainless steel and anodized aluminum fittings. All bearings are stainless steel precision grade. An orientation ring is supplied for preserving wind direction reference when the instrument is removed for maintenance. Transient protection and transducer terminations are in a convenient junction box on the mounting post (cable sold separately). The instrument mounts on a standard one-inch IPS pipe with an outside diameter of 34 mm (1.34").
