Description
 

Model 05106 Wind Monitor is a robust instrument for measuring wind speed and direction in harsh environments. Built for offshore and marine use, the 05106 features special waterproof bearing lubricant and a sealed, heavy-duty cable pigtail in place of the standard junction box. The Wind Monitor's design emphasizes simplicity and lightweight construction. Thermoplastic materials offer improved resistance to corrosion from sea air environments and atmospheric pollutants.

Wind Speed
The wind speed sensor is a helicoid-shaped, four-blade propeller. Rotation of the propeller produces an AC sine wave; the frequency is directly proportional to the wind speed. The AC signal is induced in a transducer coil by a six-pole magnet mounted on the propeller shaft. The coil is located on the non-rotating central portion of the main mounting assembly, eliminating the need for slip rings and brushes.

Wind Direction
Wind direction is sensed by a potentiometer. With the precision excitation voltage from the datalogger applied to the potentiometer element, the output signal is an analog voltage directly proportional to the azimuth angle.

Construction and Mounting
Construction is of rigid UV-stabilized thermoplastic with stainless steel and anodized aluminum fittings. Propeller shaft bearings and vertical shaft bearings are stainless steel precision-grade ball bearings. The 05106 mounts directly on a 1.0 inch IPS Schedule 40 (1.32 inch O.D.) pipe.
