The 05106-LC is a marine version of R. M. Young Company's 05103 Wind Monitor; its bearings are sealed to better resist the salt and sand of the maritime environment. The 05106 measures wind speed with a helicoid-shaped, four-blade propeller. Wind direction is sensed by the orientation of the fuselage-shaped sensor body, which is connected to an internal potentiometer.Read More
The 05106 Wind Monitor-MA is made out of rigid UV-stabilized thermoplastic with stainless steel and anodized aluminum fittings. The thermoplastic material resists corrosion from sea air environments and atmospheric pollutants. It uses stainless-steel precision-grade ball bearings for the propeller shaft and vertical shaft bearings.
To make it more durable in offshore and marine applications, the 05106 has waterproof bearing lubricant and a sealed, heavy-duty cable pigtail instead of the standard junction box.
The 05106 measures wind speed with a helicoid-shaped, four-blade propeller. Rotation of the propeller produces an ac sine wave that has a frequency directly proportional to wind speed. The ac signal is induced in a transducer coil by a six-pole magnet mounted on the propeller shaft. The coil resides on the non-rotating central portion of the main mounting assembly, eliminating the need for slip rings and brushes.
Wind direction is sensed by the orientation of the fuselage-shaped sensor body, which is connected to an internal potentiometer. The datalogger applies a known precision excitation voltage to the potentiometer element. The output is an analog voltage signal directly proportional to the azimuth angle.
