Overview

Designed for offshore and marine applications, the 05106 is a lightweight, robust instrument that measures wind speed and direction. Manufactured by R. M. Young, this wind monitor is cabled for use with Campbell Scientific data loggers.

Key Advantages

Reliable, Accurate Wind Measurements
Suitable for marine applications

Technical Description

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 data logger applies a known precision excitation voltage to the potentiometer element. The output is an analog voltage signal directly proportional to the azimuth angle.
