RM Young - Wind Speed
Wind Data System
Marine Wind Speed System The Wind Monitor MA is an accurate and reliable wind sensor specifically designed for the rigors of the marine environment. The wind speed sensor is a four blade helicoid propeller. Unique transducer produces a pulse signal without electrical contacts or slip rings. The wind direction sensor is a durable molded vane. Vane angle is sensed by a precision potentiometer
