Marine
Wind Monitor

Model 05106

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 housed in a sealed chamber. All materials are carefully selected for corrosion resistance and maximum durability in the harsh marine environment. Stainless steel bearings are used throughout. Special waterproof lubricant further enhances reliability. The instrument mounts on standard 1 inch pipe. Separate signal conditioning circuits are available to provide voltage or current signals when needed (see below). Each is supplied in a weatherproof junction box with mounting hardware.
