Marine-Wind Monitor

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. Ceramic bearings are used throughout. 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
