RM YOUNG - Wind Speed System

The Marine Wind Tracker has special features for shipboard use.
 
Wind speed is displayed in your choice of units: KNOTS, MPH, KM/H, M/S. Maximum wind speed is also shown. Wind direction information is clearly displayed on a circular pattern of LEDs. Bold front panel graphics give a quick indication of wind angle relative to vessel heading. Brightness control allows adjustment for best viewing in any light. Luminous front panel markings allow viewing even in a darkened pilothouse. 4-20 mA inputs, Serial NMEA, and Voltage outputs are standard on the Marine Wind Tracker. Alarms for both wind speed and wind direction are included. The Marine Wind Tracker is very compact for easy mounting on vertical bulkheads or consoles. Model 06260 Protective enclosure offers extra protection for wet or dusty locations.

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.
