The Model 220WX is Airmar’s solution for commercial fishing weather monitoring applications. Feature rich, in a Durable, Rugged, Small footprint that is IPX4 or IPX6 rated; the model 220WX calculates the theoretical wind speed and direction based upon the apparent wind, speed of the vessel, and vessel heading. The Model 220WX internal 10Hz GPS and 3 axis electronic compass provide heading, position, speed over ground and course over ground functionality that is required for theoretical wind data processing and mobile applications. A 3D compass with dynamic stabilization provided by the 3-axis rate gyro also enhances the rate of turn data.
RMS—Root Mean Square, LEN—Load Equivalency Number *When the wind speed is less than 2 m/s (4.6 MPH) and/or air temperature is below 0°C (32°F), wind, temperature, and relative humidity readings will be less accurate. **Wet conditions include moisture, rain, frost, dew, snow, ice and/or sea spray in the wind channel. ***Temperature and relative humidity reports invalid during heater operation. ****Airmar has made the address claiming modifications to enable compatibility with the ISO 11783 communication protocol for the agriculture industry – that is based on the SAE J1939 protocol.
