Airmar 220WX WeatherStation Instrument

Airmar 220WX WeatherStation Instrument

  • Ultrasonic measurement of apparent and theoretical wind speed and direction
  • Barometric pressure
  • Air and wind chill temperature
  • GPS position, speed over ground, and course over ground
  • Three-axis, solid-state compass with dynamic stabilization
  • Three-axis rate gyro supplies rate-of–turn data
  • Three-axis accelerometer for best-in-class pitch and roll information
  • Housing IPX6 rated for water-ingress protection
  • Data output via a single cable (various lengths available)
    • NMEA 0183/ASCII serial data protocol over RS-232 interface
    • NMEA 2000® protocol over CAN

The model 220WX is Airmar’s solution for commercial-fishing weather-monitoring applications. Feature rich in a durable, rugged, small footprint that is IPX6 rated, the 220WX calculates the theoretical wind speed and direction based upon the apparent wind, speed of the vessel, and vessel heading.

The 220WX has an internal 10 Hz GPS and three-axis electronic compass. These sensors give 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 three-axis rate gyro also enhances the rate-of-turn data.
