The Walker 2050 uses a Combined Anemometer Cup & Vane Direction Sensor, the P296. This gives high accuracy in a robust compact package.
The sensor of 2050 MK2 connects directly to a standard Walker DIN 144 wind speed & direction indicator, the P1249, which gives digital displays of relative wind speed & direction. Wind direction is also displayed on a simulated analog display by 72 LED´s.
True wind systems are available by using this sensor with the Walker P1066 True Wind Interface Unit. The sensor converts wind speed and direction into serial digital data. Data is displayed by the P249 Indicator in digital format and also in analog for wind direction. The instrument interfaces in NMEA 0183/RS422 to other ship systems.
