The P296 Combined Anemometer Cup & Vane Direction Sensor is used by the Walker 2050. This provides excellent accuracy in a sturdy, little package. The P1249, a standard Walker DIN 144 wind speed and direction indicator, which provides digital displays of relative wind speed and direction, is directly connected to the sensor. Additionally, 72 LEDs are used to replicate an analog display and show the direction of the wind. This sensor can be used with the Walker P1066 True Wind Interface Unit to enable true wind systems. Wind direction and speed are converted into serial digital data by the sensor. The P249 Indicator shows data for wind direction both in analog and digital formats.
