The Walker 2080 MK2 uses a Solid State Ultrasonic Wind Speed & Vane Direction Sensor, the P293. This gives high accuracy in a robust compact package… with no moving parts to wear out!
The Sensor connects directly to a standard Walker DIN 144 wind speed & direction indicator, the P249, which gives digital displays of relative wind speed & direction. Wind direction is also displayed on a simulated analogue display by 72 LEDs. True wind systems are available by using this sensor with the Walker P1066 True Wind Interface Unit.
