| Definition | Three lightweight, conical cups mounted on the cup wheel providing linearity with windspeeds up to 75m/s. Rotation speed is measured by a disk attached to the shaft cutting an infrared light beam 14 times per revolution producing pulses counted by a phototransistor. The output rate is directly proportional to wind speed. It was replaced by the WAA151 model which introduced a number of improvements such as plug-and-play design, an improved mechanical shaft attachment and addition of electrical lightning protection. Both models have the same output, mounting and wiring scheme and so are totally interchangeable. |
