The WSD1 - Wind Speed and Direction sensor
The wind speed sensor consists of a low-inertia ABS cup assembly for fast response mounted on a dual ballrace-supported stainless steel shaft. The wind direction component of the sensor consists of a dynamically balanced wind vane operating a triple ballrace supported shaft and micro-torque potentiometer. The WSD1 produces a contact-closure pulse signal output, which means that most modern data capture units are compatible with these sensors with little or no interfacing. The benefit of this is precise and accurate measurements in all environments.
