The sensor FAR305xx is made up of a vane rotating around a vertical axis, designed to be always aligned to the wind direction. The vane is placed at the end of a counterbalanced support and it's joint to the rotating vertical axis. All the rotating group is linked on stainless steel bearings with low friction, this allows a very high sensitivity.
The Compact Weather Sensor PCTAN012 is belongs to the product family of professional intelligent measurement transducers with digital interface for environmental applications. For extreme conditions (eg. marine environments, wind turbines) it available a metal version.
The PCTAN017 is a three axis ultrasonic anemometers. It measures the speed and direction of wind, the X - Y - Z Cartesian components of speed, sound speed and sonic temperature.
