The YOUNG Model 27106T Gill Propeller Anemometer (CFT) utilizes a fast response helicoid propeller and high quality tach-generator transducer to produce a DC voltage that is linearly proportional to air velocity. Airflow from any direction may be measured, however, the propeller responds only to the component of the air flow which is parallel to its axis of rotation. Off-axis response closely approximates a cosine curve with appropriate polarity. With perpendicular air flow the propeller will not rotate. The output signal is suitable for a wide range of signal translators and data logging devices. The Model 27106T utilizes a carbon fiber thermoplastic (CFT) propeller for greater range and durability.
The YOUNG Model 27106DT Gill Propeller Anemometer (CFT) is a modified version of the Model 27106T. It utilizes an optical encoder to produce a square wave, pulsed output, with frequency proportional to wind speed.
