  • Low threshold precision air velocity sensor
  • Fast response helicoid propeller
  • Vertical air measurements

The Propeller Anemometer is a precision, single axis wind measuring instrument. The anemometer 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 does not rotate.

The output signal is suitable for a wide range of signal translators and data logging devices. The Model 27106T with carbon fiber thermoplastic (CFT) propeller offers high sensitivity and durability.
