Cảm biến đo gió Campbell Scientific ICEFREE3A
The 27106T Vertical Propeller Anemometer is a low threshold precision air velocity sensor that is especially suited for monitoring the vertical wind component. It connects directly to a Campbell Scientific datalogger, which measures the 27106T signal and converts the signal to engineering units (mph, m/s, knots).
Compatible with all Campbell Scientific dataloggers
Especially suited for monitoring vertical wind, but can be mounted to monitor the wind in whatever direction is desired
Carbon-fiber thermoplastic (CFT) propeller provides greater range and durability than other propeller anemometers offered by R. M. Young.
The 27106T, manufactured by R. M. Young, measures air velocity using a fast-response, four-blade helicoid propeller that drives a high quality tech-generator transducer. The transducer converts the propeller’s rotation to a DC voltage that is linearly proportional to air velocity.
The 27106T should be oriented with the propeller facing the predominant flow of air being measured. Its propeller responds only to the component of the air flow, which is parallel to the axis of its rotation. Off-axis response closely approximates a cosine curve with appropriate polarity. With perpendicular air flow, the propeller does not
