El anemómetro de hélice 27106T es un sensor de velocidad de viento de precisión de bajo umbral especialmente diseñado para medir la componente vertical del viento. Se conecta directamente al datalogger Campbell Scientific, que mide la señal de salida del 27106T y la convierte a unidades de ingeniería (mph, m/s, knots).
Leer másThe 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 rotate.

The 27106T is shipped with a 3/4 inch IPS threaded pipe for mounting. The pipe can be attached to a CM202, CM202SS, CM203, CM204, CM204SS, or CM206 crossarm using a 1049 Nu-Rail fitting or CM220 Right-Angle Mounting Bracket.
The 27106T includes a connector/coupler that mates to the sensor and to the 3/4-inch IPS threaded pipe. The customer specified length of cable is soldered to the pins on the connector and the cable threads through the coupler and out the pipe.
