5. Overview
The 27106T measures air velocity using a fast-response, four-blade helicoid propeller that drives
a high quality tech-generator transducer. The transducer converts the propeller rotation to a DC
voltage that is linearly proportional to air velocity. The 27106T connects directly to a Campbell
Scientific data logger, which measures the 27106T signal and converts the signal to engineering
units (mph, m/s, knots).
The 27106T is manufactured by R.M. Young (Traverse City, MI) and cabled by Campbell Scientific
for use with our data loggers. The R.M. Young instruction manual includes additional information
on the operating principles, installation, and maintenance of the sensor.
Features:
l
Especially suited for monitoring vertical wind, but can be mounted to monitor the wind in
whatever direction is desired
l
Carbon-fiber thermoplastic (CFT) propeller provides greater range and durability than
other propeller anemometers offered by R.M. Young.
l
Compatible with Campbell Scientific CRBasic data loggers: CR6, CR1000X, CR800 series,
CR350 series, CR300 series, CR3000, CR1000
