    Short Cut is available as a download on www.campbellsci.com . It is included in installations of LoggerNet, RTDAQ, or PC400. Use the following procedure to get started. 1. Open Short Cut and create a new program. 2. Double-click the data logger model. 27106T Vertical Propeller Anemometer...
  • Page 5 3. In the Available Sensors and Devices box, type 27106T. You can also locate the sensor in the Sensors > Meteorological > Wind Speed & Direction folder. Double-click 27106T Wind Speed Sensor. The units default to meters/second, which can be changed by clicking the Wind Speed box and selecting one of the other options.
  • Page 6 9. If the sensor is connected to the data logger, check the output of the sensor in the data display in LoggerNet, RTDAQ, or PC400 to make sure it is making reasonable measurements. 27106T Vertical Propeller Anemometer...

  • Page 7: Overview

    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).

    6). Short Cut does this work for you. See QuickStart (p. 2) for a Short Cut tutorial. 7.1 Wiring Connections to Campbell Scientific data loggers are given in Table 7-1 (p. 6). Table 7-1: Wire color, wire function, and data logger connection...

  • Page 9: Voltse() Instruction

    VoltSE() 7.2.1 instruction VoltSE() measurement instruction programs the data logger to measure the 27106T. VoltSE(Dest, Reps, Range, SEChan, MeasOff, SettlingTime, Integ/fnotch, Mult, Offset) For Range, use mV2500 (CR300, CR1000) or mV5000 (CR6, CR1000X, CR3000). If the anemometer will be in electrically noisy environments, use 50 Hz or 60 Hz rejection for...

  • Page 10: Siting

    Using the multiplier is not necessary when the anemometer is used in a UVW configuration with R.M. Young model 26601UVW Translator. 7.3 Siting The 27106T should be oriented with the propeller facing the predominant flow of air being measured. No obstacle should interfere with the vertical air flow from either the up or down direction.
