27106T Gill Propeller Anemometer
1. General Description
The 27106T Gill Propeller Anemometer sensor is used to measure vertical
wind speed. Wind speed is measured with a helicoid-shaped, four-blade
propeller. Rotation of the propeller produces an analog voltage signal
proportional to wind speed with polarity determined by the direction of the
wind.
The R.M. Young Instruction Manual includes additional information on the
operating principles, installation and maintenance of the sensor.
Lead length for the 27106T is specified when the sensor is ordered. Table 1-1
gives the recommended lead length for mounting the sensor at the top of the
tripod/tower with a 019ALU or CM200 series crossarm.

NOTE
The black outer jacket of the cable is Santoprene
compound was chosen for its resistance to temperature extremes,
moisture, and UV degradation. However, this jacket will
support combustion in air. It is rated as slow burning when
tested according to U.L. 94 H.B. and will pass FMVSS302.
Local fire codes may preclude its use inside buildings.
