Crossarm Length: 40 cm (15.7 in) between instruments (center-to-
center)
Mounting Diameter: 34 mm (1.34 in), mounts on standard 1 inch IPS pipe
7. Installation
If you are programming your datalogger with Short Cut , skip Section 7.3 ,
Wiring
(p. 11)
, and Section 7.4 , Programming
(p. 13)
. Short Cut does this work for
you. See Section 4 , QuickStart
(p. 2)
, for a Short Cut tutorial.
7.1 Siting
Locate wind sensors away from obstructions (e.g., trees and buildings). As a
general rule of thumb, there should be a horizontal distance of at least ten times
the height of the obstruction between the wind set and the obstruction. If it is
necessary to mount the sensors on the roof of a building, the height of the
sensors above the roof, should be at least 1.5 times the height of the building.
See Section 10 , References
(p. 16)
, for a list of references that discuss siting wind
speed and direction sensors.
