The black outer jacket of the cable is Santoprene ® rubber. This
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.
NOTE
4.3. Installation
4.3.1 Siting
Locate wind sensors away from obstructions (e.g. trees and building). As a
general rule of thumb there should be a horizontal distance of at least ten times
the height of the obstruction between the windset 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 8
of original 034B manual for a list of references that discuss siting
wind speed and direction sensors.
4.3.2 Assembly and Mounting
Tools Required:
• 1/2” open end wrench (for CM220)
• 5/64” and 1/16” Allen wrenches
• compass and declination angle for the site
• small screw driver provided with datalogger
• UV resistant cable ties
• small pair of diagonal-cutting pliers
• 6 - 10” torpedo level
The wind vane tail must be attached to the hub. Install the tail assembly with
the tail vertical. After tightening the set screw in the side of the hub that
fastens the tail, cover the set screw hole with one of the small round labels
included with the 034B. One of these labels is already installed on the hub
covering the set screw that attaches the hub to the sensor. Extra labels are
included with the 034B to recover the holes if the sensor has to be
disassembled for maintenance.
