Operating Instructions
Wind Sensors PROFESSIONAL-IX 3.0
Masts or tubes (grounded) suitable for mounting have an outer
diameter of Ø 48-50 mm. A mast adapter (see accessories)
is necessary.
Mounting of the adapter at the wind sensor:
1. Remove both thread nuts from the sensor.
2. Insert the sensor into the bore (Ø 30 mm) of the adapter.
3. Fasten the sensor with the fl at side of a detached nut from
the lower side. Tighten with a suitable tool (wrench size
36), until a twisting safety of the sensor is given.
Mounting of the wind sensor at the mast:
1. Install the cable with plug connection inside the mast.
2. Connect the cable with the sensor and screw down the
locking nut of the cable gland.
3. Put the sensor on the mast (tube). With regard to the wind
direction sensor the north mark on the sensor must be
aligned to the geographical north direction acc. to 2.6.4.
Afterwards fasten the locking screw in the mast adapter
to give the sensor a fi xed and torsion-free fi t.
Proceed analogously when mounting the sensor on a tube
traverse.
2.6.2 Mounting on traverse with slotted bore
hole
At each end of the traverse (Id-No. 32.14567.010 000) there
are slotted bores with a diameter of 30 mm.
1. Remove the lower nut from the sensor.
2. Put a sensor with assembled cable sidewise into the
bore.
3. Fasten the sensor with the fl at side of the detached nut
from the lower side. Tighten with a suitable tool (wrench
size 36), until a twisting safety of the sensor is given.
2.6.3 Mounting on traverse with 30 mm-bore
hole
Material thickness for installation of the sensor between the
nuts may be max. 10 mm. Mounting is to be made in the fol-
lowing steps:
1. Remove the lower thread nut from the sensor.
2. The sensor has to be inserted into the bore and fastened
by the opposite side with the loose nut (removed as under 1.).
With regard to the wind direction sensor the north mark
on the sensor must be aligned to the geographical north
direction acc. to 2.6.4 before fi nally fastening the nut.

2.6.4 North alignment of wind vane
For wind direction measurements the north mark on the sen-
sor must be aligned to the geographical north direction.
To set up the sensor's north orientation select a landmark
which is as far as possible up north with regard to the fi nal
position of the wind direction sensor.
The reference point can be selected using a topographical
map (1:25000). The exact position of the reference point is
determined using an amplitude compass that can be adjusted
horizontally on a stand.
You have to turn the wind vane's marking exactly over the
marking at the sensor shaft. When you have aligned the
marks, you may fi x the wind vane with e.g. a piece of adhesive
tape. When you have fi xed the wind vane you can locate the
reference point by aiming at it over the axis. Now you must
turn the sensor casing on the mounting tube until the tip of the
wind vane points to the reference point in the north.
This requires that the sensor is easily turnable on the mount-
ing part. The sensor has to be fi xed in this position.
Forceful turning of the mounted sensor can
damage the instrument!
After alignment the adhesive tape has to be removed.
For precise north alignment compass declina-
tion have to be considered!
Note: Follow all safety instructions while setting up
the sensor onto a mast.
