Wind Sensors PROFESSIONAL-IX 3.0
1 Introduction
PROFESSIONAL-IX is a very robust, compact and extremely
reliable wind sensor. The system is specially designed for use
under extremely low temperatures.
PROFESSIONAL-IX represents the experience of LAMBRECHT
in development and production of wind sensors of more than
150 years.
The system acquires the horizontal air
fl
ow and processes
the measured data into the meteorological parameters wind
speed or wind direction.
All measuring parts and the other system components are
integrated in the sealed, water-proof housing.
The PROFESSIONAL-IX wind sensor is particularly designed
for use under extreme climate conditions. The 125 watt-
heating of the sensor head allows the operation of the sensor
within a wide temperature range of -40 to +70 °C.

Setting to work
The wind can be represented by a vector quantity. For a
complete description of the wind it is necessary to specify
its speed and direction. The two components are subject to
spatial and temporal variations, thus, strictly speaking, they
are valid only for the site where the measuring instrument is
installed. Therefore, we recommend to select the place of
installation very carefully.
2.1 Installation
conditions
2.1.1 Generally
Generally, wind measuring instruments should not measure
the speci
fi
c wind conditions of a limited area, but indicate the
typical wind conditions of a wider terrain. The values measured
at different places must be comparable. Thus, when installing
the sensor you should make sure that the place of installation
is not under the lee of great obstacles. The distance between
the obstacles and the sensor should be 10 times the height
of the obstacles (this corresponds to the de
fi
nition of an un-
disturbed terrain).
If an
undisturbed terrain
of this kind does not exist the sensor
must be put up at a height of at least 5 m above the obstacle
height. If the sensor is installed on a roof top the place of instal-
lation must be in the middle of the roof to avoid predominant
wind directions. If you want to measure both wind direction
and wind speed, the sensors should be installed at the same
measuring point and any mutual influence of the sensors
should be avoided. The sensor pair PROFESSIONAL-IX with
its arrangement of sensors next to each other easily meets
this requirement.
The sensor must not be installed onto transmitting
plants or antennas or close to them. A minimum
distance of 2 m is to be kept for interference-free
signal transfer.
2.2
Tools and installation aids
There are no special tools or materials required for the instal-
lation and maintenance works. All works can be carried out
with standard tools available in the specialized trade.
2.3
Unpacking the sensor
The sensor is packed in a separate box, carefully protected
against mechanical in
fl
uences during the transport.
Please verify that the following parts and documents are
enclosed:
· 1 sensor PROFESSIONAL-IX 3.0
· 1 operating manual
Accessories:
(in accordance with the order separately packed)
Connecting cable with plug
2.4 Goods
inspection
Please verify in detail the delivery with regard to completeness
and eventual transport damages. In case of eventual claims
please contact us in writing immediately.
2.5 Power
supply
The sensor requires a 24 volt nominal DC power source
(20…28 V
DC
) for operation. The heater of the PROFESSION-
AL-IX has to be supplied with 24 volt DC and has a power
consumption of 125 W.
2.6 Installation
Attention! The installation takes place in a dangerous
height; the assembly personnel must therefore follow
the safety regulations.
2.6.1 Mast or pipe mounting
Make sure the device is easily accessible so that you
can set up the north direction for the wind direction
sensor and perform eventual maintenance works.
For access to the sensors use a ladder of the appro-
priate length or a telescope working platform of the
appropriate height, if applicable.
Ladders or other lifting helps must be absolutely
in order and must be guarantee a secure support!
Follow the rules for prevention of accidents.
