Static Weather Sensor EOLOS-IND

1 Introduction
The sensors of the EOLOS family are very robust, compact
and extremely reliable. When developing these sensors
particular consideration has been given to highest quality for
fulllment of meteorological requirements.
The sensors embody the experience of more than 150 years
of development and production of Lambrecht sensors.
The system acquires the horizontal air ow and processes
the measuring data to the meteorological parameters wind
speed and wind direction. Furthermore the weather-module of
the EOLOS-IND acquires the meteorological parameters air
temperature, relative humidity and barometric pressure. Based
on the measured data EOLOS-IND calculates the dew point
temperature and provides for its serial output along with the
measuring data.
EOLOS-IND disposes of a pulse input point for connecting the
LAMBRECHT precipitation sensors (15189).
The sensors and further system components are mounted in
a splash water- and dust proof metal housing.
The measuring data are automatically transmitted via se-
rial interface RS-422 in talker mode, when power supply is
switched on.
Due to their shock- and vibration proof construction the sen-
sor EOLOS-IND is particularly qualied for use under severe
environmental conditions. The housing is made of anodized
seawater resistant aluminium.
An electronically controlled heating device enables the sen-
sor to operate in between the wide range of -40 up to 70 °C.
1.1 Warranty advices
Please note the loss of warranty and non-liability by unau-
thorised manipulation of the system. You need a written
permission of the LAMBRECHT meteo GmbH for changes
of system components. These activities must be operated
by a qualied technician.
The warranty does not cover:
1. Mechanical damages caused by external impacts (e. g.
icefall, rockfall, vandalism).
2. Impacts or damages caused by over-voltages or elec-
tromagnetic elds which are beyond the standards and
specications in the technical data.
3. Damages caused by improper handling, e. g. by wrong
tools, incorrect installation, incorrect electrical installation
(false polarity) etc.
4. Damages which are caused by using the device beyond
the specied operation conditions.
1.2 Advantages of the static measuring principle
The sensor EOLOS-IND is a modern system to carry out pre-
cise and reliable measurements under hardest application and
environmental conditions. The wind measurements take place
according to the principle “TAV“ (thermal aura eld variation),
i. e. static, without moving parts.
Static measuring principle for wind measurements means:
• Determination of data works without moving measuring
elements, i.e. none abrasion, least maintenance and none
recalibration because of this method.
• The wind parameter can be measured also in winter time
accurate and precise, because of the electronic controlled
heating for the immovable measuring elements. This
heating is particularly e󰀨ective against ice and snow in all
climatic zones.
• Lightweight mass and immovable measuring elements to
enable very low starting values, distance- and attenuation
constants as well as a very high repetition accuracy.
• The sensor rapidly can be installed. Due to the special
measuring principle minor changes from the angle of pitch
can be disregarded.
Advantages of the sensor:
• Apart from the sensors for wind speed and direction the
compact housing also contains built-in sensors for air
temperature, relative humidity and barometric pressure.
• EOLOS-IND o󰀨ers connectivity for Lambrecht precipitation
sensors (15189)
• The built-in test function of the station, enabled by the
tight integration of the meteorological sensors into the
enclosure, can perform cyclic self-testing and notify the
user of erroneous data or failure.
• The compact design of this sensor with 5 meteorological
parameters is eliminating the traditional cabling and instal-
lation work signicantly. Distribution boxes, power supply
units and other accessories can be reduced to a minimum
expense.
2 Setting to work
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. We
therefore recommend selecting the place of installation very
carefully.
2.1 Installation conditions
2.1.1 Generally
For professional wind measurements according to meteoro-
logical standards (e. g. VDI 3786, Part 2) location and height
of the wind sensor are important for representative and ac-
curate results. Generally, wind measuring instruments should
not measure the specic wind conditions of a limited area,
but indicate the typical wind conditions of a wider area. To
obtain results which are representative for a wider area and
comparable to values measured at di󰀨erent places, the sen-
sor must not be mounted under the lee of higher obstacles.
The distance to any obstacle should be at least 10 times the
obstacle‘s height (corresponding to the denition of an undis-
turbed area). In general a measuring height of 10 m above
ground is regarded ideal.

2.5.1 Power input
The power input of the EOLOS reaches its peak in the start-up
period (activation phase). The maximum of the power input
is 2.5 A. In normal operation the average power input is sig-
nicantly lower (see table). The power input mainly depends
on the ow rate.
Wind speed Ø Power input
0 m/s 500 mA
5 m/s 650 mA
20 m/s 900 mA
38 m/s 1100 mA
Measured at supply voltage of 24 V DC and 20 °C (without heating)
2.5.2 Protection
Generally it is not necessary to protect the secondary side
(24 V DC) of the EOLOS. Normally only the primary side has
to be protected. Nevertheless if the supply should be protected
especially we recommend using a micro-fuse 3.15 A - medium
time-lag.
2.6 Installation procedure (short instruction)
The installation of the sensor involves 3 steps:
(1) Mounting the cable at the sensor and if necessary
draw the cable through the mast.
(2) Mounting the sensor at the mast, but before
tightening the screws you must align the sensor to
the north.
(3) Attaching the cable to the power supply and the
signal acquisition system.
2.7 Mounting
The sensor can be installed on a standard pipe with an outer
diameter of 50 mm and an inner diameter of maximum 40 mm.
Before tightening the two 8 mm-socket screws and attaching
the sensor you have to draw the cable through the pipe and
align the sensor into driving direction.
For this purpose the housing is marked accordingly (see draw-
ing). Before the screws of the sensor are tightened, the sensor
is adjusted to north. Please pay attention to a rm mounting
of the sensor at the mast!
In addition the sensor has a pin for the north direction. You can
put this pin into the nick at the mast (if available). If needed
you can turn in or unscrew the pin by means of allen key.
2.7.1 North alignment of wind sensor
For wind direction measurements the north mark on the sen-
sor must be aligned with the geographical north direction.
To adjust the wind sensor in a rm and correct manner into
the north direction this item is equipped with an integrated
mounting aid. Inside the inner bottom of the sensor a small bolt
pointing to the north is integrated to be set into a correspond-
ing slot of the mounting pipe (if available). Thus the sensor is
safely attached. If needed you can turn in or unscrew the pin
by means of allen key.
If an undisturbed terrain of this kind does not exist the sen-
sor have to be put up at an height of at least 6 m above the
obstacle height.
If the above mentioned requirements are not feasible e. g. on
mobile measurements at vehicles or at measuring containers
compromises have to be found and documented.
If the sensor must be 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, it is recommended to mount both sensors
at the same spot, where any interaction between the sensors
should be avoided. The sensor EOLOS-IND easily meets this
requirement.
The place of installation should not be in the
operation elds of radar devices (radar scanners
or radar transmitters), generators or antennas. We
recommend a minimum distance of 2 m to these
installations. Furthermore a minimum distance of
5 m to MF-/ HF- and Satcom- (e. g. Inmatsat, VSat)
antennas has to be kept. The maximum electric eld
intensity may not exceed 10 V/m (tested according to
EMC standard). When indicated a greater distance
should be kept.
To avoid possible measurement errors due to heat sources as
hot or warm fumes, hot surfaces etc. next to the sensor, the
mounting site should be chosen accordingly.
2.2 Tools and installation aids
There are no special tools or materials required for the instal-
lation works. All work can be carried out with standard tools
available in a regular workshop.
2.3 Unpacking the sensor
The sensor is packed in a separate box, carefully protected
against mechanical inuences during transport.
Please verify that the following parts and documents are
enclosed:
· 1 sensor EOLOS-IND
· 1 operating manual
Accessories: (depend on order size, in all cases separately
packed)
Connecting cable with plug and core cable ends
2.4 Goods inspection
Please thoroughly check the delivery with regard to complete-
ness and eventual transport damages. In case of eventual
claims please contact us in writing immediately.
2.5 Power supply
The sensor requires at the input connector a 24 V nominal
DC power source for operation. The sensor-heating has to
be supplied with 24 V DC and has a power consumption of
70 W (max. 3 A).

(1643) EOLOS-IND Manual
To set up the sensor’s north orientation select a land-
mark which is as far as possible up north with regard
to the 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.
Compass declination has to be considered!
To align the sensor ahead (on ships) locate a point outside
the ship in the landscape which is located in the ship ahead
direction respectively in the centre line or in case of the sen-
sor is mounted far away from the middle line a line parallel to
the centre line.
Once the sensor is adjusted, it can be xed with the two hex-
agonal screws. Finally the earth screw has to be connected to
the ship’s ground. Acid-free contact grease is recommended
to protect contact surfaces against corrosion.
Note: Follow all safety instructions while setting up
the sensor onto a mast.
2.7.2 Power and signal connection
The EOLOS-IND sensor requires a 12-pole bayonet plug con-
nector. The cable shield should be connected with both ends
at the ground wire (PE).
To reduce the risk of inductive interference the sensor
must be properly grounded (screening on both sides).
The external connection is via central connector which is
located in housing base. For further details about electrical
connection please see chapter “Connecting diagrams“.
If the sensor is mounted in correct manner and connected
with the right cable (accessory), you can attach the wires to
power supply and signal outputs to data acquisition equipment
(computer).
The typical power supply requirements of the EOLOS-IND
sensor are 24 Volts with a maximum current drain of 2.5 A.
The input range is max. 18... 32 V DC. The heater of the
EOLOS-IND is to supplied with 24 V DC and has a heating
power of 70 W (max. 3 A).
The serial digital output of the sensor uses di󰀨erential line
drivers with high common mode noise rejection. The sig-
nal levels and timings conform to the requirements of EIA/
RS-422 / Talker. The line drivers are capable of transmitting
data over cable lengths up to 1,220 meters (4,000 feet). This
maximum distance will vary depending upon the ope-rational
environment, the wire gauge used, and the baud- rate of the
attached devices.
When the power supply of the sensor is switched on, after
30 seconds (in order to reach operating temperature) the
sensor cyclically starts sending data protocols.
2.7.3 Safety regulations
Because the sensor often is mounted on exposed
locations in dangerous heights the installation per-
sonnel has to pay attention to the relevant safety
regulations for such works. During the electrical
installation and termination works the external circuit-
breaker must be switched o.
It is not permitted to open those housings by unau-
thorized persons!
3 Maintenance
3.1 Regular maintenance and calibration
The sensor EOLOS-IND is service reduced and designed for
a very long lifetime. Recommended is a regular visual check
regarding dirt of surface caused by the weather and if so, to
clean up.
If reference measurements should be necessary
stringently must be noted that a comparability of the
measured values is given only if the measurements
take place under same conditions. I.e. the reference
equipment must be used very close to the sensor!
The sensor is a measuring instrument and thus apply user
specic standards regarding period of recalibration.
Recommendation: 2 years.
We recommend to have the lter cap of the humidity-tem-
perature sensor every two years exchanged in our plant.
Depending on the application shorter maintenance cycles
could be necessary.
3.2 Visual check and cleaning
The use of the sensor under the respective environmental
conditions requires certain steps. It is thus recommendable
to clean the outside of the housing and shelter within specic
intervals. The intervals are dependant on the environmental
conditions and the degree of soiling. We recommend a regular
sight and functional check.

Important! Please note:
Field length
The development of a NMEA decoder should not be pro-
ceeded from rm eld lengths. The NMEA denition proceeds
from a variable eld length. The comma character (“,”) serves
as eld disconnecting switch. Numeric values in a eld can be
presented di󰀨erently. In case a eld is not sent, it has a length
of 0 characters (,,) [comma-comma].
Check sum
The check sum “CS” is covered to two ASCII characters
hexadecimal value. “CS” calculated by XOR operation of each
character in the sentence between “$” and “*”, but excluding
“$” and “*”.
Error code
In case, that the sensor cannot generate a measuring value
because e.g. a sensor element is defect or implausible (raw)
values are collected the sensor outputs in the corresponding
data protocol the above mentioned error code (e.g. 999.9) and
sets the status from “A” (valid) to “V” (not valid).
Example: $WIMWV,999.9,R,999.9,M,V*0E<CR><LF>
Particular characteristics wind direction value
Theoretically the value for the wind direction can take any
value between 0.0° and 360.0°. It should be noted, that in a
full circle the values “0.0” and “360.0” are describing the same
direction. According to the international valid recommenda-
tions of the WMO (World Meteorological Organization) in the
“Guide to Meteorological Instruments and Methods of Obser-
vation” (WMO-No.8) the wind direction value 0.0° just has to
be output at calm. The EOLOS follows the recommendation of
the WMO and outputs at wind from the north the value “360.0”
respectively “0.0” at calm (lull).
