Versions
The family of METEOROLOGY sensors includes the heatable sensors for wind speed type 14576 and wind direction
type 14566.
Measuring elements
CUP ROTOR
The three-armed cup rotor is set into rotation by the wind. The number of rotations is a measure of the wind
speed. The design features of the cup rotor, which are permanently monitored by quality management during the
manufacturing process, ensure optimum linearity.

6. This allows a point determined in the south to be targeted via the sword of the wind vane and the fastening screw
to be tightened in this position using the enclosed Allen key (4 mm).
Putting into operation
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 put up. We therefore recommend to select the place of
installation very carefully.

Thus, when installing the sensor you should make sure 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

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 must be installed on a roof top the place of installation must be in the middle of the roof
to avoid predominant wind directions.
If you want to measure both wind direction and wind speed, install the sensors at the same measuring point,

requirement since the sensors are set up side by side. Their horizontal distance should be approximately 1.5 m. The
two sensors must be staggered vertically so that the lower edge of the upper wind speed sensor is 0.1 to 0.5 m above
the upper edge of the lower wind direction sensor.
MOUNTING THE SENSOR ON THE MAST
Mount the sensor at the top of a grounded tube with an outer diameter of 50 to 52 mm. Make sure the device is easily
accessible so that you can set up the north direction for the wind direction sensor and perform any maintenance
work. To reach the sensors use a ladder of the appropriate length or a telescoping working platform of the
appropriate height.
Ladders or other lifting helps must be absolutely in order and must be guarantee a secure support!
You can also use masts that can turn around their vertical axis or masts consisting of individual segments or
telescoping masts that you can secure after setting up the north direction.
If wind speed and wind direction are measured at the same time, the measurement generally takes place not only at
the top of a mast but also at the ends of a cross arm. The arms must stay torsion-free and vibration-proof even at high
wind speeds and they must be accessible for you to perform mounting and maintenance work.
When you install the connecting cables make sure not to excessively shorten the cable leading to the connector in
the lower part of the sensor casing so that you can later maintain or dismount the sensor.

VIEW OF CABLE ROUTING ON A WIND TRAVERSE
ESTABLISH ELECTRICAL CONNECTION
All sensors of the METEOROLOGY series are electrically connected via a 12-pin connector (pin) embedded in the
base of the housing.
Because the installation takes place in a dangerous height, the assembly personal must follow the rules
for prevention of accidents.
CABLE ROUTING
The connecting cable is suitably led along the mast between the data evaluation device (indicating instrument
or data acquisition system) and the sensor. The cable must be fastened using appropriate cable ties (their length
depends on the mast diameter). You can also install the entire connecting cable within the tube elements of the mast
if the mast is prepared correspondingly.
Lead the cable in a wide curve from the mast to the bottom of the casing so that you can later easily
dismount the cable.
Example illustration:
Cable routing through an
EMC compliant Pg socket
Please make sure the cable is protected from humidity on the side of the data processing system. Generally, Pg

OUTPUT SIGNAL
When you connect the output signal please note the assignment of the wires of the open cable end shown in
the internal circuit diagrams on the following pages. The individual output wires lead you to the corresponding
connecting terminals of the data acquisition section.
ELECTRONICS SUPPLY
On models 14566 and 14576, the electronics are supplied via the J(-) and H(+) wires of the 12-pin connector.
The permissible values are:
Model Voltage Current

The electronic heating of versions 14566 and 14576 is supplied via an external power supply unit. The necessary
voltage of 24 VDC is connected via the M(-) and G(+) wires.
GROUNDING
To reduce the risk of inductive interference the sensor must be properly grounded (screening on both sides). The use
of ready-made connecting cables from LAMBRECHT meteo guarantees a proper grounding between sensor and
cable. You just have to connect the cable screening to the ground of the indicator or the data acquisition unit. When
other cables are used, you must create an appropriate screening.
ADJUSTING THE WIND VANE
For wind direction measurements the north mark on the sensor must be aligned with the geographical north
direction; the allowed maximum alignment deviation is ±3 degrees. To set up the sensor’s north orientation select

Please make sure there is no magnetic deviation of the compass.
When the north direction is set up for the wind direction sensor, tighten the headless screws in the lower part of the
casing and remove any adhesive tape, if necessary. Using an indicating instrument or a data acquisition system,

If the local conditions do not allow the reference point to be set up in a northerly direction, the procedure can be
applied analogously to a southerly reference point. In this context, it must be ensured that the north mark on the wind
sensor does not point to the reference point, but in the opposite direction.
