Features of the PRO-WEA wind sensors
The PRO-WEA wind sensor pair for determining wind direction and wind speed was specially developed for use on
wind turbines.
• Improved electrostatic discharge protection for use in lightning-prone areas
• Year-round use on wind turbines in most climatic zones due to integrated, controlled heating system
• Particularly robust and durable due to reinforced axle
• The simple cable plug connection is advantageous for quick installation and when service is required

Initial 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.
Choose installation site
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. The values measured at dierent places must be comparable.
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
to the denition of an undisturbed 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 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,
if possible, and make sure to avoid any mutual inuence of the sensors. A wind sensor pair easily meets this
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 of the cup rotor and the wind vane at the sensor
The bores at the cup rotor and the wind vane are attached in such a way that they can only be installed in a certain clear
position. All 3 screws must be used to fasten the cup rotor resp. the wind vane. Thus the correct direction of rotation is
guaranteed. The necessary wrench is included in delivery.
Mounting options
Because the installation take place in a dangerous height, the assembly personal must follow the rules for
prevention of accidents.
I. TRAVERSE WITH SLOTTED BORES
(Id No.: 32.14567.010000)
The traverse has a slotted hole of Ø 30 mm at each of its two ends.
1. Remove the nut from the sensor.
2. Put a sensor with assembled cable sidewise into the bore.
3. Attach the sensor with the at side of detached nut from the lower side.
Tighten with a suitable tool (wrench size 40), until a twisting safety of the sensor aligned to the north is given.
II. MOUNTING IN BORES
The material thickness for mounting the sensor between the nuts must not exceed 10 mm.
1. Remove the thread nut from the sensor.
2. The sensor with cable-plug connection is led without cable into the bore and fastened by the opposite side with
the loose nut as under I.3.

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 dismounting the sensor. Put
further a cable loop as sensor protection against water under the sensor.
Tip: Install the sensors on ground to the traverse and align you the wind vane parallel to the traverse. You go
only then upward, in order to accordingly align the sensors with traverse under assistance of a partner on
ground.
Adjusting the wind vane to the north
For wind direction measurements the north mark on the sensor must be aligned with the geographical north
direction. You have to turn the marking exactly over the marking at the sensor shaft. When you have aligned the
marks, you may x the wind vane with e.g. a piece of adhesive tape. When you have xed the wind vane this way 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.
To set up the sensor’s north orientation select a landmark 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.
Beware of compass misdirections.
When the north direction is set up for the wind direction sensor, you can mounting it as under point “Mounting
options”. Remove any adhesive tape.
If you cannot select a northern reference point owing to local conditions, you can proceed analogously using a
reference point in the south. In this case, however, you have to make sure the north mark on the sensor does not point
to the reference point but in the opposite direction.
Electrical connection
The PRO-WEA sensors are connected to a data measuring system via the open cable end (see example “Cable
run”). 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). 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.
Please make sure the cable is protected from humidity on the side of the data processing system. Generally,
Pg sockets that use a rubber joint to prevent humidity from penetrating into the terminal box of the data
processing system provide sucient protection.
Example: Cable run by an EMC fair Pg-socket

Alternatively the lead can be laid also completely in the pipes of a mast, if the mast is accordingly prepared.
To reduce the risk of inductive interference the sensor must be properly grounded (screening on both
sides).
Heating
The sensor has an electronically controlled 18 W heating within the sensor head. The
heating is supplied together with the sensor electronics. (On request a separate supply
of the sensor electronics and the heating by a xed cable is possible.)
Under most climatological conditions the heating prevents blocking of the moving sensor parts (see illustration).
The cup rotor or the wind vane are not heated. In case of icing or formation of ice at the moving sensor element the
function is restricted for the period of icing.
Maintenance
The sensor design permits long periods of maintenance-free operation. We therefore recommend a regular visual
verication of the north setup of the wind direction sensor as well as a sensor calibration of both sensor types every
two years. With problems, which cannot solve you, do not hesitate to contact our LAMBRECHT meteo service under:
