The following parts are included in the scope of delivery:

1 x Wind transmitter.

1 x Connection plug.

1 x Instructions for use.

2 Application

The wind transmitter is intended for use in the wind energy, meteorology and environmental

measuring technology. Primarily developed for position evaluation and measurement of power

curves of wind turbines, the anemometer gathers the following measured variables:

•Horizontal component of the wind velocity.

•Absolute and relative air pressure.

•Inclination angle between the Z-axis and the vertical.

•Inclination angle between the X-axis and the horizontal.

•Inclination angle between the Y-axis and the horizontal.

•Frequency and acceleration in the X-, Y- and Z-axis.

•Housing interior temperature.

Further characteristics include a defined and optimized dynamic behavior even at highly in-

tense turbulences, minimal over speeding, a low starting value and an optimized oblique inflow

behavior.

An integrated compensation of the effect of the air density on the rotation velocity of the cup

star distinguishes this sensor especially in its characteristics.

There is a digital interface to the device in form of an RS485 interface in half-duplex mode.

Together with the ID-based communication, the interface enables the operation of the wind

transmitter in a bus. Tow data protocols are available:

•ASCII (THIES format).

•Binary (MODBUS-RTU).

For operation in winter, the device can be equipped optionally with an electronically controlled

heater which provides a hardly measurable friction moment of the ball bearings in low temper-

atures and prevents any ice build-up on shaft and on the gap.

3 Setup and Mode of Operation

The wind transmitter can be supplied with direct voltages from 3.7V up to 42V at very low

power consumption. All of the electronics is a streamlined, low power design. Supply of the

optional heater is provided separately with a direct or alternate voltage of 24V. The heater

will most probably prevent icing/clogging of the wind transmitter First Class even under ex-

treme meteorological conditions.

The external parts of the device are made from corrosion resistant anodized aluminum.

Highly efficient labyrinth seals and O-rings protect the sensitive parts on the inside of the de-

vice from humidity and dust influences. It is assembled on a mast pipe, the electric connec-

tion is in the lower part of the sensor.

Wind Velocity:

A cup star with ball bearing and low inertia and 3 cups from carbon fiber reinforced plastic is

rotated by the wind. The velocity is sensed opto-electronically, translated into a square signal

with frequency proportional to the velocity and measured 4 times per second. The measured

frequency is converted into a wind velocity with the standard curve. An adaptation of this

standard curve can be done with calibration values from a programmable calibration table

(Standard curve and calibration tables).

The compensation depending on the air pressure which is calculated with the help of the cali-

bration table.

All corrected wind velocity values are available as instantaneous values. The Instantaneous

value is the gliding mean value of the last second.

For the calculation of mean value, gust, minimum value, standard deviation and intensity of

turbulence the source can be selected by the command „MS“.

The following figures show the described connection.

Instantaneous value:

The instantaneous value is the gliding mean value of the last second. The scanning of the

measuring values is carried out every 0.25s, and is not alterable. The measuring value, que-

ried at any time, includes always the data of the last second measured in the moment of

query.

Note:

From firmware version V02.09, is the interval of the gliding mean value one

second. All older versions work with an interval of 3 seconds.

Mean value:

The mean value is the gliding mean value of the last ‚n‘ seconds. ‚n‘ is defined by the param-

eter MI.

Minimum:

The minimum specifies the minimum instantaneous value of the last minute.

Gust:

The gust is the maximum instantaneous value of the last minute.

Air pressure:

A highly precise digital pressure sensor (piezoresistive) is used to measure the absolute air

pressure. The wind transmitter calculates the relative air pressure with the set altitude (com-

mand SH).

Note: The absolute air pressure is used for application of the wind velocity compensation by

means of air pressure. Indicating the sensor height by parameter SH is not required.

Inner Housing temperature:

An integrated, digital temperature sensor measures the internal temperature of the housing.

Inclination/vibration:

The measurement of the acceleration in space is done via a 3-axis acceleration sensor. The

wind transmitter will calculate the inclination angle and vibrations (frequency and accelera-

tion).

The inclination measurement is basing on the measurement of the acceleration of gravity.

The three sensitive axes of the sensor are sensitive each only in one direction, thus only that

value of the gravity acceleration is measured which affects in direction of these axes. The

slope of the sensor in space is calculated from these three measuring values.

The angle ρis defined as angle between the x-axis (north – south axis), and the horizontal.

The angle Φis defined as angle between the y-axis (west – east axis), and the horizontal.

The angle θis the angle between the z-axis, and the vertical.

Based on the angle, frequency and acceleration (amplitude), a qualified mast monitoring is

possible.

Frequency output:

In the pre-setting the incorrected pulse values of the sensor are delivered on the frequency

output. It behaves according to 4.3351.x0.000. The behavior of the frequency output is set by

parameter FO.

Intensity of turbulence:

The intensity of turbulence is calculated from the instantaneous

values of the wind velocity.

SD: Standard deviation wind velocity

xi: instantaneous value wind velocity

/x: mean value wind velocity

T: Intensity of turbulence
