The wind display LED is a modern, data processing measuring and indicating instrument for
representation and serial output of the
wind direction and
wind velocity
as „
True
“ or „
Rel.
“
value on ships.
„True Wind“ is the wind, which can be observed while the ship is standing still. It is calculated
on the basis of the received data in reference to the ship’s movement and the measured
relative wind. Depending on the setting (refer to
chapters
and
as
chapter 9
for representation on the indicator), the direction of the True Wind either
corresponds to geographic North or to the direction of the ship's bow.
„Rel. Wind“ is the wind measured on the moving ship. The direction of the relative wind
corresponds to the direction of the ship’s bow.
For ships (for ex. ferries) with changing forward or backward course the reference direction
of the wind direction display can be turned by 180°.. For shifting the reference direction there
is a gate input on the back side of the display (see
chapter
The wind display LED offers a high level of reliability and flexibility, as well as optimal display
of the wind parameters.
Coloured light emitting diodes (LED’s), which permit easy readability under a wide variety of
lighting conditions and from various distances, are used for representation. The brightness is
adjustable. Two levels of brightness can be stored via an enhanced dimming function, thus
allowing quick access to individual settings for daytime and night time brightness levels.
Depending on the model, the wind display is equipped with an additional analogue interface
and a Baro transmitter. This permits connection of additional measurement transducers for
Rel. humidity and temperature. The measured values of temperature, Rel. humidity and
atmospheric pressure are displayed serially. The parameters are not displayed.
Depending on the model the wind display is equipped with a firmware for a Log/Gyro system
or with firmware for a GPS system.
