When the antenna extension is shipped with the radar sensor,
calibration is carried out beforehand in the factory. The radar sensor is
thus adapted to the antenna extension. To ensure the functioning of
the measurement, a correct assignment of the antenna extension to
the radar sensor is necessary. For this purpose the antenna parts are
marked with the serial number of the sensor.
Note:
An incorrect combination will compromise the accuracy. Make sure
that sensor and antenna extension belong together.
Electromagnetic radar signals are polarised, i.e. aligned with a certain
plane. With angled antenna extensions as well as versions with rinsing
air connection, the bending axis must be directed to this polarisation
plane. Using the markings on the sensor and the antenna parts, this
orientation is easy to carry out. These markings are listed in chapter
"Mounting steps".
In case of very long antenna extensions or heavy mechanical loads, a
mechanical load relief for the antenna system is necessary.
