2.2 Principle of operation
Application area
Turning the housing of VEGAPULS 64 and 69
radar sensors changes the polarization of the
radar signals. This inuences the eect false
echoes have on the measured value.
The housing lock xes the orientation of the
housing with respect to the process tting.
This makes it possible to secure an optimal
measuring position once it has been found. The
housing lock can be retrotted at any time, even
during operation. It is not necessary to dismount
or electrically disconnect the sensor.
The clamp collars have dierent contours that
t the respective sensor housing. Sensors with
plastic horn antenna have a clamping diame-
ter of 40 or 42 mm depending on the device
generation. To adapt to the respective diameter,
the supplied ring is inserted between the clamp
collars.
The following illustrations show the mounting
positions for the dierent housing versions.
