66076-EN-230810
Version with pneumatic switching ON/OFF
The pneumatic actuator must not be used under ambient conditions
that can cause corrosion in and on the pneumatic actuator.
4.2 Mounting instructions
For continuous level measurement the source holder must be
mounted slightly above or at the height of the max. level. The radiation
must be directed exactly towards the detector mounted on the op
-
posite side.
The source holder VEGASOURCE should be mounted as close as
possible to the vessel.
However, with large measuring ranges and small vessel diameters, a
gap can often not be avoided.
If there are gaps or empty spaces around the installation, provide
protective fences or grids to keep hands away from the dangerous
area. Such areas must be marked accordingly.

Beam angle 30° and 45°
For level detection, the version of the source container with an exit
angle of
a
= 5° is suitable. The radiation must be directed exactly
towards the detector mounted on the opposite side.
If you want to use larger exit angles (40° or 60°), you have to make
sure the beam is horizontal. To do this you have to mount the source
container so that the lugs are in a horizontal position.
The source holder VEGASOURCE should be mounted as close as
possible to the vessel.
