Version with pneumatic switching mechanism
The pneumatic actuator must not be used under ambient conditions
that can cause corrosion in and on the pneumatic actuator.
3.2 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 SHLD 1 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.
Align the source holder according to its beam exit angle.

For continuous mass flow determination the source holder must be
mounted above a conveyor belt or a discharge screw conveyor. The
radiation must be directed exactly towards the detector mounted on
the opposite side.
Mount the source holder SHLD 1 on the measuring frame (optional).
There are large spacings and gaps between measuring frame and
conveyor belt.
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.
The arrangement of the source holders depends on the width and the
loading height of the conveyor belt. In case of wide conveyor belts,
