Cooling water curves The required amount of cooling water is dependent on the possible
heat transmission, the cooling water temperature and the detector
type. You find the cooling water curves and further information in
the technical specifications on page 2-241.
Connecting the water cooling Water is always supplied from the bottom to prevent air pockets
that can drastically reduce the cooling effect. Therefore, the detec-
tor has to be aligned so that the water exits at the highest point (see
illustration on page page 2-248).
2.3.2 Sun Protection
If the detector is installed outdoors, it should be protected against
exposure to direct sunlight by a weather protection roof.

2.3.3 Heavy-Duty Environments
When selecting the installation site, keep in mind that the detector
should not be affected by mechanical stress or heavy vibrations, in
order not to restrict its service life. If the measuring system is used
in a heavy-duty environment, the detector and the shielding should
be provided with an additional protective cover.
2.3.4 Precautions against Vibrations
Excessive vibrations or shocks on the detector shorten the service
life. Mount the detector on a vibration-free support; you may also
dampen possibly occurring vibrations or shocks using appropriate
vibration absorbers.
2.3.5 Magnetic Fields
The detector is provided with an internal shielding that protects the
photomultiplier against magnetic fields. Nevertheless, strong mag-
netic fields in close proximity to the detector may impair its func-
tion. In this case, the detector can be protected by an additional
thick-walled steel tube, or the measuring point has to be relocated
to another suitable position. In these cases BERTHOLD
TECHNOLOGIES would be happy to help you.
