4.2 Mounting instructions
Note:
Along with the planning, our specialists will analyse the conditions of
the measurement loop to dimension the radiation source (isotope)
accordingly.
You get a "Source Sizing" document specifying the required source
activity and containing all relevant mounting information for your
measuring point.
You must follow the instructions of this "Source Sizing" document in
addition to the following mounting instructions.
The following mounting information is applicable as long as there is
nothing else specified in the "Source Sizing" document.

You can find information on protective barriers and the mounting
of the corresponding source container in the operating instructions
manual of the source container, e.g. VEGASOURCE.
You can mount the SOLITRAC 31 with the housing head upward or
downward. When the housing head is mounted downward, the hous-
ing itself is more easily accessible.
Fasten the sensor in such a way that it cannot fall out of the holder. If
necessary, provide the sensor with a support from below.
Direct the exit angle of the source container to the SOLITRAC 31.
Mount the source container as close as possible to the vessel. If there
are gaps, secure the area with a safety fence and protective grating
so that no one can reach into the dangerous area.
