FIBERTRAC 31 • Four-wire 4 … 20 mA/HART
62067-EN-211203
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 FIBERTRAC 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 FIBERTRAC 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.
You can mount the sensor on your vessel with the enclosed mounting
clamps. A number of mounting clamps come with the FIBERTRAC 31
depending on the length of the sensor.
Use a mounting clamp approx. every 450 mm (17.72 in). During
mounting, adjust the distances between the attached mounting clips.
Take note of the minimum bending radius of the sensor, which is
305 mm (12 in).

Determine the exact mounting position of one or several mounting
clamps and mark the holes.
Align the mounting positions exactly and average the distances
between the enclosed mounting clamps.
Drill appropriate holes (max. M12) for fastening the mounting
clamps.
Note:
The mounting clamps do not come with fastening screws. Use fasten-
ing elements that are appropriate for the situation in your plant.
To measure the level in very high vessels, multiple instruments can be
cascaded.
Cascading means that two or several instruments are connected
which can together cover a longer measuring range.
You can find the exact number of Secondaries in the "
Safety Manual
".
