Project Planning
The Nivocompact FTC 831 can be installed in silos made of different
materials (e.g. metal, plastic, concrete).
Note the angle of material flow or the outlet funnel when determining the
measuring point.
The Nivocompact switches (also with bulk solids with very small dielectric
constants) when the probe end is covered by a few centimetres of material
or when the material drops a few centimetres below the probe end.
The filling curtain should not be directed onto the probe.
The minimum distance of 500 mm between the probe ends of two
Nivocompact FTC 831 instruments must be maintained to ensure that there
is no mutual interference, this also applies to all FTC 831 probes which are
mounted next to one another in silos with non-conducting walls.
The distance from the probe end of an FTC 831 to the probe end of an
FTC 731 must also be at least 500 mm.
The distance from the probe end of a Nivocompact FTC 831 to the silo wall
or to any material build-up must be at least 200 mm. To ensure that no error
switching occurs when the probe swings slightly, the distance of the probe
to the silo wall should be correspondingly greater, especially with
pneumatic conveying systems.
With minimum detection, take note of the maximum load of the rope and the
strength of the silo roof.
Very high tensile forces may occur at the material outlet especially with
heavy powdery bulk materials which tend to form build-up.
These forces are significantly greater in the middle of the silo over the
material discharge point than at the silo walls.
The protective sun cover available as an accessory protects the
Nivocompact with the aluminium housing from excessive temperature and
from condensation which may form in the housing due to large temperature
variations.
