Project Planning
Nivocompact FTC 231
and FTC 331
a) The correct distance from the silo
wall, the material filling curtain and
the material outlet.
For pneumatic filling systems, the
distance of the probe from the wall
should not be too small as the probe
may swing against it.
Silo Roof
Ensure that the silo roof is strong
enough!
Very high tensile forces, up to
100.000 N (10 t) may occur at the
material outlet especially with heavy,
powdery bulk materials which tend to
form build-up.
b) The probe can be damaged by the
inflowing material if mounted too near
the inlet.
When mounted near the centre of the
outlet, the high tensile forces present
at this point may damage the probe
or subject the silo roof to excessive
strain.
c) Threaded socket too long;
Condensation and dust may
penetrate and cause errors.
d) Too near silo wall;
When swinging gently the probe can
hit the wall or touch any build-up
which may have formed.
This can result in error switching
Coarse Grained Materials
The Nivocompact FTC 231 or FTC 331
should only be used for maximum
detection in silos with very coarse or
abrasive material.
Distance between Probes
A minimum distance of 0.5 m between
probes must be maintained to ensure
that there is no mutual interference;
This also applies to all Nivocompact
units which are mounted next to one
another in silos with non-conducting
walls.
