Engineering hints for level measurement in bulk solids and
fluids
The following installation instructions apply for rope and rod probes for measurement in
bulk solids and fluids.
Coax probes are suitable purely for measurement in fluids. They function practically
independent of all installation conditions and can, therefore, be installed as desired.
•
Temperature conditions must be met (see page 90).
•
It is recommended that a protective cover (1) is used, in order to protect the
transmitter against direct sunlight or rain (see »Accessories« on page 77.).
Mounting location
•
Do not mount rod or rope probes in the
filling curtain (3)
•
Mount rod and rope probes away from
the wall (B) at such a distance that, in the
event of build-up on the wall, there is still
a minimum distance of 100 mm between
the probe and the build-up.
•
Mount rod and rope probes as far away
as possible from installed fittings.
"Mapping " must be carried out during
commissioning in the event of distances
< 300 mm.
•
When installing rod and rope probes in
plastic containers, the minimum
distance of
300 mm also applies to metallic parts
outside the container.
•
Rod and rope probes may not, at times,
contact metallic container walls or floors.
•
In metal containers, do not install rod
and rope probes exactly in the centre
(2).
•
Minimum distance of probe end to the
container floor (C):
– Rope probe: 150 mm
– Rod probe: 100 mm
– Coax probe: 50 mm
•
When installing outdoors, it is
recommended that you use a protective
cover (1) see »Accessories« on
page 77..
