EHauser
Installation in plastic containers
Please note that for rod and rope probes only with a metallic surface at the process
connection an optimal performance can be guaranteed.
When installing the probe in plastic silos, whose silo cover is also made of plastic or silos
with wood cover, the probes must either be mounted in a
≥
DN50 / 2" metallic flange, or
a metal sheet with diameter of
≥
200 mm must be mounted under the screw-in piece.
•
It is also possible to mount the probe externally on the tank wall for measuring in
Aqueous solutions. Measurement then takes place through the tank wall without
contacting the medium. If people are in the vicinity of the probe mounting location, a
plastic half pipe with a diameter of approx. 200 mm, or some other protective unit,
must be affixed externally to the probe to prevent any influences on the measurement.
•
There must not be any metallic reinforcement rings secured to the tank.
•
The wall thickness should be at Fibre-Glass Reinforced Plastic/PP < 15 mm.
•
There must be no open space between the tank wall and the probe.
Installation from the side
•
If installation from above is not possible,
the Levelflex can also be mounted from
the side.
•
In this case, always fix the rope probe
(see »Fixing rope probe« ).
•
Support coax probe if the lateral load-
bearing capacity is exceeded. Only fix
rod probes at the probe end.
•
Connect rod probe metallically with the
container wall.
