products. These blocking distances for different mediums are listed
in chapter "
Technical data
". Keep in mind for the adjustment that the
default setting for the measuring range refers to water.
The process fitting must be sealed if there is gauge or low pressure in
the vessel. Before use, check if the seal material is resistant against
the measured product and the process temperature.
The max. permissible pressure is specified in chapter "
Technical
data
" or on the type label of the sensor.
In case of difficult installation conditions, the probe can be also
mounted laterally. For this purpose, adapt the rod with rod extensions
or bow-shaped segments.
Let the probe length determine automatically by the instrument to
compensate the resulting running time changes.
The determine probe length can deviate from the actual probe length
when using bow-shaped segments.
If installations such as struts, ladders, etc. exist on the vessel wall,
then the probe should have a distance to the vessel wall of at least
300 mm (11.81 in).
You can find further information in the supplementary instructions of
the rod extension.
In case of difficult installation conditions, for example in a socket, the
probe can be adapted respectively with a rod extension.
Let the probe length determine automatically by the instrument to
compensate the resulting running time changes.
You can find further information in the supplementary instructions of
the rod extension.
For use in an autoclave, e.g. for sterilization, the VEGAFLEX 83 is
available as autoclaved version.
Hence you can separate the housing from the process fitting.
Open the slotted nut with a hook wrench and remove the housing in
an upward direction.
The side of the process fitting must be covered with a lid after the
housing is removed. Screw the enclosed lid with slotted nut onto the
instrument side of the process fitting and tighten the nut with a torque
of 20 Nm.
Make sure that no liquid or contamination penetrates into the housing
or the process side.
After autoclaving, screw the lid off again and place the housing verti-
cally on the side of the process fitting. Tighten the slotted nut with a
torque of 20 Nm.
