products. These dead zones for different mediums are listed in chap-
ter "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 also be
mounted laterally. For this, adapt the rod with rod extensions or
angled segments.
To compensate for the resulting changes in signal runtime, let the
instrument determine the probe length automatically.
The determined probe length can deviate from the actual probe
length when using curved or angled segments.
If internal installations such as struts, ladders, etc. are present on the
vessel wall, the measuring probe should be mounted at least 300 mm
(11.81 in) away from the vessel wall.
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 suitably adapted with a rod extension.
To compensate for the resulting changes in signal runtime, let the
instrument determine the probe length automatically.
You can find further information in the supplementary instructions of
the rod and cable components.
For use in an autoclave, e.g. for sterilization, the SITRANS LG240 is
available as autoclaved version.
Hence you can separate the housing from the process fitting.
Under very harsh ambient conditions, the autoclavable version can be
optionally also combined with an external housing.
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.
