In case of high mechanical stress (strong vibration, moving viscous media) it may
be necessary to secure the screw connection, e�g� by a screw retaining com-
pound�
Substances such as screw retaining compounds may migrate into the
medium� Make sure that they are harmless!
When using mechanical means of securing (e�g� tooth lock washer), protruding
edges must be avoided� They may cause interference reflection�
6.3 Shortening of the probe
The rod can be shortened to adapt to different tank heights�
Ensure that the probe length is never below the minimum permissible
probe length of 10 cm (L
min
)! The unit does not support probe lengths below
10 cm� If shorter probes are used, measurement errors can occur�
Proceed as follows:
► Screw the rod to the unit�
► Mark the desired length (L) on the rod� The reference point is the lower edge of
the process connection�
► Remove the rod from the unit�
► Shorten the rod�
► Remove all burrs and sharp edges�
