VEGA EL 4 Conductive probe - Manual (Page 10)

4 .2 Mounting instructions
Due to agitators, equipment vibration or similar, the level switch can be
subjected to strong lateral forces.
Extreme vibration caused by the system, e.g. due to agitators or
turbulence in the vessel from fluidisation, can cause the probe of EL 4
to vibrate in resonance. If a longer rod version is necessary, you can
secure the probe by fastening a suitable isolated brace or guy directly
above the end of the rod.

If EL 4 is mounted in the filling stream, unwanted false measurement
signals can be generated. For this reason, mount EL 4 at a position in
the vessel where no disturbances, e.g. from filling openings, agitators,
etc., can occur.
This applies particularly to instrument versions with a longer probe.
