VEGA VEGAVIB 63 - contactless electronic switch - Manual (Page 11)

The max. permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.
The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the hexagon above the thread for screwing in.
4 .2 Instructions for installation
Due to the effects of agitators, equipment vibration or similar, the level
switch can be subjected to strong lateral forces. For this reason, do not
use an overly long extension tube for VEGAVIB 63, but check if you
can mount a short level switch on the side of the vessel in horizontal
position.
Extreme vibration caused by the process or the equipment, e.g.
agitators or turbulence in the vessel, e.g. by fluidisation, can cause the
extension tube of VEGAVIB 63 to vibrate in resonance. This leads to
increased stress on the upper weld joint. Should a longer tube version
be necessary, you can provide a suitable support directly above the
vibrating element to secure the extension tube.
This measure applies mainly to applications in Ex areas. Make sure that
the tube is not subject to bending stress due to this measure.
If VEGAVIB 63 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount
VEGAVIB
63 at a position in the vessel where no disturbances, e.g.
from filling openings, agitators, etc., can occur.
This applies particularly to instrument types with long extension tube.
