3.2 Principle of operation
VEGAVIB 63 is a point level sensor with vibrating rod for level
detection.
It is designed for industrial use in all areas of process technology and
is preferably used for bulk solids.
Typical applications are overfill and dry run protection. Thanks to its
simple and robust measuring system, VEGAVIB 63 is virtually
unaffected by the chemical and physical properties of the bulk solid.
It also works when subjected to strong external vibrations or changing
products.
Solid detection in water
If VEGAVIB 63 was ordered for solid detection in water, the vibrating
rod is calibrated to the density of water. If covered by water (density:
1 g/cm³/0.036 lbs/in) VEGAVIB 63 signals "uncovered". Only if the
vibrating element is also covered with solids (e.g. sand, sludge, gravel
etc.) will the sensor signal "covered".
Fault monitoring
The electronics module of VEGAVIB 63 monitors continuously the
following criteria:
l Correct vibrating frequency
l Line break to the piezo drive
If one of these faults is detected, the electronics signals this via a
defined current to the signal conditioning instrument. The connection
cable to the vibrating element is also monitored.
Functional principle
Voltage supply
8VEGAVIB 63 • - two-wire
The vibrating rod is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx. 360 Hz. When the
vibrating rod is submerged in the product, the vibration amplitude
changes. This change is detected by the integrated electronics module
and converted into a switching command.
Depending on your requirements, VEGAVIB 63 with two-wire
electronics can be connected to different signal conditioning instruments. Compatible signal conditioning instruments are listed in chapter
"Technical data".
The data for power supply are specified in chapter "Technical data".

3.3 Operation
With the factory setting, products with a density of > 0.05 g/cm³
(0.002 lbs/in³) can be measured. It is possible to adapt the instrumentfor products with lower density > 0.02 g/cm³ (0.0007 lbs/in³).
On the electronics module you will find the following indicating and
adjustment elements:
l Signal lamp for indication of the switching condition (green/red)
l Potentiometer for adaptation to the product density
l Mode changeover for selection of the output current

Storage and transport
temperature
Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of environmentfriendly, recyclable cardboard. In addition, the sensor is provided with
a protective cover of cardboard. For special versions PE foam or PE
foil is also used. Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging. Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt. Ascertained transit damage or
concealed defects must be appropriately dealt with.
Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
l Protected against solar radiation
l Avoiding mechanical shock and vibration
l Storage and transport temperature see chapter "Supplement -
Technical data - Ambient conditions"
l Relative humidity 20 … 85 %

4.1 General instructions
Suitability for the process conditions
Switching point
Moisture
Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" and on the
type label.
In general, VEGAVIB 63 can be installed in any position. The
instrument only has to be mounted in such a way that the vibrating
element is at the height of the desired switching point.
Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.
You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain off. This
applies mainly to outdoor mounting as well as installation in areas
where high humidity is expected (e.g. through cleaning processes) or
on cooled or heated vessels.

Do not hold VEGAVIB 63 on the vibrating element. Especially with
flange and tube versions, the sensor can be damaged by the weight of
the instrument.
Remove the protective cover just before mounting.
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.
Handling
Agitators and fluidiza-
tion
Inflowing medium
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 scr ewing 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 st ream, 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.

Lock fitting
Socket
Material cone
VEGAVIB 63 can be mounted with a lock fitting for height adjustment.
Take note of the pressure information of the lock fitting.
The vibrating element should protrude into the vessel to avoid buildup.
For that reason, avoid using mounting bosses for flanges and screwedfittings. This applies particularly to use with adhesive products.
In silos for bulk solids, material cones can form and change the
switching point. Please keep this in mind when installing the sensor in
the vessel. We recommend selecting an installation location where the
vibrating rod detects an average value of the material cone.
The vibrating rod must be mounted in a way that takes the
arrangement of the filling and emptying apertures into account.
To compensate measurement errors caused by the material cone in
cylindrical vessels, the sensor must be mounted at a distance of d/6
from the vessel wall.
