3.2 Principle of operation
Application area
Functional principle
VEGAWAVE 63 is a point level sensor with tuning fork 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, VEGAWAVE 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 VEGAWAVE 63 was ordered for solids detection in water, the tuning
fork is set to the density of water. In air or when immersed in water
(density: 1 g/cm³/0.036 lbs/in), VEGAWAVE 63 signals "uncovered".
Only when 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 VEGAWAVE 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.
The tuning fork is piezoelectrically energised and vibrates at its
mechanical resonance frequency of approx. 150 Hz. When the tuning
fork is submerged in the product, the vibration amplitude changes.
This change is detected by the integrated electronics module and
converted into a switching command.
Voltage supply
VEGAWAVE 63 with NAMUR electronics can be connected to
different NAMUR amplifiers depending on your requirements. The
specifications for NAMUR amplifiers are available in the "Technical
data".
The data for power supply are specified in chapter "Technical data".

3 Product description
3.3 Operation
With the factory setting, products with a density of > 0.02 g/cm³
(0.0008 lbs/in³) can be measured. The instrument can also be adapted
to products with lower density > 0.008 g/cm³ (0.0003 lbs/in³).
On the electronics module you will find the following indicating and
adjustment elements:
l Signal lamp for indication of the switching condition (yellow)
l Potentiometer for adaptation to the product density
l Mode switch to select the switching condition (reverse character-
istics)
l Simulation key
3.4 Storage and transport
Packaging
Transport
Transport inspection
Storage
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, VEGAWAVE 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 VEGAWAVE 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.
32259-EN-120418
4 Mounting
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 VEGAWAVE 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 VEGAWAVE 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 VEGAWAVE 63 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount
VEGAWAVE 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
VEGAWAVE 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 screwed
fittings. 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 fork detects an average value of the material cone.
The tuning fork 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.
