3.2 Principle of operation
Area of application
8 VEGAVIB 65 - with contactless electronic switch
VEGAVIB 65 is a 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, VEGAVIB 65 is
virtually unaffected by the chemical and physical properties of
the solid.
29284-EN-060508
Product description
It functions even when exposed to strong external vibration or
changing products.
Solid detection in water
If VEGAVIB 65 was ordered for solid detection in water, the
tuning fork is to the density of water. In air or if covered by
water (density: 1 g/cm³/0.036 lbs/in) VEGAVIB 65 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 of VEGAVIB 65 continuously monitors the
following criteria:
l Correct vibrating frequency
l Line break to the piezo drive
If one of the stated malfunction is detected or in case of power
failure, the electronics takes on a defined switching condition,
i.e. the contactless electronic switch opens (safe condition).
Physical principle
Power supply
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
oscillator and converted into a switching command.
VEGAVIB 65 is a compact instrument, i.e. it can be operated
without external evaluation system. The integrated electronics
evaluates the level signal and outputs a switching signal. With
this switching signal, a connected device can be operated
directly (e.g. a warning system, a PLC, a pump etc.).
The exact range of the supply voltage is specified in the
"Technical data" in the "Supplement".
3.3 Adjustment
With the factory setting, products with a density of >0.02 g/cm³
(>0.0008 lbs/in³) can be measured. It is possible to adapt the
instrument for 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 (green/
red)
l potentiometer for adaptation to the product density
29284-EN-060508

l Mode switch for selecting the switching condition (min./
max.)
3.4 Storage and transport
Packaging
Storage and transport tem-
perature
Your instrument was protected by packaging during transport.
Its capacity to handle normals loads during transport is
assured by a test acc. to DIN 55439.
The packaging of standard instruments consists of environ-
ment-friendly, 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.
l Storage and transport temperature see "Supplement -
Technical data - Ambient conditions"
l Relative humidity 20 … 85 %

4.1 General
Mounting
Switching point
Moisture
Transport
In general, VEGAVIB 65 can be mounted in any position. The
instrument must be mounted in such a way that the vibrating
element is at the height of the requested switching point.
Use the recommended cables (see chapter "Connecting to
power supply") and tighten the cable gland.
You can give your VEGAVIB 65 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 mounting outdoors, in
areas where moisture is expected (e.g. by cleaning processes)
or on cooled or heated vessels.
Fig. 2: Measures against moisture penetration
Do not hold VEGAVIB 65 on the vibrating element. E specially
with flange and tube versions, the sensor can be damaged by
the weight of the instrument.
Remove the protective cover just before mounting.
Pressure/Vacuum
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 stated in the "Technical
data" in the "Supplement" or on the type label of the sensor.
Handling
The vibrating level switch is a measuring instrument and must
be treated accordingly. Bending the vibrating element will
destroy the instrument.
29284-EN-060508
VEGAVIB 65 - with contactless electronic switch 11
Mounting
Warning:
The housing must not be used to screw in the instrument!
Applying tightening force on the housing can damage its
internal mechanical parts.
To screw in, use the hexagon above the thread.
4.2 Mounting information
Socket
Filling opening
Horizontal installation
The vibrating element should protrude into the vessel to avoid
buildup. For that reason, avoid using mounting bosses for
flanges and screwed fittings. This is mainly applicable for
adhesive products.
Install the instrument in such a way that the tuning fork does
not protrude directly into the filling stream. Should such an
installation location be necessary, mount a suitable baffle
above or in front of the tuning fork.
If such an installation location should be necessary, mount a
suitable protective sheet above or in front of the vibrating
element - see illustration a.).
In abrasive solids, mounting according to illustration b. has
proven. A spout forms in the concave protective sheet
preventing wear of the protective sheet.
To achieve a very precise switching point, you can install
VEGAVIB 65 horizontally. However, if the switching point can
have a tolerance of a few centimeters, we recommend
mounting VEGAVIB 65 approx. 20° inclined to the vessel
bottom to avoid buildup.

Inflowing material
Flow
If VEGAVIB 65 is mounted in the filling stream, unwanted
switching signals may be generated. Mount VEGAVIB 65 at a
location in the vessel where no disturbing influence from e.g.
filling openings, agitators etc. can occur.
To minimise flow resistance caused by the tuning fork,
VEGAVIB 65 should be mounted in such a way that the
surfaces of the fork are parallel to the product movement.

Mounting
Adhesive products
Baffle protection against fall-
ing rocks
In case of horizontal mounting in adhesive products, the
surfaces of the tuning fork should be vertical in order to reduce
buildup on the tuning fork. On the screwed version you will find
a marking on the hexagon. With this, you can check the
position of the tuning fork when screwing it in. When the
hexagon touches the seal, the thread can be still turned by
approx. half a turn. This is sufficient to reach the recommended installation position.
With flange versions, the fork is directed to the flange holes.

In applications such as grit chambers or settling basins for
coarse sediments, the vibrating element must be protected
against damage with a suitable baffle.
This baffle must be manufactured by you.

l Connect only in the complete absence of line voltage
In hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the
sensors and power supply units.
Connect the power supply acc. to the following diagrams.
Oscillator VB60C is designed in protection class 1. To maintain
this protection class, it is absolutely necessary that the ground
conductor be connected to the internal ground terminal. Take
note of the general installation regulations. As a rule, connect
VEGAVIB 65 to vessel ground (PA), or in case of plastic
vessels, to the next ground potential. On the side of the
housing there is a ground terminal between the cable entries.
This connection serves to drain off electrostatic charges. In Ex
applications, the installation regulations for hazardous areas
must be given priority.
The data for power supply are stated in the "Technical data" in
the "Supplement".
VEGAVIB 65 is connected with standard cable with round
cross-section. An outer cable diameter of 5 … 9 mm
(0.2 … 0.35 in) ensures
the seal effect
of the cable entry.
If cable with a different diameter or wire cross section is used,
exchange the seal or use an appropriate cable connection.
In hazardous areas, only use approved cable connections for
VEGAVIB 65.

We recommend connecting VEGAVIB 65 in such a way that
the switching circuit is open when there is a level signal, line
break or failure (safe condition).
The contactless electronic switch is always shown in nonoperative condition.
The instrument is used for direct control of relays, contactors,
magnet valves, warning lights, horns etc. It must not be
operated without an intermediately connected load, because
29284-EN-060508

Connecting to power supply
the electronics would be destroyed if connected directly to the
mains. It is not suitable for connection to low voltage PLC
inputs.
Domestic current is temporarily lowered below 1 mA after
switching off the load so that contactors, whose holding current
is lower than the constant domestic current of the electronics,
are reliably switched off.

Signal lamp (5)
With the potentiometer you can adapt the switching point to the
solid. It is already preset and must only be modified in special
cases.
By default, the potentiometer of VEGAVIB 65 is set to
complete right position (>0.02 g/cm³ or >0.0008 lbs/in³). In
case of very light-weight solids, you have to turn the
potentiometer to the complete left position (>0.008 g/cm³ or
>0.0003 lbs/in³). Hence the VEGAVIB 65 will be more
sensitive and can detect light-weight solids more reliably.
For instruments detecting solids in water, these values are not
applicable. The potentiometer is preset and must not be
changed.
With the mode adjustment (min./max.) you can change the
switching condition of the output. You can set the required
mode acc. to the "Function chart" (max.-max. detection
protection, min.-min. detection or dry run protection).
