3.2 Principle of operation
Area of application
8 VEGAVIB 67 - with transistor output
VEGAVIB 67 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.
29297-EN-060508
Product description
Typical applications are overfill and dry run protection. Thanks
to its simple and robust measuring system, VEGAVIB 67 is
virtually unaffected by the chemical and physical properties of
the solid.
It functions even when exposed to strong external vibration or
changing products.
Solid detection in water
If VEGAVIB 67 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 67 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 67 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 output transistor blocks (safe condition).
Physical principle
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.
Power supply
VEGAVIB 67 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).
29297-EN-060508
VEGAVIB 67 - with transistor output 9
Product description
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 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 Mounting
4.1 General
Mounting
Switching point
Moisture
Transport
In general, VEGAVIB 67 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 67 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 67 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.
29297-EN-060508
VEGAVIB 67 - with transistor output 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
Agitators and fluidization
Inflowing material
Agitators, equipment vibration, etc., can cause the level switch
to be subjected to strong lateral forces. For this reason, do not
use an overly long extension tube for VEGAVIB 67, 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. from fluidization,
can cause the extension tube of VEGAVIB 67 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 or guy directly above the tuning fork
to secure the extension tube.
This measure applies particularly to applications in Ex areas.
Make sure that the tube is not subjected to bending forces
through this measure.
If VEGAVIB 67 is mounted in the filling stream, unwanted
switching signals may be generated. Mount VEGAVIB 67 at a
location in the vessel where no disturbing influence from e.g.
filling openings, agitators etc. can occur.
This applies particularly to instrument types with long
extension tube.

Fig. 3: Inflowing material
Mounting
Lock fitting
Socket
Material cone
VEGAVIB 67 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 is mainly applicable for
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 tuning fork detects an average value of the
material cone.
The tuning fork must be mounted at a location 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.

Connect the power supply acc. to the following diagrams. Take
note of the general installation regulations. As a rule, connect
VEGAVIB 67 to vessel ground (PA), or in case of plastic
vessels, to the next ground potential. On the side of the
instrument 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 67 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.

Set up
Switching point adaptation (1)
Mode adjustment (2)
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 67 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 67 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 transistor output. You can set the
required mode according to the "Function chart" (max.-max.
detection
overfill protection, min.-min. detection or dry run
or
protection).
We recommend connecting according to the quiescent current
principle (transistor blocks when the switching point is
reached) because the transistor output takes on the same
(safe) condition if a failure is detected.
