1.1 Function and configuration
VEGAVIB compact level switches are used for
level monitoring of powders and granules. The
vibrating level switches are energised
piezoelectrically and vibrate at their mechanical
frequency (VEGAVIB 31 approx. 210 Hz,
VEGAVIB 41 and 43 approx. 530 Hz, VEGAVIB
51, 52 and 53 approx. 350 Hz).
If the measured product reaches the sensor, the
vibrating amplitude is damped. An integrated
electronics detects this damping and triggers a
switching command.
VEGAVIB 31 is a tuning fork sensor and is suitable for unproblematic, fine-grained solids
> 100 g/l which do not cause buildup. Typical
products are gypsum, cement, chalk, fine granules, etc.
VEGAVIB series 40 and 50 vibrating level
switches can be used where levels of solids
with a density greater than approx. 20 g/l need
to be reliably detected. Due to the rod design, it
is almost impossible for material to build up or
get wedged in. This enables their use in foodstuffs and light solids such as e.g. packing
chips. Typical products are cement, gypsum,
chalk, flour, styrofoam, shredded paper, washing powder, plastic granules, down feathers,
packing chips etc. A pulsed actuating signal
causes the rod to begin vibrating again after
immersion and removes the measured product
from the vibrating rod.
Series 50 sensors are also suitable for the detection of solids in water.

2.1 Mounting instructions
VEGAVIB
Generally, the instruments can be mounted in
any position. The instrument must be mounted
so that the measuring system (vibrating rod) is
at the height of the requested switching point.
VEGAVIB 31, however, from below the vessel
bottom. Installation will vary depending on the
various measured products and the requirements on the measurement. You should give
consideration to the following points.
Lateral load
Make sure that the vibrating element is not
subjected to lateral forces. Mount the instrument
at a location in the vessel where no adverse
conditions, e.g. caused by stirrers, filling openings etc. can occur. This applies mainly to
instrument types with cable or extension tube
(see fig. 2.1). The surfaces of the tuning fork of
VEGAVIB 31 should be parallel to the product
movement.
Stirrers
Through the action of stirrers or similar devices,
the level switches can be subjected to strong
lateral forces. For this reason, do not use an
overly long extension tube for VEGAVIB 43 and
VEGAVIB 53, but check if it is possible to mount
instead a VEGAVIB 41 or VEGAVIB 51 level
switch on the side of the vessel in horizontal
position.
Filling opening
Mount the instrument in such a way that the
vibrating element does not protrude directly into
the filling stream. If such a mounting location is
necessary, install a suitable protective sheet
above or in front of the vibrating element, e.g.
L80 x 8 DIN 1028 (see fig. 2.2 a). Mounting acc.
to Fig. 2.2 has proven successful for measuring
abrasive solids. A product cornice grows on the
concave protective sheet and keeps it from
being abraded.
Horizontal installation
To achieve a very precise switching point,
VEGAVIB can be mounted horizontally. However
if the switching point can have a tolerance of a
few centimetres, we recommend mounting the
instruments downwardly inclined (approx. 20°)
to avoid buildup (see fig. 2.2). Mount VEGAVIB
31 in such a way that the surfaces of the tuning
fork are vertical.

The dimensions of the vibrating rod or the tuning fork should not be modified. Any change will
destroy the instrument.
Fig. 2.2
VEGAVIB 13
Page 14
Mounting
Handling
The vibrating level switch is a measuring instrument and must be treated accordingly. Bending
the vibrating element will destroy the instrument.
Lock fitting
Lock fittings are available for VEGAVIB 43 and
VEGAVIB 53 for infinitely variable height adjustment. Be aware that VEGAVIB 53 level switches
in conjunction with a lock fitting must not be
used in pressurized vessels. VEGAVIB 43 can
be used in vessels with up to 4 bar pressure.
Tensile load
When using the cable version, make sure that
the max. permissible tensile load of 6000 N is
not exceeded. This can occur mainly with very
heavy solids and large measuring lengths.
Buildup
With VEGAVIB 31, the surfaces of the tuning
fork should be vertical in order to reduce
buildup. The orientation of a tuning fork is
marked on the hexagon of VEGAVIB. With it you
can check the position of the tuning fork. When
the hexagon touches the seal, the thread can
still be turned by approx. half a turn. This is
sufficient to reach the recommended installation
position.
If the granulation size of the solid is larger than
the min. distance between the tuning fork
blades (8 mm), product particles can wedge
themselves in the tuning fork and trigger a
malfunction. In this case, series 40 or 50 vibrating level switches should be used.
Pressure
When there is gauge pressure or underpressure
in the vessel, the mounting boss must be sealed
on the thread. Cover the thread with teflon tape,
hemp or a similar material or use a sufficiently
resistant seal ring.
Fig. 2.3
Material cone
When planning the location of the vibrating rod
in the vessel, be aware that in solids, material
cones can form which can change the switching point. We recommend selecting an installation location where the vibrating rod detects an
average value of the material cone. The mounting location of the vibrating rod must take the
location of the filling and emptying apertures of
the vessel into account. To compensate measurement errors caused by the material cone in
cylindrical tanks, the vibrating rod must be
mounted at a distance of d/6 from the vessel
wall. Here, a min. distance of approx. 40 cm
must be maintained (see fig. 2.4).
Moisture
Turn the cable entry of the instrument downwards (after installation) to avoid moisture ingress. For this purpose, the housing can be
rotated by approx. 330°. With vertically installed
instruments, loop the cable to the instrument
housing downwards so that rain or condensation water can drain off (see fig. 2.3).

3.1 Connection instructions VEGAVIB
Note
Switch off power supply before starting connection work.
The electrical connection must be carried out
according to the installed oscillator. Connect
supply voltage according to the wiring diagrams
on the following pages.
As a rule, connect VEGAVIB to vessel ground
(PA) or in plastic vessels, to nearest ground
potential. For this purpose, a thread (screw M4 x
5) is provided on the side on the hexagon of the
mounting boss. This connection serves to drain
off electrostatic charges.
In dust-Ex applications or applications acc. to
CENELEC, the PA terminal (on the hexagon of
the mounting boss) must be connected to the
potential equalisation line.

Set-up
4.1 VEGAVIB
Adjustment elements
The diode (2) can be checked with closed
housing. To adjust VEGAVIB, loosen the four
screws on the upper side of the housing with a
screwdriver and remove the housing cover.
The oscillators allow the following settings:
• A/B mode, only with oscillators C, R and T;
with oscillator Z: switch over via the signal
conditioning instrument
• sensitivity setting with potentiometer (not with
VEGAVIB 31)
With the A/B switch (4) you can change the
switching condition of the contactless electronic
switch (C), the relay output (R) or the transistor
output (T) . You can set the required mode acc.
to the "Function chart". A - max. level detection
or overfill protection, B - min. level detection or
dry run protection.
With oscillator Z the A/B mode can be switched
via the signal conditioning instrument. Note the
setup of the signal conditioning instrument.
With the potentiometer (5) you can change the
switching sensitivity and adapt it to the density
of the product. This is necessary for detection of
extremely light or heavy products. Turn the
potentiometer anticlockwise to make the vibrating probe more sensitive. Normally, a modification of the default setting will only be necessary
with extremely light products.
For most products, it is not necessary to change
the setting of the preset potentiometer (default
setting of the potentiometer = 5).
To modify the integration time, you have to use
oscillator Z in conjunction with a suitable signal
conditioning instrument (VEGATOR 534, 536,
537 and 636).
The instrument version for detection of solids in
water is adapted for use in water and cannot be
