Product description
1 Product description
VEGASWING 61 and 63
VEGASWING 61/63 vibrating level switches
are used for level detection of liquids.
Typical applications are overfill and dry run
protection. Using a tuning fork with a length
of only 40 mm, VEGASWING 61 opens up
new areas of application, e.g. in pipelines
from DN 25. Power supply and output signal
correspond to the Namur interface acc. to
IEC 60947-5-6 (EN 50227).
VEGASWING series 60 vibrating level
switches detect levels of liquids with a vis-
cosity of 0.1 … 10.000 mPa s and a density
of ≥0.5 g/cm3. Modular construction enables
their use in vessels, tanks and pipelines.
Thanks to its simple and rugged measuring
system, VEGASWING is virtually unaffected
by the chemical and physical properties of
the liquid. It does its job even under unfa-
vourable conditions such as turbulences, air
bubbles, foam generation, buildup, strong
external vibration or constantly changing
products.
• Tuning fork with only 40 mm length.
• Thread from ¾ and flanges from DN 25
(ANSI 1").
• Process temperature -50°C ... +250°C
without shock limitation.

Function and application
2 Function and application
2.1 Principle of operation
VEGASWING vibrating level switches detect
levels in almost all liquids.
Viscosity: 0.1 ... 10.000 mPa s
Density: 0.5 ... 2.5 g/cm3
VEGASWING measuring principle
The tuning fork is piezoelectrically energised
and vibrates at its mechanical resonance
frequency of approx. 1200 Hz. The piezo-
electric elements are fastened mechanically
and are therefore not subject to temperature
shock limitations. When the tuning fork is
submerged in the product, the frequency
changes. This change is detected by the
integrated oscillator and converted into a
switching command.
The integrated fault monitoring detects:
- interruption of the connection cable to the
piezoelectric elements
- extreme wear on the tuning fork
- break of the tuning fork
- absence of vibration.
In case of failure, a defined current
(≤1.0 mA) is impressed on the cable to the
NAMUR amplifier.
Compact instrument with NAMUR
output
The oscillator delivers as output signal a
current jump acc. to IEC 60947-5-6. The
switching signal is further processed via
complementary NAMUR processing sys-
tems, e.g. PLC input card or remote I/O.
2.2 Measuring system

Mounting
4 Mounting
4.1 VEGASWING
In principle, VEGASWING can be mounted in
any position. The instrument must be
mounted such that the tuning fork is at the
height of the required switching point. Note
the following installation instructions.
Transport
Do not hold VEGASWING on the tuning fork.
Especially with flange and tube versions, the
tuning fork can be damaged simply by the
weight of the instrument. Transport enamelled
and ECTFE coated instruments very carefully
and avoid touching the tuning fork.
Switching point
The tuning fork is provided with lateral mark-
ings (notches), marking the switching point
with vertical installation. The switching point
refers to the medium water at the basic set-
ting of the density switch ≥0.7 g/cm3. Make
sure when mounting VEGASWING that this
marking is at the height of the requested
level. Note that the switching point of the
instrument shifts when the medium has a
density other than that of water (water =
1.0 g/cm3). For products < 0.7 g/cm3the
density switch has to be set to ≥0.5 g/cm3.
Direct exchange of a VEGASWING 81A
or 71A (with thread G1A)
If VEGASWING 61 with a sensor length the
same as VEGASWING 81A or 71A is
mounted into an existing mounting boss G1A,
it is ensured that VEGASWING 61 will seal
correctly.

Mounting
Fig. 2.3
Adhesive products
In case of horizontal mounting in adhesive
and viscous products, the surfaces of the
tuning fork should be vertical in order to
reduce buildup on the tuning fork (see fig.
2.2). The orientation of the tuning fork is
marked by a notch on the hexagon of VEGA-
SWING. With this you can check the orienta-
tion of the tuning fork when screwing it in.
When the hexagon touches the seal, the
thread can still be turned by approx. half a
turn. This is sufficient to reach the recom-
mended installation position.
In case of adhesive and viscous products,
the tuning fork should protrude into the ves-
sel to avoid buildup. Sockets for flanges and
mounting bosses should therefore not ex-
ceed a certain length. The tuning fork should
protrude into the vessel/pipeline.
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 similar
material or use a sufficiently resistant seal
ring.
Vibrations
Extreme vibrations and shocks, e.g. caused
by stirrers and turbulence in the vessel, can
cause the extension tube of VEGASWING
63 to vibrate. This will cause increased stress
on the upper weld joint.
To counteract this, provide a support or
straining directly above the tuning fork to
firmly hold the extension tube (see fig. 2.3).
This applies mainly to applications in
Ex areas category 1G or WHG. Make
sure that the tube is not subjected to
bending forces.
Stirrers
Through the action of stirrers or similar de-
vices, the level switches can be subjected to
strong lateral forces. For this reason, do not
use an overlong extension tube for VEGA-
SWING 63, but check if it is possible to
mount a VEGASWING 61 level switch on the
side of the vessel in horizontal position.
Cable entries
Use a cable with round wire cross-section
and tighten the cable entry firmly. The cable
entry is suitable fro cable diameters from
5 mm to 9 mm.

25470-EN-030707
Mounting
Fig. 2.5
Fig. 2.4
Moisture
Turn the cable entries of horizontally mounted
instruments downwards to avoid moisture in-
gress. For this purpose the plastic housing
can be rotated by approx. 330°. For vertically
installed instruments, loop the cable con-
nected to the instrument housing downwards
so that rain and condensation water can
drain off. This applies mainly when mounting
outdoors, in humid areas (e.g. by cleaning
processes) or on cooled or heated vessels
(see fig. 2.4).
Lateral load
Make sure that the vibrating element is not
subjected to lateral forces. To assure this,
mount the instrument at a location in the ves-
sel where no adverse conditions, e.g.
caused by stirrers, filling openings etc. can
occur. This applies mainly to instrument types
with extension tube (see fig. 2.5). The sur-
faces of the tuning fork should be parallel to
the product movement.
Chemical resistance
When applied in Ex areas zone 0,
VEGASWING must be used only in
combustible liquids against which the
materials of the tuning fork system are suffi-
ciently chemically resistant.
VEGASWING with enamel
Treat instruments with enamel coating very
carefully and avoid shocks. Unpack
VEGASWING directly before installation.
Insert VEGASWING carefully into the vessel
opening and avoid touching any sharp ves-
sel parts.
Flow
(e.g. in tubes)
When mounting in pipelines or in vessels
having a certain flow direction, VEGASWING
should be installed such that the surfaces of
the tuning fork are aligned with that direction.

Marking
Mounting
Mounting boss
VEGASWING’s thread starting point is de-
fined. This means that every VEGASWING is
in the same position after being screwed in.
Remove therefore the supplied seal from the
thread of VEGASWING. This seal is not re-
quired when using a welded socket. Screw
VEGASWING into the welded socket.
You can determine the subsequent position
of VEGASWING before welding (see fig. 2.2).
Mark the appropriate position of the welded
socket. Before welding, unscrew VEGA-
SWING and remove the rubber ring from the
socket.
The welded socket has a marking (notch).
Weld the socket with the notch facing up-
wards, or in the case of pipelines, aligned
with the direction of flow (see fig. 2.6).

5 Electrical connection
5.1 VEGASWING 61 and 63
Note
Switch off the power supply before starting
connection work.
Connect supply voltage according to the
following wiring diagrams.
As a rule, connect VEGASWING to vessel
ground (PA) or, in plastic vessels, to the
nearest ground potential. For this purpose, a
grounding terminal is provided between the
cable entries on the side of the housing. This
connection serves to drain off electrostatic
charges.
In Ex applications, it is also necessary to note
the installation regulations for hazardous
areas.

6.1 VEGASWING 61 and 63
The numbers in brackets relate to the follow-
ing illustration.
Display and adjustment elements
The switching status of the electronics can be
checked when the housing is closed (LED
display).
In basic adjustment, products with a density
> 0.7 g/cm3can be detected. For products
with lower density, the switch must be set to
> 0.5 g/cm3.
The following display and adjustment ele-
ments are located on the oscillator:
- LED display (1)
- DIL switch for adaptation of the switching
point (3) and characteristics reversal (2)
- test key (4)
Note:
When testing, always immerse the tuning fork
of VEGASWING into a liquid. Do not test the
functionality of VEGASWING by touching it.
This can damage the sensor.
Characteristics reversal (2)
Characteristics reversal is possible with the
DIL switch. You can choose between falling
characteristics (switch position max.) and
rising characteristics (switch position min.).
The requested current can thus be
outputted.
min. rising characteristics (High current
when immersed)
max. falling characteristics (Low current
when immersed)
NAMUR output switchable to falling or rising
characteristics (see also „6.2 Function chart).
In applications acc. to WHG, the DIL switch
must be set to position max.
Switching point adaptation (3)
With this DIL switch (3) you can set the
switching point for liquids with a density
between 0.5 and 0.7 g/cm³. In the basic
setting, liquids with a density > 0.7 g/cm³ can
be detected. For products with lower density,
you have to set the switch to > 0.5 g/cm³.
The information on the position of the switch
point relates to water as the medium (density
value 1.0 g/cm³). In products with a different
density the switching point shifts, depending
on density and type of installation, either in
the direction of the housing or the tuning fork
end. See also 4 Mounting - Switching point.
Fault monitoring
The oscillator of VEGASWING monitors the
instrument continuously. The following criteria
will be checked:
- corrosion or damage to the tuning fork
- failure of the tuning fork
- line break to the actuation.
