3.2 Principle of operation
VEGASWING 61 is a point level sensor with tuning fork for level
detection.
It is designed for industrial use in all areas of process technology and
can be used in liquids.
Typicalapplicationsareoverllanddryrunprotection.Withitstuning
fork of only 40 mm length, VEGASWING 61 can also be mounted e.g.
in pipelines from DN 32.The small tuning fork allows use in vessels,
tanks and pipes. Thanks to its simple and robust measuring system,
VEGASWING61isvirtuallyunaectedbythechemicalandphysical
properties of the liquid.
Itfunctionsevenunderdicultconditionssuchasturbulence,airbub-
bles, foam generation, buildup, strong external vibration or changing
products.
Fault monitoring
The electronics module of VEGASWING 61 continuously monitors via
frequency evaluation the following criteria:
• Strong corrosion or damage on the tuning fork
• Loss of vibration
• Linebreaktothepiezodrive
If a malfunction is detected or in case of power failure, the electronics
takesonadenedswitchingcondition,i.e.thecontactlesselectronic
switchopens(safecondition).
Thetuningforkispiezoelectricallyenergisedandvibratesatits
mechanicalresonancefrequencyofapprox.1200Hz.Thepiezosare
xedmechanicallyandarehencenotsubjecttotemperatureshock
limitations.The frequency changes when the tuning fork is covered
by the medium.This change is detected by the integrated electronics
module and converted into a switching command.
VEGASWING 61 is a compact instrument, i.e. it can be operated with-
out 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pumpetc.).
Thedataforpowersupplyarespeciedinchapter"Technical data".
3.3 Operation
The switching condition of VEGASWING 61 with plastic housing can
becheckedwhenthehousingisclosed(signallamp).Withthebasic
setting,productswithadensity>0.7g/cm³(0.025lbs/in³)canbede-
tected.The instrument can be adapted if products with lower density
are to be measured.
Ontheelectronicsmoduleyouwillndthefollowingindicatingand
adjustment elements:
• Signallampforindicationoftheswitchingcondition(green/red)
• DIL switch for sensitivity adjustment

4.1 General instructions
Make sure that all parts of the instrument coming in direct contact with
the process, especially the sensor element, process seal and process
ttingandsuspensioncable,aresuitablefortheexistingprocess
conditions, such as process pressure, process temperature as well as
the chemical properties of the medium.
Youcanndthespecicationsinchapter"Technical data"andonthe
type plate.
In general, VEGASWING 61 can be installed in any position.The
instrument only has to be mounted in such a way that the tuning fork
is at the height of the desired switching point.
Thetuningforkhaslateralmarkings(notches)thatindicatethe
switching point with vertical mounting.The switching point refers
towaterwiththebasicsettingofthesensitivityswitch≥0.7g/cm³
(0.025lbs/in³).WhenmountingVEGASWING61,makesurethat
this marking is at the height of the requested switching point. Keep in
mind that the switching point of the instrument is shifted if the medium
hasadensityotherthanwater-water1g/cm³(0.036lbs/in³).For
products<0.7g/cm³(0.025lbs/in³)and>0.5g/cm³(0.018lbs/in³)
thedensityswitchmustbesetto≥0.5g/cm³.
Keepinmindthatfoamswithadensity>0.45g/cm³(0.016lbs/in³)
are detected by the sensor. This can cause faulty switchings particu-
lary when used as dry run protection system.

Caution:
Do not hold VEGASWING 61 on the tuning fork. Particularly with
angeortubeversions,thetuningforkcanbedamagedjustbythe
weight of the instrument.Transport coated instruments very carefully
and avoid touching the tuning fork.
Remove the packaging or the protective cover just before installation.
Theprocesstting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speciedinchapter"Technical
data"oronthetypelabelofthesensor.
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 screwing in.
4.2 Instructions for installation
VEGASWING61hasadenedthreadstartingpoint.Thismeans
that every VEGASWING 61 is in the same fork position after being
screwed in. Remove therefore the supplied seal from the thread of
VEGASWING 61.This seal is not required when using a welded
socket with O-ring in front.
Keep in mind that this welded socket is not suitable for coated instru-
ment versions.
Screw VEGASWING 61 completely into the welded socket.The
later position can be determined already before welding. Mark the
appropriate position of the welded socket. Before welding, unscrew
VEGASWING 61 and remove the rubber ring from the welded socket.
Theweldedsockethasamarking(notch).Weldthesocketwiththe
notchfacingupward,orincaseofpipelines(DN32uptoDN50),
alignedwiththedirectionofow.

1 Marking
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.Onthescrewedversionyouwillnd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stillbeturnedbyapprox.halfaturn.Thisissucientto
reach the recommended installation position.
Withangeversions,theforkisdirectedtotheangeholes.
When used in adhesive and viscous products, the tuning fork should
protrude into the vessel to avoid buildup. For that reason, sockets
forangesandmountingbossesshouldbeavoidedwhenmounting
horizontally.
IfVEGASWING61ismountedinthellingstream,unwantedfalse
measurement signals can be generated. For this reason, mount VE-
GASWING 61 at a position in the vessel where no disturbances, e.g.
fromllingopenings,agitators,etc.,canoccur.
Tominimiseowresistancecausedbythetuningfork,VEGASWING
61 should be mounted in such a way that the surfaces of the blades
are parallel to the product movement.
The gas-tight leadthrough avoids due to a second sealing the
uncontrolled penetration of the medium.The lifetime of the gastight
leadthrough depends ont he chemical resistance of the materials.
See"Technical data".
Caution:
Ifitisdetermined(e.g.byanerrormessageofVEGASWING61)that
medium has already penetrated into the vibrating element, the instru-
ment must be exchanged immediately.

WiththisDILswitch(3)youcansettheswitchingpointtoliquids
havingadensitybetween0.5and0.7g/cm³(0.018and0.025lbs/
in³).Withthebasicsetting,liquidswithadensityof>0.7g/cm³(0.025
lbs/in³)canbedetected.Inliquidswithlowerdensity,youmustset
theswitchto>0.5g/cm³(0.018lbs/in³).Thespecicationsforthe
position of the switching point relate to water - density value 1 g/cm³
(0.036lbs/in³).Inproductswithadierentdensity,theswitchingpoint
will shift in the direction of the housing or tuning fork end depending
on the density and type of installation.
Note:
Keepinmindthatfoamswithadensity>0.45g/cm³(0.016lbs/in³)
are detected by the sensor. This can cause faulty switchings particu-
lary when used as dry run protection system.
