Product description
30511-EN-050914

The transducer of the ultrasonic sensor emits short ultrasonic
pulses to the measured product.These pulses are reflected by
the product surface and received by the transducer as echoes.
The running time of the ultrasonic pulses from emission to
reception is proportional to the distance and hence to the level.
The determined level is converted into an appropriate output
signal and outputted as measured value.
Two-wire electronics 4…20 mA/HART for power supply and
measured value transmission on the same cable.
The power supply range can differ depending on the instru-
ment version.The exact range is stated in the "Technical data"
in the "Supplement".

4Mounting
4.1General instructions
Select an installation position you can easily reach for
mounting and connecting as well as later retrofitting of an
indicating and adjustment module.The housing can be rotated
by 330°without the use of any tools.You can also install the
indicating and adjustment module in four different positions
(each displaced by 90°).
Use the recommended cable (see chapter "Connecting to
power supply")and thighten the cable gland.
You can give your OPTISOUND 3030 Cadditional 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
The reference plane for the measuring range is the lower edge
of the transducer.
Make sure that a min.distance -the so called dead zone -
below the reference plane is maintained in which a measure-
ment is not possible.The exact value of the dead zone is
stated in the Technical data in the Supplement.

Gauge pressure in the vessel does not influence OPTISOUND
3030 C.Low pressure or vacuum,however,damp the
ultrasonic pulses.This influences the measuring result,

particularly if the level is very low.With pressures under -
0.2bar (-20 kPa)you should use a different measuring
principle,e.g.radar or guided radar (TDR).
4.2Mounting information
When mounting OPTISOUND 3030 C,keep a distance of at
least 200 mm (7.9in)to the vessel wall.If the sensor is
installed in the center of dished or rounded vessel tops,
multiple echoes can arise.These can,however,be faded out
by an appropriate adjustment (see chapter "Setup").
If this distance cannot be maintained,a false echo storage
should be carried out during setup.This applies particularly if
buildup on the vessel wall is expected.In this case,we
recommend repeating the false echo storage later on with
existing buildup.

2Vessel center or symmetry axis
In vessels with conical bottom it can be advantageous to
mount the sensor in the center of the vessel,as measurement
is then possible down to the lowest point of the vessel bottom.

If the reflective properties of the medium are good,you can
mount OPTISOUND 3030 Con a socket piece.You will find
recommended values of the socket heights in the following
illustration.The socket end should be smooth and burr-free,if
possible also rounded.Carry out a false echo storage.

In liquids,direct the sensor as perpendicular as possible to the
product surface to achieve optimum measurement results.
Fig.8:Orientation in liquids
To optimally align the sensor to solid products,a swivelling
holder (mounting strap)can be implemented.
Fig.9:Orientation in solids
To reduce the min.distance to the medium,you can also
mount OPTISOUND 3030 Cwith a beam deflector.By doing
this,it is possible to fill the vessel nearly to maximum.This
arrangement is particularly suitable for open vessels such as e.
g.overflow basins.

Fig.10:Beam deflector
The ultrasonic sensor should be installed at a location where
no installations cross the ultrasonic beam.
Vessel installations such as for example,ladders,limit
switches,heating spirals,struts etc.can cause false echoes
superimposed on the useful echo.Make sure when planning
your measuring site that the ultrasonic signals have "free
access"to the measured product.
If there are existing vessel installations,a false echo storage
should be carried out during setup.
If large vessel installations such as struts or supports cause
false echoes,these can be attenuated through supplementary
measures.Small,inclined sheet metal or plastic baffles above
the installations scatter the ultrasonic signals and avoid direct
false echoes.
Fig.11:Cover smooth profiles with deflectors
If there are agitators in the vessel,a false echo storage should
be carried out with the agitators in motion.This ensures that
the interfering reflections from the agitators are saved with the
blades in different positions.

Do not mount the instruments in or above the filling stream.
Make sure that you detect the product surface and not the
inflowing product.
Fig.13:Inflowing liquid
Through the action of filling,stirring and other processes in the
vessel,dense foams which considerably damp the emitted
signals may form on the product surface.
If foams are causing measurement errors,the sensor should
be used in a standpipe or,alternatively,the more suitable
guided radar sensors (TDR)should be used.

Guided radar is not influenced by foam generation and is
particularly suitable for such applications.
If there are strong air currents in the vessel,e.g.due to strong
winds in outdoor installations,or because of air turbulence,e.
g.through cyclone exhausting,you should mount OPTI-
SOUND 3030 Cin a standpipe or use a different measuring
principle,e.g.radar or guided radar (TDR).
By using a standpipe (surge or bypass tube), the influence of
vessel installations,foam generation and turbulence is
excluded.
Standpipes must extend all the way down to the requested
min.level,as measurement is only possible within the tube.

5Connecting to power supply
5.1Preparing the connection
Always observe the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltages are expected,overvoltage arresters should
be installed.
In hazardous areas you should take note of the appropriate
regulations,conformity and type approval certificates of the
sensors and power supply units.
Power supply and current signal are transmitted via the same
two-wire connection cable.The power supply range can differ
depending on the instrument version.The exact range is
stated in the "Technical data"in the Supplement.
Provide a reliable separation between the supply circuit and
the mains circuits acc.to DIN VDE 0106 part 101.
Bear in mind the following factors regarding supply voltage:
lthe reduction of the output voltage of the power supply unit
under nominal load (with a sensor current of 20.5mAor
22 mAin case of fault signal)
lthe influence of additional instruments in the circuit (see
load values in Technical data).
OPTISOUND 3030 Cis connected with standard two-wire
cable without screen.An outer cable diameter of 5... 9mm
ensures the seal effect of the cable entry.If electromagnetic
interference is expected,we recommend the use of screened
cable.
Connect the cable screen on both ends to ground potential.In
the sensor,the screen must be connected directly to the
internal ground terminal.The ground terminal outside on the
housing must be connected to the potential equalisation (low
impedance).
If potential equalisation currents are expected,the connection
on the evaluation side must be made via a ceramic capacitor
(e.g.1nF,1500 V). The low frequency potential equalisation
currents are thus suppressed,but the protective effect against
high frequency interference signals remains.

Take note of the corresponding installation regulations for Ex
applications.In particular,make sure that no potential equal-
isation currents flow over the cable screen.In case of
grounding on both sides this can be achieved by the use of a
capacitor or a separate potential equalisation.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2If an indicating and adjustment module is installed,remove
it by turning it slightly to the left.
3Loosen compression nut of the cable entry
4Remove approx.10 cm (4in)of the cable mantle,strip
approx.1cm (0.4in)insulation from the ends of the
individual wires
5Insert the cable into the sensor through the cable entry
6Lift the opening levers of the terminals with a screwdriver
(see following illustration)
7Insert the wire ends into the open terminals according to
the wiring plan
8Press down the opening levers of the terminals,you will
hear the terminal spring closing
9Check the hold of the wires in the terminals by lightly
pulling on them
10 Connect the screen to the internal ground terminal and the
external ground terminal to potential equalisation
11 Tighten the compression nut of the cable entry,the seal
ring must completely encircle the cable
12 Screw the housing cover back on
The electrical connection is finished.
