1 Product description
1.1 Function
Continuous level measurement with ultrasonic
sensors is based on the running time measurement of ultrasonic pulses.
VEGASON series 54 … 56 sensors are a
newly developed generation of extremely
compact ultrasonic sensors for level measurement. They were especially developed for
solids and larger measuring ranges. Preferred areas of application are silos, bunkers
or material heaps.
Due to the small housing dimensions and
process fittings, the compact sensors are a
very reasonable solution for your level measurement applications. With the integrated
display and a special sensor intelligence, in
conjunction with large measuring ranges,
they can be used for applications in which
the advantages of a non-contact measurement could never before be realized.
As output or measuring signal, the instruments produce a digital output signal which
is further processed in the VEGAMET signal
conditioning instrument or in the VEGALOG
processing system.
Measuring principle
Piezoceramic high performance transducers
emit focused ultrasonic pulses which are
reflected by the product surface. The measurement electronics prepares a precise picture of the environment out of the reflected
ultrasonic pulses. The transducers work both
as transmitter and receiver. As receiver, the
transducers are high-sensitivity piezo microphones.
Product description
Meas. distance
emission - reflection - reception
The measurement electronics precisely calculates the distance between transducer and
medium from the speed of sound and the
measured running time of the emitted sound
impulse. The distance is then converted into
a level proportional signal, and in conjunction
with the sensor parameter settings, made
available as precise, calibrated level value.
Since the speed of sound is subjected to a
temperature influence, the transducer also
continuously detects the ambient temperature, so that the level is precisely measured
even in case of varying ambient temperature.
4 VEGASON 54V … 56V
Product description
Output signal
The level-proportional measuring signal is
processed and outputted completely digitally. The digital processing of the measuring
signal ensures an accuracy which could be
never reached by an analogue measuring
signal, as the digital signal is always transmitted up to the last decimal point.
Varying line resistances or smallest leakage
currents do not influence the accuracy of the
digital technology. Even in case of failure, the
digital signal is always clear.
The parameter setting of the digital signal is
individual and represents the adjusted measuring range of the sensor.
Display of measured values
As an option, the series 50 ultrasonic sensors
can be equipped with an indicating instrument for direct, local level survey. The indicating instrument shows the precise level by
means of the analogue bar graph and the
digital number value. In addition to the indication in the sensor, you can have the level
displayed with the VEGADIS 50 external
indicating instrument at a distance of up to
25 m from the sensor. The external display of
measured values operates, like the integrated display, independently of the output
signal, can be modified through individual
parameter settings, and is powered by the
sensor.

1.3 Adjustment
Each measuring situation is unique. For that
reason, every ultrasonic sensor needs some
basic information on the application and the
environment, e.g. an empty vessel profile is
important for a reliable measurement. Beside
this, many other settings and adjustments
are possible on VEGASON ultrasonic sensors.
The adjustment and parameter setting of
ultrasonic sensors are carried out with
- the PC
- the detachable adjustment module
MINICOM
- the VEGAMET 514V or VEGAMET 515V
signal conditioning instrument
Adjustment with PC
The setup and adjustment of the ultrasonic
sensors is generally done on the PC with the
adjustment program VEGA Visual Operating
(VVO) under Windows®. The program leads
quickly through the adjustment and parameter setting by means of pictures, graphics
and process visualisations.

Adjustment with the PC to the digital signal and
supply cable between the sensors and the VEGAMET
signal conditioning instrument or on the sensor itself
The PC can be connected to any individual
position of the system or the signal cable. It is
connected by means of the two-wire PC
interface converter VEGACONNECT 2 to the
sensor, the signal cable or to the signal conditioning instrument or directly with a standard cable (RS 232) to the VEGALOG
processing system.
The adjustment and parameter data can be
saved with the adjustment software on the
PC and can be protected by passwords. On
request, the adjustments can be quickly
transferred to other sensors.

2.1 Type survey
VEGASON series 54 … 56 sensors are a
newly developed generation of extremely
compact ultrasonic sensors for large measuring ranges. VEGASON 51 … 53 are used for
shorter measuring ranges.
Due to the small housing dimensions and
process fittings, the compact sensors do
your level monitoring inconspicuously, and
above all, at reasonable cost. Swivelling
holders allow a quick alignment of the transducer to the product and solid surface.
Mounting is simplified by the option of separating the sensor electronics from the transducer. The sensor electronics can be
mounted at a distance of 300 m from the
transducer. It is then possible to mount the
transducer in environments with an ambient
temperature up to 150°C.
Common features
• Four versions (A … D).
• Application is solids and liquids.
• Measuring range 0.8 m … 70 m.

2.3 Approvals
When using ultrasonic sensors in Ex areas or
in marine applications, the instruments must
be suitable and approved for the explosion
zones and application areas.
The suitability is tested by approval authorities and is certified in approval documents.
VEGASON 50 ultrasonic sensors are approved for Ex zone 1, 10, 11, 21 and 22.
Please note the attached approval documents when using a sensor in Ex area.
2.4 Configuration of measuring systems
A measuring system consists of a sensor
and a processing unit. The processing unit (
the VEGAMET signal conditioning instrument
or the VEGALOG processing system) evaluates the level-proportional digital measuring
signals in a number of processing routines
and outputs the levels as individual current,
voltage or switching signals.
Two sensors can be connected via one twowire cable to the VEGAMET 515V signal
conditioning instrument. Up to 255 sensors
can be connected to the VEGALOG 571
processing system. 15 sensors (loop powered) on one two-wire cable.
Beside the output of the levels in percent,
cubicmeters or other physical units, also
current, voltage or switching signal (relay or
transistor), the levels can be also processed
by linked processing algorithms. Scaling,
linearisation, calculation of linearisation
curves, differential generation, addition or
tendency processing are fixed implemented
as processing routines in the VEGALOG
processing systems and VEGAMET and are
easily accessible via the menu.
On the following pages you find examples of
two different instrument configurations
(measuring systems) consisting of sensor(s)
and processing system.

4 Mounting and installation
4.1 Mounting
Mounting and installation
Version A
Sensors in version A (flange version) are
supplied completely mounted and ready for
operation. Immediately after mounting on the
vessel and electrical connection, they are
ready for operation.
Version B
The sensors in version B are supplied in two
parts (transducer and sensor electronics).
First of all, mount the transducer on the vessel or above the medium. There is a four-pole
jack at the end of the transducer tube. The
respective counterpart to the jack protrudes
out of the lower side of the sensor electronics
housing. Insert the plug of the sensor electronics (only possible in one position), into the
jack of the transducer tube. Continue pushing the electronics housing onto the transducer tube, on which there is a wide and a
narrow groove.

headless screw
Mounting groove (must
no longer be visible after
mounting)
The wide groove is used for locking the
headless screws. The narrow groove is a
marking for mounting. Move the electronics
housing farther down over the transducer
tube until the mounting groove is no longer
visible. Fasten the housing with the headless
screws to the transducer tube. Use a 5 mm
hexagon screwdriver (or Allen wrench).

Mounting and installation
Version C and D
The sensors in version C and D are supplied
in three parts (transducer, sensor electronics
and transducer cable). First mount the transducer (see version B). There is a four-pole
jack at the transducer tube end. A respective
counterpart to the jack is provided in the
connection cylinder of the transducer cable.
Insert the connection cylinder plug into the
jack of the transducer tube.

On the end of the transducer tube you find a
wide and a narrow groove. The wide groove
is used for locking the cylinder with the headless screws. The narrow groove is the
mounting mark.
Then push the connection cylinder onto the
transducer tube (with a slight swivelling motion) until the mounting mark is no longer
visible.
When the mounting mark is covered by the
cylinder, fasten the cylinder with the two
headless screws. Use a 5 mm hexagon
screwdriver (or Allen wrench).
Now mount the sensor electronics in the
requested location. The sensor electronics is
fastened to a mounting bracket, so that it can
be mounted to a plane surface or to the wall.
Make sure that the sensor housing is
mounted in such a way that there is enough
space above the housing to open the cover.
Now insert the plug at the other end of the
transducer cable into the jack on the electronics housing.
Note:
Avoid bending the transducer cable too
sharply when laying it out. This is special
cable which could otherwise be damaged.
In addition, make sure that the cable is not
damaged during operation. A signal with a
voltage of approx. 1 kV is transmitted (which
could be a danger in Ex areas if the cable is
damaged) is transmitted via the screened
cable cones.

Beam angle and false echoes
At greater distances, the energy of the ultra-
sonic impulses distributes over a large area,
The ultrasonic impulses are focused by the
transducer. The impulses leave the transducer in conical form similar to the beam
pattern of a spotlight. The beam angle is 4°
thus causing weaker echoes from obstruct-
ing surfaces. The interfering signals are
therefore less critical than those at close
range.

Any object, e.g. tubes or struts inside this
emission cone will cause a false echo. Especially within the first few meters of the emis-

sion cone, pipes, struts, or other installations
can interfere with the measurement. At a
distance of 6 m, the false echo of a strut has
an amplitude nine times greater than at a
distance of 18 m.
