1 Description of the measuring principle
Measuring principle
Short ultrasonic pulses in the range of 18 kHzto35 kHz are emittedby the transducer
to the product surface, reflected there and received by the transducer. The pulses
travel at the speed of sound - the elapsed time from emission to reception of the
signals depends on the level in the vessel.
The latest microcomputer technology and the proven processing software select the
level echofrom among any number offalse echoes andcalculate the exact distance to
the product surface. An integratedtemperature sensor detects the temperature in the
vessel and compensates the influence of temperature on the signal running time.
By simply entering the vessel dimensions, a level-proportional signal is generated
from the distance. It is not necessary to fill the vessel for adjustment.
Wide application range
OPTISOUND 3030 C, 3040 C and 3050 C ultrasonic sensors are especially suitable
for level measurement of solids, but are also good for liquids. The instrumentsdiffer in
the measuring range, the transducer version and the process fitting. Through diffe-
rent, adapted emitting frequencies and efficient transducers, levels in a measuring
range of 15 … 45 m (49.2 … 147.6 ft
transducers and process fittings also allow applications in corrosive products (depending on the model).
) can be measured. Resistant materials for the
A version suitable for each application
Adaptable sensors are a must for the wide variety of product characteristics and
installation conditions. OPTISOUND ultrasonic sensors meet this requirement with
versions suitable for all applications.
A practical mounting strap (option) enables flexible orientation of OPTISOUND 3030
C.
Four different versions of OPTISOUND 3040 C and 3050 C enable installation in
virtually all vessels and optimum orientation to the product cone:
l Version A compact in flange version
l Version B compact with swivelling holder
l Version C separate with swivelling holder
l Version D separate with thread fitting.
Unaffected by product properties
Fluctuations in product composition or even complete product changes do not influ-
ence the measuring result. A fresh adjustment is not necessary.
Service and maintenance friendly
Thanks to the non-contact measuringprinciple, OPTISOUND sensors are particularly
easy to service and maintain.

1.1 Application examples
Conveyor belt with sugar beets
Fig. 1: Profile measurement on a conveyor belt withOPTISOUND 3030
C
The sugarbeets used for sugar production arepoured from trucksonto conveyor belts
on which they are transported for further processing. OPTISOUND sensors are an
economic solution for profile monitoring. Ultrasonic waves are reflected by the medium, the integrated electronics detects the charging height of the conveyor belt. By
means of the mounting strap, OPTISOUND 3030 C can be optimally oriented to the
medium. Thanks to its high emitting power, fog, wind and moisture do not affect
measurement reliability.

Plastic granules
Fig. 2: Level measurement in a plastic granules silo with OPTISOUND
3040 C
Plastic granules are often stored in high, narrow silos that are filled pneumatically.
OPTISOUND ultrasonic sensors are particularly suitable for level measurement of
plastic granules. They are equipped with powerful transducers and optimised signal
processing. A swivelling holder on the mounting flange ensures optimum orientation
to the product, also when material cones form.

Measuring range
The reference plane for the measurement depends on the version. For the OPTISOUND 3040 C and 3050 C in flange version (version A) the lower edge of the flange
is the reference plane. For the versions with swivelling holder (versions B and C), with
threaded fitting (version D) as well as for OPTISOUND 3030 C, the lower edge of the
transducer is the reference plane. All statements concerning the measuring range as
well as the internal signal relate to this plane.
With all instruments, amin. distance from the lower edge of the flange - the so-called
dead zone, in which measurement is not possible - must be maintained. The exact
value of the dead zone, depending on the instrument version, is stated in the Technical data.

Gauge pressure in the vessel does not influence OPTISOUND. Low pressure or
vacuum, however damp the ultrasonic pulses. This influences the measuring result,
particularly if the level is very low. With pressures under -0,2 bar (-20 kPa) use a
different measuring principle, e.g. radar or guided radar (TDR).
Installation position
The mounting position of OPTISOUND 3030 C must be at least 200 mm (OPTISOUND 3040 C and 3050 C - at least 500 mm) from the vessel wall. If the sensor is
installed in the center of dished or spherical vessel tops, multiple echoes can result.
These can be faded out, however, through an appropriate adjustment.
If you cannot keep this distance, 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.

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.

The transducer should be mounted preferably without socket, flush with the vessel
top.
Ifthereflective properties of the medium are good, you can mount OPTISOUND on a
socket piece higherthan the transducerlength. The socket end should be smoothand
burr-free, if possible, also rounded. A false echo storage is recommended.
With liquids, align the sensor as close to vertical as possible to achieve optimum
measuring results.

Mounting information
The version with swivelling holder is recommended for optimum orientation to solids.
Vessel installations
Material heaps
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 wanted echo. Make sure
when planning your measuring location 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
Large material heaps are detected with several sensors, which can be mounted on e.
g. traverse cranes. For this type of application, it is best to direct the sensor perpendicularly to the solid surface.
Fig. 12: Transducers on traverse crane
Inflowing material
The instrumentsmust not bemounted in orabove the fillingstream. Make sure that the
product surface and not the inflowing material is detected.

Page 13
Mounting information
Fig. 13: Inflowing liquid
Foam
Air flow
Heat fluctuations
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 sensors with guided radar (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, you should mount OPTISOUND in a standpipe or use a different measuring principle, e.g. radar or guided radar (TDR).
Strong heat fluctuations, e.g. caused by the sun, can cause measurement errors. In
this case, you should use a sun shield.

Electrical connection
4 Electrical connection
4.1 General requirements
The power supply range can differ depending on the instrument version. The exact
range is stated in the Technical data.
Take note of country-specific installation standards (e.g. the VDE regulations in Ger-
many) as well as prevailing safety regulations and accident prevention rules.
In hazardous areas you should take note of the appropriate regulations, conformity
and type approval certificates of the sensors and power supply units.
4.2 Supply voltage
4 … 20 mA/HART two-wire
4 … 20 mA/HART four-wire
Power supply and current signal are carried over the same two-wire connection cable.
The requirements on the power supply are stated in the Technical dataof this Product
Information manual.
Power supply and current output are carried on two separate connection cables.
The standard version can be operated with an earth-connected current output, the
Exd version must be operated w ith a floating output.
The instrument is designed in protection class I. To maintain this protection class, it is
absolutely necessary that the ground conductor be connected to the internal ground
conductor terminal.
4.3 Connection cable
The sensors are connected with standard cable without screen. An outer cable diameter of 5 … 9 mm ensures the seal effect of the cable entry.
If strongelectromagnetic interference is expected, screened cable shouldbe used for
the signal lines.
In Ex applications, the corresponding installation regulations must be noted for the
connection cable.
4.4 Connection of the cable screen and grounding
If screened cable is required, the cable screen must be connected on both ends to
ground potential. If potential equalisation currents are expected, the connection on
the evaluation side must be made via a ceramic capacitor (e.g. 1 nF, 1500 V).
