Radar –Level measurement of bulk solids 3
31488-EN-070320

1Description of the measuring principle
Measuring principle
Extremely short microwave pulses with low emitted power are
transmitted by the antenna system to the measured product,re-
flected by the product surface and received back by the antenna
system.Radar waves travel at the speed of light.The time from
emission to reception of the signals is proportional to the level in
the vessel.Aspecial time stretching procedure ensures reliable
and precise measurement of the extremely short transmission
periods.
The latest microprocessor technology and the proven software
ECHOFOX select the level echo from among a large number of
false echoes and measure it precisely.
By simply entering the vessel dimensions,a level-proportional
signal is generated out of the distance.Filling the vessel is not
necessary for the adjustment.
Wide application range
VEGAPULS 67 and 68 radar sensors are particularly suitable for
level measurement of bulk solids.The mechanical construction
as well as the electronics were optimized for this application.
Through the special horn and parabolic antennas and the im-
proved dynamic range of the receiver,levels in measuring ranges
up to 70 m(230 ft)can be measured.Areliable measurement is
possible with dielectric values from 1.6.
Versions for real-world applications
Adaptable sensors are required for the widely varying product
characteristics and mounting situations.That is why VEGAPULS
67 and 68 radar sensors are available with flange fittings,mount-
ing strap as well as swivelling holder.An integrated connectionfor
air rinsing is also available with VEGAPULS 68.An optional tem-
perature adapter extends the application range to product tem-
peratures up to 200 °C(392 °F). Mounting is very easy and re-
quires no additional work on the measurement loop.
Independent of product characteristics
Fluctuations in product composition or even complete product
changes do not influence the measuring result.Afresh adjust-
ment is not necessary.
Device selection
VEGAPULS 67 and 68 radar sensors are available with different
horn and parabolic antennas.This yields a variety of instrument-
specific beam angles and measurement characteristics.Selec-
tion of a suitable antenna depends on the respective application.
For detailed selection you can use the tools "Finder"and "Con-
figurator"on our website or contact our respective agency.
1.1Application examples
Plastic granules
Fig.1:Level measurement in a plastic granules silo with VEGAPULS 67
Plastic granules and powder are often stored in high,narrow silos
which are filled pneumatically.Typical conditions are filling noise,
material cones and poor reflective properties.
The high sensitivity of the VEGAPULS 67 sensor provides suffi-
cient power reserves for a reliable level measurement even with
widely varying product surface geometries.
Clinker silo
Fig.2:Level measurement in a clinker silo with VEGAPULS 68
Clinker is an additive for concrete and is stored in large silos or
bunkers.Its abrasive properties as well as extreme dust gener-
ation during filling place heavy demands on the level measure-
ment.
The VEGAPULS 68 sensor is the optimum solution for level
measurement.Its parabolic antenna powerfully focuses the mi-
crowaves,generating a strong useful signal.Interference from
struts or installations is excluded.

Installation position
Mount the sensor 200 mm (7.874 in)away from the vessel wall.
To measure as much of the vessel volumeas possible,the sensor
should be aligned so that the measuring beam reaches the lowest
level in the vessel.In a cylindrical silo with conical outlet,the
easiest way is to mount the instrument in the center of the silo.

Mounting and orientation of VEGAPULS 68
Fig.7:Orientation of VEGAPULS 68 when mounting in the silo center
If mounting in the center of the silo is not possible,the sensor can
be directed to the vessel center by means of an optional swivel-
ling holder.The description in the operating instructions manual
of the sensors gives a simple overview of how to determine the
inclination angle.

center.
Socket VEGAPULS 67
For mounting VEGAPULS 67 on a socket,a respective compres-
sion flange for DN 80 (ASME 3"or JIS 80)as well as a suitable
adapter flange are available.
To keep false reflections from a vessel socket to a minimum,the
socket should be as short as possible.The socket end should be
rounded.
Fig.9:Recommended socket mounting
If the medium has good reflective properties,VEGAPULS 67 can
also be mounted on a longer socket piece.Recommended val-
ues for socket heights are specified in the operating instructions
manual.You must carry out a false echo storage afterwards.
Tip:
In new plants,it is useful to incline the vessel socket in
the direction of emptying.False reflections from the ves-
sel wall are thus reduced and measurement all the way
down to the conical outlet is possible.
Fig.10:Orientation in silos
Socket VEGAPULS 68
The socket piece should be dimensioned in such a way that the
antenna end protrudes slightly out of the socket.

ca. 10 mm
Fig.11:Recommended socket mounting
When using a swivelling holder,keep in mind that the distance
between antenna and socket gets smaller as the inclination of the
sensor increases.Additional false reflections may be generated
which can influence the measuring result at close range.
If the medium has good reflective properties,VEGAPULS 68 can
also be mounted on a longer socket piece.Recommended val-
ues for socket heights are specified in the operating instructions
manual of the sensor.
Mounting in a multiple chamber silo
The silo walls of multiple chamber silos are often made of profile
walls,such as e.g.profile sheeting,to ensure the required stabil-
ity.If the radar sensor is mounted very close to a heavily struc-
tured vessel wall,considerable false reflections can be gener-
ated.Hence the sensor should be mounted at a large distance
from the separating wall.The optimal mounting position is the
outer wall of the silo with the sensor directed towards the empty-
ing aperture in the silo center.
Fig.12:Installation in multiple chamber silos
Fig.13:Orientation in multiple chamber silos
Vessel installations
Silo installations such as e.g.ladders,level switches,struts,and
also structured vessel walls,can cause false echoes that get
superimposed on the useful echo.The mounting location of the
radar sensor should be a place where no installations cross the
microwave signals.Make sure when planning your measurement
loop that the radar signals have a "clear view"to the product.
Material heaps
Large material heaps are best measured with several instru-
ments,which can be mounted on e.g.traverse cranes.For this
type of application it is advantageous to orient the sensor perpen-
dicular to the bulk solid surface.
The sensors cannot influence each other.

4Electrical connection
4.1General prerequisites
The supply voltage range can differ depending on the instrument
version.You can find exact specifications in chapter "Technical
data".
Take note of country-specific installation standards (e.g.the VDE
regulations in Germany)as well as prevailing safety regulations
and accident prevention rules.
In hazardous areas you should take note of the appro-
priate regulations,conformity and type approval certifi-
cates of the sensors and power supply units.
4.2Voltage supply
4…20 mA/HART two-wire
The VEGA power supply units VEGATRENN 149AEx,VEGAS-
TAB 690,VEGADIS 371 as well as VEGAMET signal condition-
ing instruments are suitable for power supply.When one of these
instruments is used,a reliable separation of the supply circuits
from the mains circuits according to DIN VDE 0106 part 101 is
ensured for the sensor.
4…20 mA/HART four-wire
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 with a floating
output.
The instrument is designed in protection class I.To maintain this
protection class,it is absolutely necessary that the ground con-
ductor be connected to the internal ground conductor terminal.
Profibus PA
Power is supplied by a Profibus DP/PA segment coupler or a
VEGALOG 571 EP input card.
Fig.15:Integration of instruments in a Profibus PA system via segment coupler DP/
PA or data recording systems with Profibus PA input card
Foundation Fieldbus
Power supply via the H1Fieldbus cable.
4.3Connection cable
General
The sensors are connected with standard cable without screen.
An outer cable diameter of 5…9mm ensures the seal effect of the
cable entry.
4…20 mA/HART two-wire and four-wire
If electromagnetic interference is expected which is above the
test values of EN 61326 for industrial areas,screened cable
should be used.InHART multidrop mode the use of screened
cable is generally recommended.
Profibus PA,Foundation Fieldbus
The installation must be carried out according to the appropriate
bus specification.The sensor is connected respectively with
screened cable according to the bus specification.Make sure
that the bus is terminated via appropriate terminating resistors.
For power supply,an approved installation cable with PE con-
ductor is also required.
InEx applications,the corresponding installation regu-
lations must be noted for the connection cable.
4.4Connection of the cable screen and
grounding
If screened cable is necessary,the cable screen must be con-
nected 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.1nF,1500 V).
Profibus PA,Foundation Fieldbus
In systems with potential separation,the cable screen is con-
nected directly to ground potential on the power supply unit,in
the connection box and directly on the sensor.
In systems without potential equalisation,connect the cable
screen directly to ground potential only at the power supply unit
and at the sensor -do not connect to ground potential in the
connection box or T-distributor.
