3.2Principle of operation
VEGAMIP 61 is a microwave barrier for level detection.
It is designed for industrial use in all areas of process technology and
can be used in bulk solids and liquids.
Typical applications are overfill and dry run protection.With an
operating distance of 100 m,VEGAMIP 61 can be used,for example,
in bulk solids silos with large diameters.Thanks to its simple and
rugged measuring system,VEGAMIP 61 is virtually unaffected by the
process and the chemical and physical properties of the medium.

VEGAMIP 61 can also be used for detection of vehicles and ships or
for material recognition on conveyor belts.
It works even under extremely difficult conditions:different grain sizes,
contamination,extreme filling noise,high temperatures,strong dust
generation and abrasive products are all no problem for the
instrument.
The VEGAMIP 61 consists of the following components.

5Encapsulated horn antenna with PTFE cover
The emitting unit transmits a focused microwave signal via horn
antenna to the receiving unit on the opposite side.If there is medium
between emitting and receiving unit,the signal is damped.This
change is detected by the built-in electronics module and converted
into a switching command.
3.3Packaging,transport and storage
Your instrument was protected by packaging during transport.Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.
The packaging of standard instruments consists of environment-
friendly,recyclable cardboard.For special versions,PE foam or PE foil
is also used.Dispose of the packaging material via specialised
recycling companies.
Transport must be carried out under consideration of the notes on the
transport packaging.Nonobservance of these instructions can cause
damage to the device.
The delivery must be checked for completeness and possible transit
damage immediately at receipt.Ascertained transit damage or
concealed defects must be appropriately dealt with.

With high process temperatures exceeding 80 °C,you have to use a
mounting adapter for the emitting and the receiving unit.The mounting
adapter can only be used with the threaded version (internal horn
antenna with PTFE cover).

4Mounting
4.1General instructions
With instruments with threaded process fitting,suitable tools must be
applied for tightening the hexagon.
Warning:
The housing must not be used to screw the instrument in!Applying
tightening force can damage internal parts of the housing.
Make sure that all parts of the instrument exposed to the process,in
particular the active measuring component,process seal and process
fitting,are suitable for the existing process conditions.These include
above all the process pressure,process temperature as well as the
chemical properties of the medium.
You can find the specifications in chapter "Technical data"and on the
type label.
Use the recommended cables (see chapter "Connecting to power
supply")and tighten the cable gland.
You can give your instrument additional 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 outdoor mounting as well as installation in areas
where high humidity is expected (e.g.through cleaning processes)or
on cooled or heated vessels.
4.2Instructions for installation
If possible,install VEGAMIP 61 in a position where strong signal
damping by the medium is expected.
Avoid mounting the instrument too close to the vessel wall.Reflections
from the vessel wall or from vessel installation can influence the
switching accuracy.

The VEGAMIP 61 requires a minimum product strength to detect
different products.
Dependent on the medium there will be a respective product
thickness.
The properties of the medium are also dependent on the granulation
size,the bulk density and the moisture content.
Some exemplary reference values for the min.strength of the medium:
Product type Medium Min.product
strength
Plastic granules PTFE,PS >1000 mm
PP,PE,HDPE,POM >500 mm
PA,PVC,PVDF >250 mm
Foodstuffs and wood Flour >100 mm
Cereals,corn,rice >100 mm
Wood chips (dry)>500 mm
Wood chips (moist)>100 mm
Mineral products /Ore Stones (e.g.limestone)>100 mm
Cement,clinker >100 mm
Glass (crushed)>100 mm
Coal >50 mm
Bauxite >100 mm
Ore >100 mm
IfVEGAMIP 61 is mounted in the filling stream,unwanted false
measurement signals can be generated.For this reason,mount
VEGAMIP 61 at a position in the vessel where no disturbances,e.g.
from filling openings,agitators,etc., can occur.
Microwaves can penetrate non-conductive materials.Hence,it is
possible to measure through the wall of non-conductive vessels.

In general,the same as for metal vessels applies to concrete vessels
due to the steel braining.
In general,the same as for metal vessels applies to wood vessels due
to the liquid absorption of the wood.
VEGAMIP 61 can be used for detection of products in pipelines.In
pipelines of non-metallic products such as plastic or glass,the
measured product can be detected through the pipe wall.

Note:
In the case of VEGAMIP 61 with NPT thread,the instrument seals in
the thread itself.Hence,no counter nut is necessary for these
versions.
Avoid long sockets in which the medium can remain and if possible,
mount VEGAMIP 61 front-flush.This applies mainly if buildup and dust
are expected.

If a front-flush installation is not possible,you can fill long sockets with
a plastic or ceramic cylinder to avoid build up of bulk solids and dust
deposits.Select the material according to the diameter of the socket
and adapt the length as far as possible to the shape of the vessel wall.
Secure the filling material against falling out or turning.If using a fixing
screw is technically not possible,you can secure the material in the
socket with an adhesive.

In very abrasive products,VEGAMIP 61 should be installed with a
mounting adapter or in front of a suitable window.In this case,you
have to use a window material which is appropriately resistant.
In case of strong vessel vibrations,the VEGAMIP 61 should be
mounted with anti vibration blocks or rubber buffers.

Angle
For an optimum switching signal,the two sensors must be adapted to
each other.The accuracy must be in a range of ±5°.
Offset
The two sensors can have an offset of up to <5%of the sensor
distance (d)to each other.Example:with a sensor distance of
1000 mm,the two sensors must have an offset of max.50 mm to each
other.
General rule:the bigger the antenna and the better it focusses,the
more precise the orientation has to be.
