2 For your safety
The emitting frequencies of the sensors depend on the model, but are
all in the K band range. The low transmitting power lies far below the
internationally permitted limit value. When the instrument is used
correctly, it presents no danger to human health. It may be operated
without restriction outside of closed vessels.
2.5 CE conformity
The device fulfills the legal requirements of the applicable EC
guidelines. By affixing the CE marking, VEGA confirms successful
testing of the product.
Only with class A instruments:
The device is a class A instrument designed for use in an industrial
environment. When used in a different environment, e.g., in a living
area, the electromagnetic compatibility must be ensured by the user. If
necessary, suitable screening measures against conducted and
emitted disturbances must be taken.
You can find the conformity certificate in the download section under
www.vega.com.
2.6 Radio license for Europe
The instrument is approved according to EN 300440-1 V1.5.1 (2009-
03) and EN 300440-2 V1.531 (2009-03) and can be used without radio
limitations.

3.2 Principle of operation
Application area
41912-EN-120228
VEGAMIP R62 • - Relay 7
VEGAMIP 62 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.

3 Product description
Typical applications are overfill and dry run protection. With an
operating distance of 100 m, VEGAMIP 62 can be used, for example,
in bulk solids silos with large diameters. Thanks to its simple and
rugged measuring system, VEGAMIP 62 is virtually unaffected by the
process and the chemical and physical properties of the medium.
VEGAMIP 62 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 consists of an emitting unit VEGAMIP T61 and a
receiving unit VEGAMIP R62 with external housing.

5 Encapsulated horn antenna with PTFE cover
Functional principle
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.
3.3 Packaging, transport and storage
Packaging
Transport
Transport inspection
41912-EN-120228
VEGAMIP R62 • - Relay 9
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 environmentfriendly, recyclable cardboard. For special versions, PE foam or PE foil
is also us ed. 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.

Up to the time of installation, the packages must be left closed and
stored according to the orientation and storage markings on the
outside.
Unless otherwise indicated, the packages must be stored only under
the following conditions:
l Not in the open
l Dry and dust free
l Not exposed to corrosive media
l Protected against solar radiation
l Avoiding mechanical shock and vibration
l Storage and transport temperature see chapter "Supplement -
Technical data - Ambient conditions"
l Relative humidity 20 … 85 %
3.4 Accessories and replacement parts
The protective cover protects the sensor housing against soiling and
intense heat from solar radiation.
You will find additional information in the supplementary instructions
manual "Protective cover" (Document-ID 34296).
Flanges are available in different versions according to the following
standards: DIN 2501, EN 1092-1, ANSI B 16.5, JIS B 2210-1984,
GOST 12821-80.
You can find additional information in the supplementary instructions
manual "Flanges according to DIN-EN-ASME-JIS" (Document-ID
31088).
Electronics module

Mounting adapter
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).

Moisture
Switching point
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.
4.2 Instructions for installation
If possible, install VEGAMIP 62 in a position where a high 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.

Product strength
The VEGAMIP 62 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
Inflowing medium
If VEGAMIP 62 is mounted in the filling stream, unwanted false
measurement signals can be generated. For this reason, mount
VEGAMIP 62 at a position in the vessel where no disturbances, e.g.
from filling openings, agitators, etc., can occur.
Non-metallic vessels
Microwaves can penetrate non-conductive materials. Hence, it is
possible to measure through the wall of non-conductive vessels.

Metal vessels
In metal vessels, you have to mount VEGAMIP 62 on flanges or
threaded sockets. It is also possible to measure through a window. In
general, all products such as glass, ceramic and plastic are suitable as
window material.
Max. thickness of the window material:
Type of material Window material Max. thick-

Concrete vessel
In general, the same as for metal vessels applies to concrete vessels
due to the steel braining.
Wood vessels
In general, the same as for metal vessels applies to wood vessels due
to the liquid absorption of the wood.
Pipelines
VEGAMIP 62 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.

2 To screw VEGAMIP 62 in, use the instrument hexagon (3) below
the housing.
Screw the instrument in and hand-screw it a flat wrench
3 Turn the sensor back (max. 180°) to reach the required orientation
of the polarisation marking (4)
4 Hold the instrument in this position and tighten with the counter nut

Caution:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Note:
In the case of VEGAMIP 62 with NPT thread, the instrument seals in
the thread itself. Hence, no counter nut is necessary for these
versions.
Buildup
Avoid long sockets in which the medium can remain and if possible,
mount VEGAMIP 62 front-flush. This applies mainly if buildup and dust
are expected.
