High frequency microwave pulses are guided along a steel
rope or a rod. Upon reaching the product surface, the
microwave pulses are reflected. The running time is evaluated
by the instrument and outputted as distance.

measured value transmission over the same cable.
The supply voltage range can differ depending on the
instrument version.
Data for power supply are specified in chapter "Technical
data".
The backlight of the indicating and adjustment module is
powered by the sensor. The prerequisite for this is a supply
voltage at a certain level. The exact voltage specifications are
stated in chapter "Technical data".
The optional heating requires its own power supply. You can
find further details in the supplementary instructions manual
"Heating for indicating and adjustment module".
This function is generally not available for approved instruments.

aging, 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 environ-
ment-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.
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
l Dry and dust free
l Not exposed to corrosive media
l P
l Avoiding mechanical shock and vibration
l Storage and transport temperature see "Supplement -

4.1 General instructions
Select
an installation position you can easily reach for
mounting and connecting as well as later retrofitting of an
indicating and adjustment module. The housing can be rotated
by 330° without the use of any tools. You can also install the
indicating and adjustment module in four different positions
(each displaced by 90°).
Before beginning the welding work, remove the oscillator
(electronics) from the sensor. By doing this, you avoid damage
to the electronics through inductive coupling.
With threaded versions, the housing must not be used to screw
in the instrument! Applying tightening forces on the housing
can damage its internal parts.
Use the hexagon for screwing in.
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.

in mind that the cable length cannot be used all the way to the
end because measurement in the area of the gravity weight is
not possible. These min. distances (dead bands) are listed in
chapter "Technical data".
Pressure
Mounting position
The process fitting must be sealed if there is gauge or low
pressure in the vessel. Before use, check if the seal material is
resistant against the measured product and the process
temperature.
The max. permissible pressure is specified in chapter
"Technical data" or on the type label of the sensor.
4.2 Mounting instructions
Mount VEGAFLEX 66 in such a way that the distance to vessel
installations or to the vessel wall is at least 300 mm (12 in).
During operation, the probe must not touch any installations or
the vessel wall. If necessary, fasten the probe end.
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 bottom. When
using the cable version, keep in mind that measurement down
to the tip of the probe is not possible. The exact value of the

Fig. 3: Vessel

Standpipes or bypass tubes are normally metal tubes with a
diameter of 30 … 200 mm (1.18 … 7.87 in). In measurement
technology such a tube corresponds to a coax probe. It does
not matter if the standpipe is perforated or slotted for better
mixing. Lateral inlets with bypass tubes also do not influence
the measurement.
Measuring probes can be mounted in bypass tubes up to
DN 200.
The max. temperature is 250 °C (482 °F).
If VEGAFLEX 66 is used in standpipes or bypass tubes,
contact with the tube wall should be avoided. We offer spacers
as accessories for fastening the probe in the middle of the
tube.
Depending on the tube diameter or tube length, one or several
spacers can be mounted. With cable probes, the cable can
also be strained to avoid contact with the tube.
The max. temperature for the spacers is 250 °C (482 °F).
A special high temperature version of VEGAFLEX 66 with
integrated bypass tube can be used in applications with
temperatures up to 400 °C (752 °F).

Excessive system vibration or shocks, e.g. caused by agitators
or turbulence in the vessel (e.g. from fluidisation) can cause
the coax probe of VEGAFLEX 66 to vibrate in resonance.
Should a coax probe of more than 1 m (3.281 in) length should
be used, you can provide a suitable support or guy directly
above the end of the probe to stabilise it.
If there is a danger of the probe touching the vessel wall during
operation due to product movements or agitators etc., the
measuring probe should be securely fixed.
In the gravity weight there is a thread (M12), e.g. for a ring bolt
(article no. 2.27424).
Make sure that the probe cable is not completely taut. Avoid
tensile loads on the cable.
Avoid undefined cable-vessel connections, i.e. the connection
must be either grounded reliably or isolated reliably. Any
deviation from this requirement can lead to measurement
errors.
VEGAFLEX 66 should be integrated in the vessel installation.
This prevents the electronics from strong heating by heat
radiation.

We

In
hazardous areas you should take note of the appropriate
regulations, conformity and type approval certificates of the
sensors and power supply units.
Power supply and current signal are carried on the same twowire cable. The voltage supply range can differ depending on
the instrument version.
Data for power supply are specified in chapter "Technical
data".
Provide a reliable separation between the supply circuit and
the mains circuits according to DIN VDE 0106 part 101. The
VEGA power supply units VEGATRENN 149A Ex, VEGASTAB 690 as well as all VEGAMETs meet this requirement.
Bear in mind the following factors regarding supply voltage:
l Outpu

nominal
load (with a sensor current of 20.5 mA or 22 mA in
case of fault message)
l Influence

values in chapter "Technical data")
The instrument is connected with standard two-wire cable
without screen. If electromagnetic interference is expected
which is above the test values of EN 61326 for industrial areas,
screened cable should be used.
Use cable with round cross-section. A cable outer diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal effect of the cable
gland. If you are using cable with other diameter or crosssection, you have to exchange the seal or use a suitable cable
gland.

On the instrument with cable entry ½ NPT and plastic housing
there is a metallic ½" threaded insert moulded into the plastic

Caution:
No
grease should be used when screwing the NPT cable
gland or steel tube into the threaded insert. Standard grease
can contain additives that corrode the connection between
threaded insert and housing. This would influence the stability
of the connection and the tightness of the housing.
If screened cable is necessary, connect the cable screen on
both ends to ground potential. In the sensor the screen must
be connected directly to the internal ground terminal. The
ground terminal on the outside of the housing must be
connected to the potential equalisation (low impedance).
If potential equalisation currents are expected, the connection
on the processing side must be made via a ceramic capacitor
(e. g. 1 nF, 1500 V). The low frequency potential equalisation
currents are thus suppressed, but the protective effect against
high frequency interference signals remains.

applications. In particular, make sure that no potential equalisation currents flow over the cable screen. In case of
grounding on both sides this can be achieved by the use of a
capacitor or a separate potential equalisation.
