3.2Principle of operation
VEGAFLEX 65 is a level sensor with pipe probe for continuous level
measurement.
It is designed for industrial use in all areas of process technology and
can be used in liquids.
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.
Power is supplied via the H1Fieldbus.Atwo-wire cable according to
Fieldbus specification serves as carrier of both power and digital data
for multiple sensors.This cable can be operated in two versions:
lvia an H1interface card in the control system and additional power
supply
lvia a Linking device with HSE (High speed Ethernet)and
additional power supply according to IEC 61158-2

4Mounting
4.1General instructions
Make sure that all parts of the instrument exposed to the process,in
particular the sensor element,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.
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 electronics module
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.

Fig.2:Measures against moisture penetration
The reference plane for the measuring range of the sensors is the seal
surface of the thread.
Keep in mind that a min.distance must be maintained below the
reference plane and possibly also at the end of the probe -
measurement in these areas is not possible.These min.distances are
listed in chapter "Technical data"in the "Supplement".Keep in mind
for the adjustment that the default setting for the measuring range
refers to water.
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.
4.2Instructions for installation
Mount VEGAFLEX 65 in such a way that the probe does not touch any
installations or the vessel wall during installation.

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.
Fig.3:Vessel with conical bottom
Make sure that the probe is not subjected to strong lateral forces.
Mount VEGAFLEX 65 at a position in the vessel where no
disturbances,e.g.from filling openings,agitators,etc., can occur.
Fig.4:Lateral load
Extreme vibration caused by the system,e.g.due to agitators or
turbulence in the vessel from inflowing medium,can cause the coax
probe of VEGAFLEX 65 to vibrate in resonance.With coax probes of
Inflowing medium

5Connecting to power supply
5.1Preparing the connection
Always keep in mind the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltage surges are expected,overvoltage arresters should
be installed according to Foundation Fieldbus specification
Tip:
We recommend VEGA overvoltage arrester B63-32.
In hazardous areas you must take note of the respective regulations,
conformity and type approval certificates of the sensors and power
supply units.
The instrument requires a operating voltage of 9…32 V DC.
Operating voltage and the digital bus signal are carried on the same
two-wire connection cable.Power is supplied via the H1power supply.
Connection is carried out with screened cable according to Fieldbus
specification.
Use cable with round cross-section.Acable outer diameter of 5…9mm
(0.2…0.35 in)ensures the seal effect of the cable gland.If you are
using cable with a different diameter or cross-section,exchange the
seal or use a suitable cable gland.
Make sure that the entire installation is carried out according to the
Fieldbus specification.In particular,make sure that the bus is
terminated with suitable terminating resistors.
On the instrument with cable entry ½NPT and plastic housing there is
a metallic ½" threaded insert moulded into the plastic housing.
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.
With systems with potential equalisation,connect the cable screen
directly to ground potential at the power supply unit,in the connection
box and at the sensor.The screen in the sensor must be connected
directly to the internal ground terminal.The ground terminal outside on
the housing must be connected to the potential equalisation (low
impedance).

5Connecting to power supply
31848-EN-120329

In systems without potential equalisation,connect the cable screen
directly to ground potential at the power supply unit and at the sensor.
In the connection box or T-distributor,the screen of the short stub to
the sensor must not be connected to ground potential or to another
cable screen.The cable screens to the power supply unit and to the
next distributor must be connected to each other and also connected
to ground potential via a ceramic capacitor (e.g.1nF,1500 V). Low-
frequency potential equalisation currents are thus suppressed,but the
protective effect against high frequency interference signals remains.
The total capacitance of the cable and of all capacitors must not exceed
10 nFin Ex applications.
Take note of the corresponding installation regulations for Ex
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.
5.2Connection procedure
Proceed as follows:
1Unscrew the housing cover
2If an indicating and adjustment module is installed,remove it by
turning it to the left.
3Loosen compression nut of the cable entry
4Remove approx.10 cm (4in)of the cable mantle,strip approx.
1cm (0.4in)of insulation from the ends of the individual wires
5Insert the cable into the sensor through the cable entry
6Lift the opening levers of the terminals with a screwdriver (see
