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"or 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
sealing surface of the thread or flange.
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 (dead band). Keep 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".
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.
4.2Mounting 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 min.distance (lower dead band)is
stated in chapter "Technical data".
Fig.3:Vessel with conical bottom
Make sure that the probe is not subjected to strong lateral forces.
Mount VEGAFLEX 66 at a position in the vessel where no
disturbances,e.g.from filling openings,agitators,etc., can occur.

34169-EN-100426

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 1m(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.
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).
IfVEGAFLEX 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).
Aspecial high temperature version of VEGAFLEX 66 with integrated
bypass tube can be used in applications with temperatures up to
400 °C(752 °F).
Keep in mind that buildup can form on the spacers.Strong buildup can
influence the measurement.

Note:
Measurement in a standpipe is not recommended for very adhesive
products.
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
(optional) - (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 insulation.This
prevents the electronics from strong heating or cooling by temperature
radiation.
Make sure that with heated or cooled vessels the permissible ambient
temperature on the housing is not exceeded.The permissible ambient
temperature is stated in chapter "Technical data"under "Ambient
conditions".

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
Tip:
We recommend using VEGA overvoltage arresters B63-48 and
ÜSB 62-36G.X.
Inhazardous 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 two-wire
cable.The voltage supply range can differ depending on the
instrument version.
The 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 and VEGASCANs meet this requirement.
Keep in mind the following additional influences on the operating
voltage:
lOutput voltage of the power supply unit can be lower under
nominal load (with a sensor current of 20.5mAor 22 mAin case of
fault message)
lInfluence of additional instruments in the circuit (see load 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.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.
We generally recommend the use of screened cable for HART
multidrop mode.
On the instrument with cable entry ½NPT and plastic housing there is
a metallic ½" threaded insert moulded into the plastic housing.

Caution:
Nogrease 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.1nF,
1500 V). The low frequency potential equalisation currents are thus
suppressed,but the protective effect against high frequency interfer-
ence signals remains.
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 slightly 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
