3.2Principle of operation
VEGACAL 67 is a level sensor with partly insulated electrode
for continuous level measurement under high process tem-
peratures.
The electronics functions acc.to the admittance principle
(phase-selective admittance processing).
It is designed for industrial use in all areas of process
technology and can be applied in all areas of industrial process
measurement.

31760-EN-060306

Probes such as VEGACAL 67 are used in solids applications.
The range of the process temperature is -50 …300°C
(-58 …572°F). With remote housing -50 …400°C
(-58 …752°F).
The probe,the measured product and the vessel wall form an
electrical capacitor.The capacitance is influenced by three
main factors.

Fig.2:Functional principle -Plate capacitor
1Distance between the electrode surfaces
2Size of the electrode surfaces
3Type of dielectric between the electrodes
The probe and the vessel wall are the capacitor plates.The
measured product is the dielectric.Due to the higher dielectric
constant (DK value)of the product compared to air,the
capacitance increases as the probe is gradually covered.
The capacitance as well as the resistance change are
converted in the oscillator into a level-proportional signal.
Power is supplied via the H1Fieldbus.Atwo-wire cable acc.to
Fieldbus specification serves as carrier of both power and
digital data transmission 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 acc.to IEC 61158-2:

tion Fieldbus)communication network are available in the

appropriate certificates are also available there.ACDwith the
appropriate files and certificates can be ordered via e-mail
under [e-mail] or by phone from one of the VEGA
agencies under the order number "DRIVER.S".
The optional heating requires an own supply voltage.Details

3.3Adjustment
VEGACAL 67 can be adjusted with three different adjustment
media:
lthe indicating and adjustment module PLICSCOM
lthe suitable VEGA DTM in conjunection with an adjustment
software acc.to the FDT/DTM standard,e.g.PACTware™
and PC

The entered parameters are generally saved in VEGACAL 67,
optionally also in PLICSCOM or in PACTware™.
3.4Storage and transport
Your instrument was protected by packaging during transport.
Its capacity to handle normal loads during transport is assured
by a test acc.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.

4Mounting
4.1General 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°).
With screwed versions,the housing must not be used for
screwing in!Tightening can cause damages on the locking
piston of the housing.
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 VEGACAL 67 additional protection against
moisture penetration by leading the connection cable down-
ward in front of the cable entry.Rain and condensation water
can thus drain off.This applies mainly to mounting outdoors,in
areas where moisture is expected (e.g.by cleaning processes)
or on cooled or heated vessels.
Fig.3:Measures against moisture penetration
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.
The max.permissible pressure is stated in the "Technical
data"in the "Supplement"or on the type label of the sensor.

Insulating measures,such as e.g.covering the thread with
teflon tape,can interrupt the necessary electrical connection
with metal vessels.For this reason,ground the probe on the
vessel or use a conductive seal material.
Metal vessel
Make sure that the mechanical connection of the probe to the
vessel is electrically conductive to ensure sufficient grounding.
Use conductive seals such as e.g.copper or lead etc.
Insulating measures,such as covering the thread with Teflon
tape,can interrupt the necessary electrical connection with
metal vessels.For this reason,ground the probe on the vessel
or use a conductive seal material.
Non-conductive vessel
In non-conductive vessels,e.g.plastic tanks,the second pole
of the capacitor must be provided separately,e.g.in the form
of a concentric tube.
If possible,the capacitive probe should be mounted vertically
or parallel to the counter electrode.This applies particularly to
applications in non-conductive products.
In cylindrical tanks,spherical tanks or other asymmetrical tank
forms,nonlinear level values are generated due to the varying
distance to the vessel wall.
Use a concentric tube in non-conductive products or linearize
the meas.signal.
4.2Mounting information
IfVEGACAL 67 is mounted in the filling stream,unwanted
switching signals may be generated.Mount VEGACAL 67 at a
location in the vessel where no disturbing influence from e.g.
filling openings,agitators,etc.can occur.
This applies particularly to instrument versions with a longer
probe.

Make sure that the max.permissible tensile load of the
suspension cable is not exceeded.The danger of this
happening exists particularly with very heavy solids and large
meas.lengths.The max.permissible load is stated under
"Technical data"in the "Supplement".

5Connecting to power supply
5.1Preparing the connection
Always observe the following safety instructions:
lConnect only in the complete absence of line voltage
lIf overvoltages are expected,overvoltage arresters should
be installed acc.to Foundation Fieldbus specification.
VEGACAL 67 requires a power supply of 9…32 VDC.Power
and the digital bus signal are carried on the same two-wire
connection cable.Power supply via the H1power supply.
VEGACAL 67 is connected with screened cable acc.to the
Fieldbus specification.An outer cable diameter of 5…9mm
ensures the seal effect of the cable gland.
Please make sure that your entire installation is carried out
acc.to the Fieldbus specification.In particular,make sure that
the termination of the bus is done with appropriate terminating
resistors.
OnVEGACAL 67 with cable gland ½NPT and plastic housing,
a metal ½" threaded insert is moulded in 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 affecting the connection between
threaded insert and housing.This will influence the stability of
the connection and the tightness of the housing.
In 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).
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). The low

frequency potential equalisation currents are thus suppressed,
but the protective effect against high frequency interference
signals remains.
5.2Connection steps
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)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 following illustration)
7Insert the wire ends into the open terminals according to
the wiring plan
Fig.5:Connection steps 6and 7
8Press the opening lever of the terminals downward,you will
hear the terminal spring closing
9Check the hold of the wires in the terminals by lightly
pulling on them
