3.2 Principle of operation
VEGACAL 63 is a level sensor with fully insulated probe for continuous level measurement.
The electronics functions according 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.
Fully insulated probes such as VEGACAL 63 are preferably used in
conductive liquids.
Probe, measured product and vessel wall form an electrical capacitor.
The capacitance is inuenced by three main factors.

Fig. 3: Functional principle - Plate capacitor
1 Distance between the electrode surfaces
2 Size of the electrode surfaces
3 Type of dielectric between the electrodes
The probe and the vessel wall are the capacitor plates. The measured
product and the insulation are the dielectric. Due to the higher dielectric constant of the insulation and the conductive product compared to
air, the capacitance increases as the probe is gradually covered.
The capacitance as well as the resistance change are converted by
the electronics module into a level-proportional signal.
Power supply and bus
communication
GSD/EDD
30028-EN-130917
VEGACAL 63 • Probus PA
Power supply via the Probus DP/PA segment coupler or VEGALOG
571 EP cards. A two-wire cable according to Probus specication

Screwed anges are available in dierent versions according to the
following standards: DIN 2501, EN 1092-1, BS 10, ANSI B 16.5,
JIS B 2210-1984, GOST 12821-80.
You can nd additional information in the supplementary instructions
manual "Flanges according to DIN-EN-ASME-JIS" (Document-ID
31088).
Condensation
In case of strong condensation, the draining of condensed water
can change the measurement accuracy. The suitable version is the
Screening against condensation. The condensation can drain o
outside on the screening tube adapter.
Typical applications of the screening tube adapters are e.g. for
condensation or sockets. Apart from the standard version, there is
a second version for vacuum with a sepcial seal. When the screening tube adapter is submerged in liquid, we recommend the use of a
vacuum-tight version.
Socket
In case of long sockets, the screening tube can increase the sensitivity of the probe by compensating the inuences of the socket. The
suitable version is Capacitive screening, vacuum-tight.
When the probe is mounted laterally, buildup can accumulate in the
socket. A screening tube makes the covered part of the probe inactive
and hence insensitive to inuence from buildup and socket. Hence,
the screening tube adapter excludes changing inuences caused by
the medium and ensures stable measurement conditions. The suitable version is Capacitive screening, vacuum-tight.

4.1 General instructions
Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
process tting, are suitable for the existing process conditions, such
as process pressure, process temperature as well as the chemical
properties of the medium.
You can nd the specications in chapter "Technical data" and on the
nameplate.
Installation position
Welding work
Handling
Moisture
Select an installation position you can easily reach for mounting and
connecting as well as later retrotting of a display and adjustment
module. The housing can be rotated by 330° without the use of any
tools. You can also install the display and adjustment module in four
dierent 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 o. 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.
Pressure/Vacuum

Fig. 4: Measures against moisture penetration
The process tting 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 specied in chapter "Technical
data" or on the type label of the sensor.
Insulating measures, such as e.g. covering the thread with teon 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.
Vessel material
Vessel forms
Installation position
Metal vessel
Make sure that the mechanical connection of the probe to the vessel
is electrically conductive to ensure sucient grounding.
Use conductive seals, such as those made of copper or lead, etc.
Insulating measures, such as covering the thread with Teon 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-conductivevessels
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.
4.2 Mounting instructions
During operation, the probe must not touch any installations or the
vessel wall. The measured value can also change if the distance to
the vessel wall changes considerably. If necessary, secure the end of
the probe (insulated).

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.
If the instrument is mounted in the lling stream, unwanted false
measurement signals can be generated. For this reason, mount the
instrument at a position in the vessel where no disturbances, e.g. from
lling openings, agitators, etc., can occur.
This applies particularly to instrument versions with a longer probe.

5.1 Preparing the connection
Always keep in mind the following safety instructions:
Connect only in the complete absence of line voltage
•
If voltage surges are expected, overvoltage arresters should be
•
installed according to Probus specications
Tip:
We recommend VEGA overvoltage arrester B63-32.
In hazardous areas you must take note of the respective regulations,
conformity and type approval certicates of the sensors and power
supply units.
Voltage supply
Connection cable
Cablegland½NPT
Cable screening and
grounding
Power is supplied via a Probus DP/PA segment coupler or a VEGALOG 571 EP input card. The power supply range can dier depending
on the instrument version.
The data for power supply are specied in chapter "Technical data".
Connection is made with screened cable according to the Probus
specication. Power supply and digital bus signal are carried over the
same two-wire connection cable.
Use cable with round cross-section. A cable outer diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal eect of the cable gland.
If you are using cable with a dierent diameter or cross-section,
exchange the seal or use a suitable cable gland.
Please make sure that your installation is carried out according to the
Probus specication. In particular, make sure that the termination of
the bus is done with appropriate terminating resistors.
On the instrument with cable entry ½ NPT 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 inuence 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).
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
