The parameter adjustment of the basic sensor functions is
independent of the software version.The range of available
functions depends on the respective software version of the
individual components.
The software version of VEGACAL 67 can be determined as
follows:
lvia PACTware™
lon the type label of the electronics
lvia the indicating and adjustment module PLICSCOM

2.7Manufacturer declaration
In conformity with DIN EN 60079-14/2004,para.5.2.3,point
c1,the capacitive probe VEGACAL 67 is suitable for use in
zone 2.
The operator must use the instrument correctly and follow the
specifications of the following documents:
lthis operating instructions manual
lthis manufacturer declaration (24639)
lthe applicable installation regulations
Max.increase of the surface temperature during operation:
15 K(individual components in the instrument)
With an ambient temperature of +70°C(+158°F)on the
housing and a process temperature of +70°C(+158°F), the
max.ambient temperature during operation is +85°C(+185°F).
Measures to maintain the explosion protection during oper-
ation:
lOperate you instrument in the range of the specified
electrical limit values.Permissible supply voltage:see
"Technical data"
lMount and operate the instrument in such a way that no
ignition danger is expected by electrostatic charges.The
process fitting,the plastic-coated/covered probe part or the
housing are made of electrically non-conductive plastic
(depending on the version).

lMake sure that the seal is mounted correctly between
lower part of the housing and cover.Screw the cover on
tightly.
lMake sure that there is no explosive atmosphere,if you
want to operate the instrument with open cover
lMake sure that the cable gland is tight and strain-relieved.
The outer diameter of the connection cable must be
adapted to the cable gland.Tighten the pressure screw of
the cable gland carefully.
lCover unused openings for cable glands tightly
lMount the instrument in such a position that the sensor
cannot touch the vessel wall or vessel installations.Keep
the influences of product movements in the vessel in mind.
lThe surface temperature on the housing must not exceed
the ignition temperature of the concerned explosive
atmosphere
This instrument was judged by a person that fulfils the
requirements acc.to DIN EN 60079-14.
2.8Environmental instructions
Protection of the environment is one of our most important
duties.That is why we have introduced an environment
management system with the goal of continuously improving
company environmental protection.The environment man-
agement system is certified acc.to DIN EN ISO 14001.
Please help us fulfil this obligation by observing the environ-
mental instructions in this manual:
lChapter "Storage and transport"
lChapter "Disposal"

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.

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:
The DD (Device Descriptions)and CFF (capability files)
necessary for planning and configuration of your FF (Founda-
tion Fieldbus)communication network are available in the
