must be carried out only by trained specialist personnel
authorised by the operator.For safety and warranty reasons,
any internal work on the instruments must be carried out only
by personnel authorised by the manufacturer.
2.2Appropriate use
VEGAFLEX 67 is a sensor for continuous interface measure-
ment in liquids.
Detailed information on the application range of VEGAFLEX 67
is available in chapter "Product description".
2.3Warning about misuse
Inappropriate or incorrect use of the instrument can give rise to
application-specific hazards,e.g.vessel overfill or damage to
system components through incorrect mounting or adjustment.
2.4General safety instructions
VEGAFLEX 67 is a high-tech instrument requiring the strict
observance of standard regulations and guidelines.The user
must take note of the safety instructions in this operating
instructions manual,the country-specific installation standards
(e.g.the VDE regulations in Germany)as well as all prevailing
safety regulations and accident prevention rules.
2.5CE conformity
VEGAFLEX 67 is in CE conformity with EMC (89/336/EWG)
and LVD (73/23/EWG).
Conformity has been judged according to the following
standards:
lEMC:

2.6Fulfilling NAMUR recommendations
With regard to interference resistance and interference
emission,VEGAFLEX 67 fulfils NAMUR recommendation
NE 21.
VEGAFLEX 67 and its indicating and adjustment components
fulfill NAMUR recommendation NE 53 in respect to compat-
ibility.VEGA instruments are generally upward and downward
compatible:
lSensor software to DTM VEGAFLEX 67 HART,PA or FF
lDTM VEGAFLEX 67 for adjustment software PACTware™
lIndicating and adjustment module for sensor software
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 VEGAFLEX 67 can be determined as
follows:
lvia PACTware™
lon the type label of the electronics
lvia the indicating and adjustment module

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 explosion protection during operation:
lOperate the 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 there is no explosive atmosphere present if you
intend to operate the instrument with opened 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 way that the sensor cannot
touch the vessel wall or vessel installations.Keep in mind
the influence of product movement in the vessel.
lThe surface temperature of the housing must not exceed
the ignition temperature of the surrounding explosive
atmosphere
This instrument was assessed by a person who fulfils the DIN
EN 60079-14 requirements.
2.9Environmental 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

3.2Principle of operation
VEGAFLEX 67 is a level sensor with coax,rod or cable probe
for continuous interface measurment.
It is designed for industrial use in all areas of process
technology and can be used in liquids.
High frequency microwave impulses are guided along a steel
cable or rod or a rod inside a steel tube.When reaching the
product surface,a part of the microwave impulses is reflected.
The other part passes the upper product and is reflected a
second time by the interface.The running times to the two
product layers are processed by the instrument.
Upper medium (L2)
lThe upper medium must not be conductive
