32313-EN-120329

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
lThe dielectric figure of the upper medium must be known (input
required). Min.dielectric figure:rod version 1.7;coax version 1.4.
You can find a list with the dielectric figures on our home page:
www.vega.com
lThe composition of the upper medium must be stable,no varying
products or mixtures
lThe upper medium must be homogeneous,no stratifications within
the medium
lMin.thickness of the upper medium 100 mm
lClear separation from the lower medium,no emulsion phase,no
mull layer
lIf possible,no foam on the surface
Lower medium (L1)
lThe dielectric figure must be 10 higher than the dielectric figure of
the upper medium,preferably electrically conductive.Example:
upper medium dielectric figure 2,lower medium at least dielectric
figure 12

The interface is directly processed by the sensor and outputted as
digital output signal.
The indication of the indicating and adjustment module and PACTware
output the distance to the interface (d1)in m(d).
Power supply via the Profibus DP/PA segment coupler or VEGALOG
571 EP cards.Atwo-wire cable according to Profibus specification
serves as carrier of both power and digital data transmission for
multiple sensors.The instrument profile of VEGAFLEX 67 corresponds
to profile specification version 3.0.
The backlight of the indicating and adjustment module is powered by
the sensor.Prerequisite is a certain level of operating voltage.
The data for power supply are specified in chapter "Technical data".
The optional heating requires its own operating voltage.You can find
details in the supplementary instructions manual "Heating for indicat-
ing and adjustment module".
This function is generally not available for approved instruments.
The GSD (instrument master files)and bitmap files necessary for
planning your Profibus-DP-(PA)communication network are available
