3.2 Principle of operation
VEGAFLEX 61 is a level sensor with cable or rod probe for continuous
level measurement.
It is designed for industrial use in all areas of process technology and
can be used equally well in liquids or solids.
High frequency microwave pulses are guided along a steel rope or a
rod. Upon reaching the product surface, the microwave pulses are
reflected. The running time is evaluated by the instrument and
outputted as distance.
Power supply via the Profibus DP/PA segment coupler or VEGALOG
571 EP cards. A two-wire cable according to Profibus specification
serves as carrier of both power and digital data transmission for
multiple sensors. The instrument profile of VEGAFLEX 61 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 spec ified 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
from the download section on the VEGA homepage
www.vega.com
under "Services - Downloads - Software - Profibus". There you can
also find the appropriate certificates. In a PDM environment, an EDD
(Electronic Device Description) is also required to enable the full range
of sensor functions (also available as a download).A CD with the
appropriate files can be ordered via e-mail under info@de.vega.com or
by phone from one of the VEGA agencies under the order number
"DRIVER.S".
