T he type label contains the most important data for identification and
use of the instrument:
l A
rticle number
l S erial number
l T echnical data
l A rticle numbers, documentation
l SIL identification (with SIL rating ex works)
W ith the serial number, you can access the delivery data of the
instrument via www.vega.com, "VEGA Tools" and "serial number

3 .2 Principle of operation
VEGAFLEX 61 is a level sensor with cable or rod probe for continuous
level measurement.
I t is designed for industrial use in all areas of process technology and
can be used equally well in liquids or solids.
H igh 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.
T wo-wire electronics 4 … 20 mA/HART for power supply and
measured value transmission over the same cable.
