3 .2 Principle of operation
VEGAFLEX 66 is a level sensor with coax, rod or cable probe for
continuous level measurement in products with temperatures between
-20 °C
and +250 °C (-4 … +482 °F).
I t is designed for industrial use in all areas of process technology and
can be used in liquids.
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.
