3.2 Principle of operation
The VEGAFLEX 86 is a level sensor with cable or rod probe for
continuous level or interface measurement, particularly suitable for
applications in high temperatures up to +450 °C (842 °F).
High frequency microwave pulses are guided along a steel cable or
a rod. Upon reaching the product surface, the microwave pulses are
reected. The running time is evaluated by the instrument and output-
ted as level.
