3.2 Principle of operation
The VEGAFLEX 83 is a level sensor with polished rod probe for
continuous level or interface measurement, particularly suitable for
applications in the food processing and pharmaceutical industry.
Optionally an autoclaved version with separable housing is available.
High frequency microwave pulses are guided along a steel cable or
a rod. Upon reaching the product surface, the microwave pulses are
reflected. The running time is evaluated by the instrument and output-
ted as level.
