3.2 Principle of operation
The VEGAFLEX 82 is a level sensor with cable or rod probe for con-
tinuous level measurement, suitable for applications in bulk solids.
DuetothequalicationuptoSIL2orhomogeneousredundantupto
SIL3 (IEC 61508) the VEGAFLEX 82 is suitable for the use in safety-
instrumented systems (SIS).
The safety function (SIF) can be a monitoring of the max. or min. level
or a combination of both.
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.
