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.
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.
Probe end tracking
To increase sensitivity, the probe is equipped with probe end tracking.
In products with a low dielectric constant, this function is very helpful.
