High 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.
Power supply via the Profibus DP/PA segment coupler or VEGALOG
571 EP cards. A two-wire cable according to Profibus specification
serves as carrier of both power and digital data transmission for
multiple sensors. The instrument profile of VEGAFLEX 66 corresponds
to profile specification version 3.0.
The backlight of the indicating and adjustment module is powered by
the sensor. Prerequisite is a certain level of operating voltage.
The data for power supply are specified in chapter "Technical data".
