Measuring range
VEGAFLEX 55 0.1 ... 4 m
Output signal
digital (Profibus) Two-wire technology:
The digital output signal (measuring signal) is
modulated onto the power supply and further
processed in the PLC or process control room .
Integration time 0 … 999 seconds (adjustable)
Adjustment
- adjustment software VEGA Visual Operating on Master-Class 2 PC
- adjustment module MINICOM in the sensor or in the external instrument (optional)
- process adjustment interface PACTware
TM (under which VVO runs as a subprogram)
- SIMATIC PDM in conjunction with Electronic Device Description (EDD)
