3 sensors per two-wire line via
separator VEGATRENN 548 V Ex on the processing system VEGALOG 571
• Two-wire technology, voltage supply and digital output signals via one
two-wire line from the separator
• Three sensors on one two-wire line
• Meas. value indication integrated in the sensor
• Optionally external indicating instrument (can be mounted up to 25 m
separated from the sensor in Ex-area).
• Adjustment with PC or adjustment module (pluggable in the sensor or in
external indication instrument)
• Max. resistance of the signal line 7,5
Ω per wire or 1000 m cable length
(see approval certificates of the separators).
