VEGA VEGASON 51V…53V - Manual (Page 16)

16 VEGASON 51 V … 53 V
Types and versions - Configuration of measuring systems
3 sensors per two-wire line via separator VEGATRENN 548 V Ex on the
processing system VEGALOG 571
• Two-wire technology, power supply and digital output signals via one two-
wire line from the separator.
• Three sensors on one two-wire line.
• Measured 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
(can be plugged in the sensor or external indicating instrument).
• Max. resistance of the signal line 7,5
Ω
per wire or 1000 m cable length,
note the permissible values for capacitance and inductance of the connec-
tion cable (see also approval certificates of the separators).
