VEGA VEGASON 54V…56V - Manual (Page 12)

12 VEGASON 54V … 56V
1 … 2 sensors on VEGAMET 515V signal conditioning instrument
• Two-wire technology, supply from the signal conditioning instrument, output signals and
voltage supply via one two-wire cable.
• Digital output signal, two sensors on one cable.
• Display of measured values in the sensor and in the signal conditioning instrument.
• Optional external indicating instrument (can be mounted up to 25 m separated from the
sensor in Ex area).
• Adjustment with the PC, the signal conditioning instrument or adjustment module MINICOM
(can be plugged into the sensor or the external indicating instrument VEGADIS 50).
• Max. resistance of the signal cable 15
W per wire or 1000 m cable length.
1) Sensor cables should be screened. Grounding of
the cable screens at both ends is recommended.
However make sure that no earth compensation
currents flow via the screens
Earth compensation currents can be avoided by
potential equalisation lines or if the cable screen is
grounded at both ends - by connecting one end
(e.g. in the switching cabinet) via a capacitor (e.g.
0.1 µF; 250 V) to earth potential.
