Measuring system with 1 … 2 VEGAPULS 56V on signal conditioning instrument
VEGAMET 515V
• Two-wire technology, supply from the signal conditioning instrument; output signals and
voltage supply via one two-wire line
• Digital output signal, two sensors on one line
• Measured value indication in the sensor and in the signal conditioning instrument
• Optionally external indicating instrument (can be mounted up to 25 m separated from the
sensor in Ex-area)
• Adjustment with PC, signal conditioning instrument or adjustment module MINICOM (can be
plugged into the sensor or into the external indicating instrument VEGADIS 50)
• Max. resistance of the signal line 15
Ω
per wire or 1000␣ m cable length

1) Sensor lines should be looped in screened cables.
Earth the cable screens on the processing system
or better on the sensor. In case of stronger
electromagnetic interferences it is useful to earth
the cable screens on both ends. However it must
be noted that no earth compensation currents flow
via the screens. In case of earthing on both sides
earth compensation currents are avoided by
connecting the cable screen on one earth side
(e.g. in the switching cabinet) via a capacitor (e.g.
0,1␣
µ
F; 250␣ V) to the earth potential.
