Measuring system with VEGAPULS 56K Ex, 56K Ex0 via a separator
(Smart-Transmitter) on passive DCS
• Two-wire technology (loop powered), intrinsically safe ia-supply via the signal line of the sepa-
rator for operation of the sensor in Ex-zone 1 (VEGAPULS 56K Ex) or in zone 0 (VEGAPULS
56K Ex0)
• Output signal sensor 4 … 20 mA passive
Output signal separator 4 … 20 mA active
• Optionally external indicating instrument with analogue and digital indication (can be mounted
up to 25 m separated from the sensor in Ex-area)
• Adjustment with PC, HART
®
-handheld or adjustment module MINICOM (can be plugged into
the sensor or into the external indicating instrument VEGADIS 50)
• Max. signal line resistor 15

4␣ …␣ 20␣ mA active means that the
separator delivers level depend-
ent a current of 4␣ …␣ 20␣ mA. The
separator reacts then electrically
against the DCS like a current
source.
