VEGA VEGAPULS 81 - Manual (Page 15)

VEGAPULS 64 and 81 15
Types and versions: Configuration of measuring systems
Measuring system with 1 … 5 VEGAPULS 81 sensors (type B) per
two-wire line on the processing system VEGALOG 571
• Digital output signal; signal processing in the processing system.
• Up to five sensors on one two-wire line; 15 sensors (in three groups with five sensors each) on
one input card. The two-wire line transmits the power supply, the digital output signal as well
as the superimposed adjustment signal.
• Approved in Ex Zone 0, supply/output signal in EEx e (increased safety).
• Adjustment and parameter adjustment via a PC and the adjustment program VVO. The PC is
directly connected to the computer module of the processing system via an interface cable
(RS 232).
• An indicating instrument with digital and analogue indication is optionally integrated in the
sensor.
• Optionally an external digital/analogue indication. The indication can separated from the sen-
sor in Ex zone 0 up to 25 m.
• The max. permissible resistor of the two-wire signal and supply line is 15 Ω per wire or max.
1000 m cable length between processing system and sensor.
