VEGA VEGAPULS 81 - Manual (Page 16)

16 VEGAPULS 64 and 81
Types and versions: Configuration of measuring systems
Measuring system with 1 … 15 VEGAPULS 81 sensors (type C) per
two-wire line with separate power supply on the processing system
VEGALOG 571
• Digital output signal; signal processing in the processing system.
• 15 sensors on one two-wire line. The two-wire line transmits the digital output signal as well as
the superimposed adjustment signal of up to 15 sensors. The power supply is made sepa-
rately by a local voltage source.
• Approved in Ex Zone 0. Supply and 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 be separated from the
sensor in Ex zone 0 up to 25 m.
• The max. permissible resistor of the two-wire signal line is 15 Ω per wire or max. 1000 m cable
length between sensor and processing system.
