Output signal

Signal output

4 … 20 mA current signal in two-wire or
four-wire technology; the HART

®

signal is

modulated to the 4 … 20 mA signal

Fault signal

current output unchanged, 20.5 mA, 22 mA
(adjustable)

Integration time

0 … 999 seconds (adjustable)

Two-wire technology 4 … 20 mA:
The analogue 4 … 20 mA output signal (measuring signal) is transmitted together with the
power supply via one two-wire cable.

Four-wire technology 4 … 20 mA:
Separate power supply. The analogue 4 … 20 mA output signal (measuring signal) is
transmitted in a cable separate from power supply.

Measured value display (optional)

Liquid crystal indication

- in the sensor

scalable output of measured values as graph
and number

- in the external indicating instrument

powered by the sensor

scalable output of measured values as graph

and number. The display unit can be mounted
up to 25 m away from the sensor

Adjustment

- PC and adjustment software VEGA Visual Operating
- adjustment module MINICOM
- HART
