40 VEGAPULS 54K enamel
24 101-EN-041227
Technical data
Measuring range 1)
Standard 0 … 20 m
Output signal
4 … 20 mA current signal in two or four-wire technology
Fault signal current signal 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 trans-
mitted in a cable separate from power supply.
Measured value display (optional)
Liquid crystal indication
- in the sensor scalable output of meas-
ured 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
