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)
Resistance/Load of the signal cable
- 4 … 20 mA two-wire
non-Ex: max 975
Ω
Ex d ia: max. 720
Ω
Ex ia: max. 670
Ω
- 4 … 20 mA four-wire 500

Integration time
- analogue 4 … 20 mA 0 … 999 seconds
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
® handheld
