GENERAL
The UNIFLEX 2-wire temperature
transmitter with bargraph display is the
solution to requirements regarding
flexibility, reduced stock as approved
safety against electromagnetic
interferences.
By means of a PC and a programming
set the transmitter is programmed for
sensor type, measuring and display
range.
For use within hazardous areas an
intrinsically safe version is available.
DESCRIPTION
The transmitter consists of two
independent signal inputs. One for
thermocouples and one for resistive
temperature sensors.
If thermocouple is selected, the resistive
input is beeing used for connection of
the cold junction compensation sensor
Pt100CJC.
Resistive sensors can be connected in
3-wire configuration.
The bargraph display will be adjusted
within the choosen span to perform
optimal display function.

DISPLAY
Bargraph 51 segments with a resolution
of 2 % for each visible element, respective 1 %, when top segment flashes.
The display is selectable within the
measuring range.
E.g.:
Output signal: 4 mA = 0 °C, 20 mA = 600 °C
Display: 0% = 500 °C, 100 % = 600 °C
