Operating Instructions
1 DFON display
2 Connection for temperature and relay signal
3 Thread for mounting the AFIx
4 Hole for medium (conductivity measuring)
5 Tip with temperature sensor
6 Measuring cell
7 Connection for power supply, conductivity/
concentration signal and IO-Link
The CombiLyz AFIx consists of a conductivity
sensor, temperature sensor and a transmitter.
The device measures conductivity/concentration
and temperature of liquid media.
The CombiLyz AFIx can be programmed via the
touch screen display, FlexProgrammer 9701 or
an IO-Link Master. During operation, the display
shows information regarding measured values,
alarms and other data as specified during setup.
The 2 connectors are used to transfer sensor data,
alarms, control signals and programming data.

7 Medium
8 Primary coil
Around the hole inside the measuring cell there
are 2 coils. The primary coil is supplied with
AC voltage and the secondary coil measures
the inducted current in the liquid medium inside
the hole. The temperature of the liquid medium
is measured via a Pt100 sensor in the tip of
the measuring cell. This allows temperature
compensation of the conductivity signal.
