CombiLyz AFI4 conductivity transmitter is a compact sensor/transmitter,
based on inductive technology, which is designed and produced to meet
the requirements in hygienic and general industry where measuring of
medium range conductivity is used.

Description

CombiLyz AFI4 consists of a conductivity sensor and a transmitter built

into one compact unit.

The output from the transmitter are two 4...20 mA, which is available for
both conductivity, concentration and temperature.

The display features more user selectable modes and user specified
“product labels” and warnings. Further there are two switch outputs for
alarms or control.

The background colour can be set in three colours, white, green or red

- steady or flashing, controlled by the alarm settings. The transmitter and
display can be programmed by either the touch screen on the display or
by the FlexProgrammer programming unit and software.

Safety instruction

This instrument is built and tested according to the current EU-directives
and packed under technically safe conditions. In order to maintain these
conditions and to ensure safe operation, the user must follow the hints
and warnings given in this instruction.

During the installation the valid national rules have to be observed. Ig­noring the warnings may lead to severe personal injury or substantial
damage of property.

The product must be operated by trained staff. Correct and safe opera­tion of this equipment is dependent on proper transport, storage installa­tion and operation.

All electrical wirings must conform to local standards. In order to prevent
stray electrical radiation, we recommend twisted and shielded input
cables and also to keep power supply cables separated from the input
cables. The connection must be made according to the connection dia­grams.

Before switching on the power supply take care that other equipment is
not affected. Ensure that the power voltage, the conditions are the envi­ronment comply with the specification of the device.

Before switching off the power supply voltage, check the possible effects
on other equipment and the processing system.

WARNING

The device is not approved for electrical installations in explosion proof
areas.

After mounting of the device - do check that the housing has a ground
potential.

The product contains no direct replaceable parts, except for the DFON
display. In case of malfunction the product must be sent to Baumer for
repair.

Working principle

The measuring cell is a homogeneous sealed body all in PEEK.
Through the body is a hole, through which the media is flowing. Built-in
around the hole are two coils; a primary coil supplied with an AC volt­age and a secondary coil, which picks up a small signal through the
media inducted voltage. The size of this voltage is dependent on the
conductivity of the media. This signal is handled and amplified in the
electronics to a linear analogue 4...20 mA output signal. Also built into
the body is a Pt100 sensor placed in the tip of the sensor. This is meas­uring the media temperature to enable temperature compensation of
the conductivity signal, which is very temperature dependent. The
Pt100 sensor signal also features an analogue 4...20 mA output signal.

The coils and sensor are encapsulated in the PEEK sensor body, which
have a surface with surface roughness (Ra) <0,8 µm. It is therefore well
suited for use in hygienic processes or direct in concentrated acids or
alkalis.

Set-up the AFI4

Conductivity measurement is very temperature dependent.

The factory set-up is 2,0%/°C.

This means that the AFIx will automatically compensate with this fac­tor. If the temperature dependence is known for the media this factor
must be set. However if the factor is unknown, it is recommended to
use an average from above table.

It is possible to adjust the temperature compensation factor from 0,0 …
5,0 %/°C.

Configure the temperature compensation by the touch screen:

Configure the range by the touch screen:

Configuration by the FlexProgram and FlexProgrammer please see
HELP in the FlexProgram.

Concentration output can also be selected by the touch screen or pro­grammed by the FlexProgram.

Programming of the display colours, warnings and relays can be done
by the touch screen (see page 8 and 9) or by the FlexProgrammer.

Mounting

Installation of 3A approved and EHEDG certified products:

1) Use only a 3A approved counter part

2) The inspection hole should be visible and drained

3) Mount the adapter in a self drained position/angle

4) Level the inner surface of the pipe with the counter part.

Example with

PM023 or PM053

Operators Instruction

5) The 3A mark or the arrow shall be placed upwards

6) Welding should be grinded to Ra= 0.8

7) Tighten the swirling nipple on the AFIx 20...25 Nm

8) Installed with correct torque the electrical connection
will point downwards

WARNING

Cannot be
drained



Example

with PM060-1



After installation

 Check the leak tightness of the sleeve.

 Leakage indication hole

must be places downwards

 Check the tightness of glands or M12 plugs.

 Check the tightness of the cover

The hole through the sensor must be in the flow direction

The marks on the
connection must
point in flow direction

There must be some bi-directional flow through the hole to ensure a
homogeneous media - i.e. correct measurement. There must be no
air-bubbles in the hole.

Example

with PM060-2

incorrect



The sensor must be fully submersed in the media.

To avoid turbulence problems the sensor is recommended to mount in
a distance of >1 meter from a bend.

Setting of Temperature compensation for each range.
This will be factory set to 2%/°C as default.

If the box Advanced is ticked, it will be possible to enter an
other target temperature. This is as default set to 25°C, which is the
most common target temperature for most media. If another target
temperature is wanted, it can be entered.
NOTE:

This is not the specific media temperature, but the
“0-point” for the temperature compensation.

When the “Advanced” is ticked the “Compensation temperature
source” is accessible.

You can enter a value to the column %/K2 you will create a unlinear
curve.

These fields are not necessary to change for standard measurement.
Be careful if changing the default values, as wrong values in those
fields may course wrong measurement.

It is possible to select from where the temperature measuring shall
come from

Sensor tip (built in Pt100)

Fixed (no temperature measurement)

Screen Input (when concentration is selected in DTM setup)

No settings in this screen will be available as standard.
When user defined concentration is selected in screen concentration,
it will be possible to adjust temperature concentration.
The default setting will be 2%/°C.

There is 4 selectable medias, for which the calibration curves
is default entered from factory.
