1. Safety

Intended use

The sensor must be used solely for conductivity

measurements of liquids.

The sensor must only be used for media against

which the housing material and sensor tip are

resistant.

Staff qualication

Only employ staff who are trained for the activities

described. This applies in particular to assembly,

installation, conguration and troubleshooting.

Make sure that the staff have read and understood

these instructions.

Electrical connection and EMC

All electrical wirings must comply with local

standards and connections must be made

according to the connection diagrams.

Technical condition

Only use the sensor in perfect technical condition.

Only use Baumer accessories.

Baumer will accept no liability for other

manufacturers’ accessories.

Only the DFON display may be replaced and only

Baumer may perform repairs on the device.

Operation

The power supply and environmental conditions

must comply with the specications of the

device. The device is not approved for electrical

installations in explosion hazard areas.

Before switching the device on and off, possible

effects on other equipment and the processing

system must be checked.

Risk of burns from hot media

During operation the sensor housing may warm

up to over 50 ºC. When working with hot media

provide protection against burns.

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 specied during setup.

The 2 connectors are used to transfer sensor data,

alarms, control signals and programming data.

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.

5. Mounting

5.1 Mounting conditions

Fig. 3. Mounting locations

The sensor can be mounted at any point on the

vessel or pipe.

Fig. 4. Fully submerged in medium

For correct operation the sensor must be fully

submerged in the medium.

Fig. 5. Mounting in ow direction

To allow a sufcient self-cleaning to happen, the

hole through the sensor must be oriented in the

ow direction. Arrows (1) on the sensor above the

connection mark the orientation of the hole.

≥1 m

Fig. 6. Recommended distance from bend

To avoid problems due to turbulence in owing

media, Baumer recommends to mount the sensor

in a distance of at least 1 m from a bend.

1. Sicherheit

Bestimmungsgemässe Verwendung

Der Sensor darf nur zur Leitfähigkeitsmessung von

Flüssigkeiten benutzt werden.

Der Sensor darf nur für Medien eingesetzt

werden, gegen die das Gehäusematerial und die

Sensorspitze resistent sind.

Personalqualikation

Setzen Sie nur Mitarbeiter ein, die zur

Durchführung solcher Arbeiten ausgebildet

wurden. Dies gilt insbesondere für Montage,

Installation, Konguration und Störungsbehebung.

Sicherstellen, dass das Personal diese Anleitung

gelesen und verstanden hat.

Elektrischer Anschluss und EMV

Sämtliche elektrische Leitungen müssen die

örtlichen Auagen erfüllen und Verbindungen

sind anhand des Verkabelungsdiagramms

durchzuführen.

Technischer Zustand

Den Sensor nur dann benutzen, wenn er sich

in einem einwandfreien technischen Zustand

bendet.

Nur Zubehör von Baumer verwenden.

Für Zubehör anderer Hersteller übernimmt Baumer

keine Haftung.

Nur das DFON-Display kann ersetzt werden, wobei

diese Reparaturarbeiten am Gerät ausschliesslich

Baumer durchführen darf.

Betrieb

Die Stromversorgung und die

Umgebungsbedingungen müssen die

Gerätespezizierungen erfüllen. Das Gerät

darf nicht im Zusammenhang mit elektrischen

Installationen verwendet werden, die sich in

Bereichen benden, in denen Explosionsgefahr

herrscht.

Bevor Sie das Gerät ein- und ausschalten, prüfen

ob eventuelle Auswirkungen auf andere Geräte

und das Prozessverfahren vorhanden sind.

Verbrennungsgefahr bei heissen Medien

Das Gehäuse des Sensors kann sich im Betrieb

auf über 50 °C erwärmen. Bei heissen Medien für

Verbrennungsschutz sorgen.

2 Anschluss für Temperatur- und Relaissignal

3 Gewinde zur Montage des AFIx

4 Bohrung für das Medium (Leitfähigkeitsmessung)

5 Spitze mit Temperatursensor

6 Messzelle

7 Anschluss für Stromversorgung, Leitfähigkeits-/

Konzentrationssignal und IO-Link

Der CombiLyz AFIx besteht aus einem

Leitfähigkeitssensor, Temperatursensor und einem

Messumformer. Das Gerät misst die Leitfähigkeit/

Konzentration und Temperatur von Flüssigstoffen.

Die CombiLyz AFIx kann über das Touch-Display,

den FlexProgrammer 9701 oder einen IO-Link Master

programmiert werden. Während des Betriebs wird

auf dem Display Information über die Messwerte,

Alarme und anderen Daten angezeigt, die während der

Einstellung festgelegt wurden.

Die beiden Steckverbindungen dienen dazu,

Sensordaten, Alarme, Steuersignale und

Programmierdaten zu übermitteln.

7 Medium

8 Primäre Spule

Um die Bohrung herum in der Messzelle benden

sich 2 Spulen. Die primäre Spule wird mit

Wechselspannung gespeist, und die sekundäre Spule

misst den induzierten Strom im Flüssigmedium in der

Bohrung. Die Temperatur des Flüssigkeitsmediums

wird über den Pt100-Sensor an der Spitze

des Messzelle gemessen. Dies gestattet eine

Temperaturkompensation des Leitfähigkeitssignals.
