tion on page 17 chapter ‘Technical data’ . Particularly you must meet the requirements
of the ambient temperature and characteristics.
Do not use this product for any other purpose. Improper use and handling can create
hazards and cause damage. For more information, please refer to the safety information in
this instruction manual.
2.2 Personal safety
Please read this instruction manual carefully before commissioning and operating the de-
vice. If you have any questions regarding the product or the application, please don’t hes-
itate to contact M&C or an M&C authorized distributor.
Please follow all instructions and warnings closely.
The product described in this instruction manual has been built and tested in our produc-
tion facility. All analyzers are packed to be shipped safely. To ensure the safe operation and
to maintain the safe condition, all instructions and regulations stated in this manual need
to be followed.
This instruction manual includes all information regarding proper transportation, storage,

2.3 Warning signs and definitions
DANGER DANGER indicates a hazardous situation which, if not avoided, will
result in death or serious injury.
WARNING WARNING indicates a hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION CAUTION indicates a hazardous situation which, if not avoided, could
result in minor or moderate injury.
Beispiel-Einsatzgebiete
Die M&C Gasentnahmesonde SP-180 wird bei der kontinuierlichen Gasentnahme für
analytische Messungen eingesetzt und ist für folgende Bedignungen optimiert:
Staubbeladungen bis 1g/m³
Betriebsdruck bis max. 6 bar abs.
Temperaturen bis max. 600 °C
hohe Gasfeuchte
Dabei entsteht durch die kompakte Bauform nur ein geringer Platzbedarf. Außerdem
kann die Gasentnahmesonde mit neuartiger Schutzhaube zur Montage im Freien ver-
wendet werden.
Beispiel- Wirkungsweise
Auf das Entnahmerohr montiert erfolgt in der SP-180 zunächst eine Feinstaubfiltration
unmittelbar am Entnahmepunkt. Zusätzlich sorgt die integrierte Beheizung für eine
Taupunktüberwachung.
Zur Anbindung einer (beheizten) Abgangsleitung in Richtung der Analyseinstrumentie-
rung besitzt die SP-180 geeignete mechanische und thermisch isolierte Aufnahmen.
Beispiel- Vorteile bei M&C
Die Konstruktion der Sonden ist auf einfache Montage, sicheren Betrieb und problem-
lose Wartung ausgerichtet. Folgende Vorteile stehen dabei im Mittelpunkt:
Gasentnahme bei staubbeladenen Prozessen
geringes Volumen, schnelle Ansprechzeit
einfacher Filterelementwechsel ohne Werkzeug und ohne Demontage der
Entnahmeleitung
einfaches Reinigen des Filterraumes
Reinigen des Entnahmerohres ohne Demontage der Sonde
selbstregulierende elektrische Beheizung mit Untertemperatur-Alarmkontakt
und Entnahmerohre bzw. Vorfilter optional
Standardmäßig mit Kalibriergasanschluss
Bei der M&C-Entnahmesonde SP-180 erfolgt bereits unmittelbar am Entnahmepunkt
eine Feinstaubfiltration. Hierdurch wird ein Teil der notwendigen Wartung eines Sys-
tems auf einen Punkt konzentriert. Diese Filtertechnologie hat den großen Vorteil, dass
Staubgemische aus Grob- wie Feinststäuben besser zurück gehalten werden, verbun-
den mit geringstem Wartungsaufwand.
Zusätzlich wird der Einsatz aller M&C-Filterelemente (Werkstoffe, Filterfeinheiten) mög-
lich. Die neuartige Silikonisolierung ermöglicht zudem eine optimale thermische
Isolierung.
Weitere Hinweise zu interessanten Besonderheiten finden Sie in unserem
Produktdatenblatt.

4 Product overview
The PMA1000/PMA1000L oxygen analyzer is specially designed for continuous measure-
ment of oxygen concentration in gases. With a dead space of only 2 ml (0.07 fl oz) inside
the paramagnetic measuring cell, the response time of the oxygen analyzer is very fast.
The PMA1000/PMA1000L can be used for many applications with the exception of hazard-
ous areas. The oxygen analyzer is ideal for combustion control, process optimisation, iner-
tisation, fermentation processes, environmental protection and for laboratory
measurements.
The PMA1000/PMA1000L has an innovative menu-driven interface. The modular design
gives us the flexibility to quickly adapt to various applications. The oxygen analyzer is us-
er-programmable and easily programmed through the multilevel interface, which pro-
vides convenient access for changing display and menus.
The analyzer housing of the PMA1000/PMA1000L is a 19” enclosure with FKM (Viton®) flex-
ible tubing. The oxygen analyzer has a universal power supply, a seven inch colour touch
screen display and a heated paramagnetic measuring cell (PMC) with sensors and I/O-elec-
tronics. There are also analyzer control features such as a pressure transducer to compen-
sate the process pressure, temperature sensors and flow rate indicators. The
PMA1000/PMA1000L provides an output signal of 0 - 20 mA / 4 -20 mA which is propor-
tional to the measured oxygen concentration. In addition there are also status, alarm and
switching outputs available.
With the available switching outputs, the oxygen analyzer provides two user-programma-
ble operating parameters to monitor the measurement.
A special feature of the PMA1000/PMA1000L is the integrated data logger functionality
which displays the temporal resolution and the long-term data recording of measurement,
warning and alarm signals. The PMA1000/PMA1000L provides excellent calibration ease of
use for zero-point (off-set) and span adjustment.
There are currently two oxygen analyzer models available: PMA1000 and PMA1000L. The
functionality of the L-model includes manual calibration. The PMA1000 features an auto-
mated calibration tool (AutoCal).

5 Measuring principle of the analyzer
5.1 Principle of measurement
All gases are diamagnetic but just a few gases have a paramagnetic behavior. Oxygen is a
paramagnetic gas, which means that oxygen molecules are attracted into a strong mag-
netic field. This paramagnetic susceptibility distinguishes oxygen from most other gases.
The M&C PMA gas is working according to the magneto-mechanical principle: The PMC
uses this paramagnetic characteristic to measure the concentration of oxygen in a gas
mixture.

The PMC used in this oxygen analyzer represents the so called ‘dumbbell’-type. It consists
of two nitrogen-filled spheres suspended on a fine platinum wire in an inhomogeneous
magnetic field. Around the dumbbell is a single turn of platinum wire which is connected
to the rest of the electronics through the platinum suspension. Before the measurement,
the spheres are kept in balance in the inhomogeneous magnetic field. When the gas mix-
ture with the oxygen concentration flows through the paramagnetic cell, the dumbbell
starts moving.

The oxygen molecules are pulled towards the stronger magnetic field zone, and the nitro-
gen-spheres are rotating out of the zone. The mirror, which is secured between the spheres
at the center of the suspension wire, rotates with the dumbbell. Through the twist of the
platinum wire, the mirror reflects light from a light source to a set of photo cells. When the
dumbbell rotates out of the magnetic field, and the suspension wire is twisted, an oppos-
ing current is generated by the electronics to untwist the suspension wire to its origi-
nal-state. This compensating current is proportional to the O2concentration.
