Gas sampling and gas conditioning technology 9-3.5.1-ME
Every change of the oxygen concentration produces a lineary proportional change of the co m-
pensation current and can be read directly in % O
2
as oxygen value on the display .
Due to its very small stagnant volume (2 cm
3
) and the direct flow of the M&C measuring cell, an
extremely fast response time (T
90
-time) of 1 second for a high gas flow can be realized.
11 RECEIPT OF GOODS AND STORAGE
The analyser PMA 20 is a completely pre-installed unit.

Please take the analyser and possible special accessories carefully out of the packaging m a-
terial immediately after arrival, and compare the goods with the items listed on the packing list;

Check the goods for any damage caused during delivery and, if necessary, notify your trans-
port insurance company without delay of any damage discovered.
N O T E !
The oxygen analyser PMA 20 must be stored in a wheather - pro-
tected and frost-proof area !
12 INSTALLATION
The PMA 20 is intended for stationary operation. In combination with a gas conditioning accord-
ing to the requirements a long lasting operability and a minimum of maintenance is guaranteed.
C A U T I O N !
The sample gas has to be dust free and dry to prevent a conta-
mination and condensation in the analyser.
Basically always connect a fine filter (e.g. type FP-2T, Part No.
01F1200) upstream.
C A U T I O N !
In case of outdoor operation protect the analyser against sun,
wind and rain.
At the installation location constant climatic ambient conditions
(pressure, temperature) are necessary to prevent a distortion of
the measurement and a condensation in the measuring cell in
case the ambient temperature is falling below the dew point
temperature of the sample gas.
A vibration-free location is ideal for mounting; if this is not
possible, appropriate measures have to be taken. The analyser
must not be installed in direct proximity of heat sources.
The position of operation is not necessarily horizontal.
D A N G E R !
The analyser is allowed to be operated only in non-hazardous
areas and with non-ignitiable gases and gas mixtures.
Mounting is done at the four exterior fixing holes (6mm) with adequate screws. Leave enough
space (approx. 120mm) at the right side of the housing for opening the housing in case of main-
tenance.
