INTRODUCTION

8.1

SERIAL NUMBER

The type plate with the serial number is fixed on the left side of the analyzer's housing.
Please indicate always this serial number in case of questions or when purchasing spare parts.
8.2

POWER SUPPLY

The internal power supply of the oxygen analyzer PMA50 EX is 115 V or 230 V AC, 40 - 60 Hz. Detailed infor-
mation can be found on the type plates. Variations of the power supply of -15 % to +10 % do not effect the
function of the analyzer.

APPLICATION

The Oxygen Analyzer PMA 50 EX is suitable for the continuous measurement of oxygen in particle-free and
dry sample gases with a maximum dew point of 5 °C [41 °F].
The features of the analyzer are safe operation, accuracy and low maintenance.
The measurement is based on the physical principle of the paramagnetic oxygen measuring cell and is one
of the most exact quantitative methods of oxygen determination within the range of 0-100 vol% oxygen.
There is a direct flow against the measuring cell which has got a low volume of only 2 ml (small stagnant
volume). Further characteristics are robustness, extremely small drift, fast response time (T
negligible cross sensitivities to other sample gas components.
Fluctuations of the flow rate in a range from 0 Nl/h to 60 Nl/h air cause a change of the oxygen reading which
is smaller than 0.2 vol% O
Measurements in flue gas and in inerting plants are among many other measurement tasks which are typical
applications for the PMA 50 EX.
