An external fine filter must always be used at the gas inlet of the analyser. Depending
on the composition of the sample gas, it may be necessary to use a sample conditioning
system. Without precautions, the analyser is only suitable for measuring of non-hazardous
gases or gasmixtures in non-hazardous areas.
Version PMA 100 microprocessor based oxygen analyser in 19"-housing
Part No. 03A3000 : PMA 100 power supply 230V 50Hz, 4-20mA; 03A3000a = 115V 60Hz
Measuring ranges 4 linear measuring ranges free selectable, lowest span 1%,
basis selection* 0-1, 0-10, 0-25 and 0-100 vol. O2.
manual, automatic or remote range control and range indication is possible
Indication two line 16-sign LCD display, resolution 0,01vol.% O2, continuous O2 indication and call off
Text illustration optional in
English, French or German
O2-transducer temperature, mA-signal, measuring range, time, date, failure-/alarm information,
process pressure
Output signals selection: isolated 0-20, 2-20, 4-20*, 4-20,5mA for the selected range, max. load 500Ù.
interface RS232 type AK-communication protocol - bi-directional, option interface RS485 type
Relay outputs free configurable 4 potential free relay contacts NO, contact rating max. 48VDC, 500mA, 15W
Binary outputs drive of 3 external solenoid
valves for calibration, 3x 24VDC, max. 400mA
Binary inputs free configurable potential free, 4x 12-24VDC, max. 20mA or internal supply voltage 12 VDC
Flow alarm thermo-conductive sensor, mounted downstream O2-measuring cell
Status alarm for min. flow alarm, O2-transducer temperature < 50 °C, central processing unit failure, pressure sensor: LED
indication and potential free contact output, NO, max. 48VDC, 500mA, 15W
and mA-output indication - example 22mA
Alarm contact for exceed/remain measuring range, truncate calibration, external alarm, alternatively oxygen level alarms: LED
indication and potential free contact output, NO, max. 48VDC, 500mA, 15W
Response time for 90% FSD < 3 seconds at 60 Nl/hr air
Accuracy after calibration deviation ± 1% of 2-100% span, ± 2% of 1% span
Reproducibility deviation < 1% of span
Influence of ambient temperature no influence up to 50 °C
Influence of barometric- or
process pressure
no influence within the range of 0,6 up to 1,6bar abs. with integrated pressure compensation
Influence of sample gas flow variation in gas flow between 0-60 Nl/hr air will cause a difference of < 0,1 vol.% O2
Sample gas inlet pressure 0,01 up to 0,6 bar g, (PMA 100 requires positive pressure for adequate flow rate, no pump inside)
Sample gas outlet pressure recommendation: discharge freely into atmosphere; however max. 0,6 to 1,6 bar abs.
Flow rate of sample gas 25-60 Nl/hr air
Temperature of sample gas -10 °C up to +50 °C dry gas
O2-transducer temperature fixed at +55 °C
Ambient temperature -10 °C up to +50 °C
Storage temperature -20 °C up to +60 °C, relative humidity 0-90% RH
