WARNING!IMPORTANT!
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 conditio-
ning system.

Output signals 0-10V DC, burden >100 KΩ for range 0-100 % isolated.
0/4-20mA burden 270 Ω for every measuring range, electrically isolated; output voltage max. 15V (ex works).
Switchable max. burden 800 Ω, output voltage max. 30V.
Output current limiting adjustable 20mA-22mA (20,5mA ex works)
Response time for 90% FSD < 5 seconds at 60 Nl/hr air
Accuracy after calibration deviation: analogue signal output = ± 1% of span at range 3 - 100% / digital indicator = ±0,1 vol.% O

= ± 2% of span at range 1%
Reproducibility deviation: analogue signal output = < 1% of span / digital indicator = ±0,1 vol.% O

Influence of ambient temperature no influence up to 50 °C
Influence of barometric pressure The oxygen reading varies in direct proportion to changes of the barometric pressure
# no influence from 0,5-1,5 bar abs. at PMA 50 EEX/P/PD-1-50 with process pressure compensation
Influence of sample gas flow Variation in gas flow between 0-60 Nl/hr air will cause a difference of < 0,2 vol.% O
