, linear
Indication
analogue meter with a scale of 0-30 and 0-100% for each selected
range
analogue meter with a scale of 0-30 and 0-100% for each selected
range, digital meter, 3 1/2 digit 9 mm high
for 0-100%O
2
reading, selectivity 0,1vol.% O
2
Output signal
0-1V DC non-isolated, load > 100 KΩ, for the range of 100 vol.%, and
0-20mA or 4-20mA* for the chosen range, non-isolated, max. load
300Ω
Response time for 90% FSD
< 3 seconds at 60 Nl/hr air
Accuracy after calibration
deviation: analogue = ± 1% of span / digital = ± 0,1 vol.% O
2
Reproducibility deviation
analogue = < 1% of span / digital = ± 0,1 vol.% O2
Influence of ambient temperature
no influence up to 45 °C
Influence of barometric pressure
The oxygen reading varies in direct proportion to changes of the ba-
rometric pressure.
Influence of sample gas flow
variation in gas flow between 0-60 Nl/hr air will cause a difference of
< 0,1 vol.% O
