EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A 21Sample gas inlet conditions under atmospheric conditionsSample gas compositionThe standard version of the gas analyzer is suitable for measuringnon-flammable and flammable gases under atmospheric conditions, whichcan occasionally form a potentially explosive atmosphere.The oxygen content of the sample gas mixture may be max. 21 % vol. as peratmospheric conditions.If the sample gas only consists of a mixture of oxygen and flammable gasesand vapors, it may be not potentially explosive under any circumstances.This can normally be achieved if the oxygen content is safely limited to max.2 % vol.Flammable gases which are potentially explosive under the conditions ap-plicable for the analysis, even without the presence of oxygen, may only becontained in the mixture to be analyzed in non-safety-critical concentra-tions.The gas analyzer may not be used for measuring gases that attack the mate-rials in contact with the sample medium (e.g. gases containing chlorine).Sample gas inlet and outlet conditionsTemperatureThe sample gas dew point must be at least 5 °C lower than the lowest am-bient temperature in the overall sample gas feed path. Otherwise, a samplegas cooler or condensate trap is required. Fluctuations in water vapor con-tent cause volume errors.Inlet pressureAbsolute pressure max. 1100 hPa and gauge pressure max. 100 hPaFlow rateUras26 20 to 100 l/hMagnos206 30 to 90 l/hMagnos28 30 to 90 l/hCaldos25 max. 100 l/hCaldos27 max. 100 l/hPressure drop at the flame barriersApprox. 40 hPa at a flow rate of 50 l/hOutlet pressureThe outlet pressure must be the same as the atmospheric pressure.
