PARAMAGNETISK ANALYSATOR MED SNABBT GENSVAR, FOR METNING AV SYREINNEHALL I GASER

摘要

The invention relates to paramagnetic analyzer for measurement of oxygen contents of gas mixtures. The analyzer comprises electromagnet in a closed cavity controlled with chopped DC-current, sample and reference gas conduits entering the cavity and magnet core and common exit conduit. Gases are led to magnetic field in the gap between magnet poles through holes (13) and (14) drilled into the magnet core so that pedestals (15 and 16) in the gap guide gas flows to collide to be mixed. The mixed gas flows freely out from the gap to the surrounding cavity space (1).
