Device for determining the concentration of substances having paramagnetic properties

摘要

A device for the determination of the concentration of substances with paramagnetic properties, particularly oxygen, in substance mixtures comprises a cell assembly and devices to produce a magnetic field as well as to measure changes in the magnetic induction. Great mechanical accuracy and stability in the measuring of a change in the magnetic induction uninfluenced by external disturbing fields or by mechanical changes due to external temperature fluctuations or vibrations with a coil assembly for producing a magnetic field and for measuring the induction signal comprising self-contained coil carriers, which, surrounding a cell assembly and are arranged respectively at a distance from the axis of rotation of the cell assembly.
