Abstract
A device for measuring the concentrations of paramagnetic gases in a gas sample has at least one modulatable magnetic flux source, which has an air gap, to which a gas sample can be fed. A controllable power source, for generating current and voltage signals, is coupled with the modulatable magnetic flux source in order to generate a modulatable magnetic flux within the air gap. Two measuring points are arranged at least partly within the air gap. Each measuring point has an electrically controllable heating device and a heat conduction-measuring unit or resistive measuring device. Each measuring point is coupled with a variable power source to heat the heating device to a working temperature. Each measuring point is coupled with a measuring circuit to measure heat conduction measured signals generated by the heat conduction-measuring unit, from which the concentrations of paramagnetic gases, which are contained in the gas sample, can be derived.
