Abstract
A device for measuring the amount of oxygen in combustion gas including succesively, a channel bordered by two plates between which exists a magnetic field, a central electrode divided in two, longitudinally, a gas discharge path, and finally a mechanism for measuring the current or ionization potential in each of the paths. This device is, accordingly, applicable to the automobile industry and automation and regulation of the operation of boilers of all kinds.
Claims5
A device for measuring the oxygen content in a flow of combustion gases, comprising:
- deflection means in the path of said flow of combustion gases for producing a magnetic field in said flow, whereby oxygen in said flow is at least partially deflected by said magnetic field towards an oxygen rich concentration portion of said flow;
- and
- means for measuring ionization potential of gases in said flow path at a point downstream from said deflection means in the direction of said flow, said means for measuring including means for separately measuring the ionization potential of gases in said oxygen concentration portion of said flow.
