  • Device for detecting the ionization level of a gas mixture controlled by electric arc
    Patent number: 4629992
    Abstract: Ionization of a medium being monitored is caused by an electric arc between a first pair of electrodes, while the conductivity of the medium between two measuring electrodes controls at least one feedback circuit which indicates relative rates of decay of the ions, as a function of variations in the number and mobility of ionized particles in the ambient medium.
