  • Method and apparatus for signalling concentration of air conveyed ionizable foreign matter
    Patent number: 4090308
    Abstract: A method and apparatus by which the degree of concentration of ionizable foreign matter conveyed by an entraining air flow is detected and signalled and in which at least a portion of an air flow and matter conveyed thereby is passed through an ionization detector spark gap while a continuous arcing electrical discharge is maintained across the gap. The electrical conductivity of the discharge is monitored, so that fluctuations in the concentration of conveyed matter are indicated by fluctuations in the monitored discharge conductivity.
