Reliable dynamoelectric machine condition monitor

An apparatus for detecting thermoparticulates in a gaseous carrier, said apparatus comprising:

• a gas ionization chamber which includes a source of radiation to effect ionization of the gaseous carrier;
• a first detector means comprising a first electrode, a second electrode, an outer shell, and a voltage applied between said electrodes, said detector is operatively joined to said ionization chamber to receive said ionized gas with thermoparticulates dispersed therein;
• a second detector means comprising a third electrode, a fourth electrode, an outer shell, and an applied voltage between said electrodes, said second detector is operatively joined to said first detector to receive said gaseous carrier with charged thermoparticulates dispersed therein;
• said first detector's voltage is of such a potential to ensure substantial electrodeposition of said gaseous carrier's free ions;
• and
• said second detector's voltage is of such a potential to ensure electrodeposition of said charged thermoparticulates and to produce a current flow through a load connected between said third and fourth electrodes whose magnitude is proportional to the quantity of charged thermoparticulates dispersed within said gaseous carrier.
