Abstract
A relatively simple and compact device is disclosed for monitoring ion imbalance at a preselected, or work, area. A collector is utilized that is charged due to ions contiguous thereto, with the charge at the collector being processed, preferably utilizing a charging capacitor and operational amplifier, to provide an output signal indicative of ion imbalance at the preselected area, which output signal is then utilized to produce an indication of ion imbalance at the preselected area and/or to correct the ion output of an ion generator directing ions toward the preselected area. A pair of collectors can be utilized to separately sense positive and negative ions separately generated by an ion generator with the acquired charge on each collector being separately processed, and the indication of ion imbalance can be accomplished utilizing a meter and/or alarm.
