Abstract:
Air ionization control apparatus comprising a plurality of emitter lines suspended in the atmosphere above a work space, each line comprising a plurality of ion emitting stations spaced therealong and emitting positive and negative ions into the atmosphere with an elongated electrical conductor averaging bar. insulatedly mounted in the atmoshere among said stations for receiving an induced charge representative of the average level of ionization of the atmosphere. An electrical charge sensing means connected to the averaging bar is employed to provide a signal indicative of the average level of ionization present in the room environment.
