SPRAY DEPOSIT SAMPLING TECHNIQUE TO EVALUATE ELECTROSTATIC AERIAL SPRAY-CHARGING

The electrostatic charging of agricultural chemical sprays applied by aircraft offers theoretical advantages that are urgently needed by the aerial application industry. Research on equipment and methodology for aerial electrostatic spray-charging has resulted in a need for ground-based assessment equipment for evaluation of the electrostatic charging of aerial sprays. The paper reports on an electronic, buffer amplifier circuit that was designed, developed and field tested to evaluate electrostatic charging of aerial sprays. The circuit was designed to detect the passage of an electrostatically-charged aircraft; the falling of charged-particle, spray-cloud plumes; and the spray charge deposited upon a sphere.
