ELECTROSTATIC CHARGE MEASURING DEVICE

摘要

This disclosure relates to field strength meters and particularly to meters for detecting and indicating the strength of an electrostatic field in the vicinity of an aircraft. More particularly, this invention relates to a device that uses the inverse of the Van der Graaf generator principle for charging a series of plates, successively, to the potential of a given area of the outer surface of an aircraft and carrying the charged plates within the metal shell of the aircraft to measure the charge on the plates, which is proportional to the electrostatic charge on the adjacent surface of the aircraft.
