Abstract
Simultaneous neutralization and monitoring of charge on a moving dielectric material is achieved with ionizing devices that supply ions in proximity to the material to thereby substantially neutralize charge on the material, and with circuitry that senses the ion currents flowing from the ionizing devices to the material. A controller can be utilized to control the ionizing devices and/or calculate various parameters (such as charge densities on the web, efficiency, etc.) based on the sensed ion currents.
