We discuss the general theoretical characterization of a Gas-Path debris detection monitoring system based on electrostatic sensors and charge amplifiers. We provide the analytical expression of the time-varying charge induced by the moving debris on the sensor surface, discussing the effects of the amplifier bandwidth on the shape of the output voltage signal. Theoretical results have been validated with experiments.

Abstract
We discuss the general theoretical characterization of a Gas-Path debris detection monitoring system based on electrostatic sensors and charge amplifiers. We provide the analytical expression of the time-varying charge induced by the moving debris on the sensor surface, discussing the effects of the amplifier bandwidth on the shape of the output voltage signal. Theoretical results have been validated with experiments.
