The advanced sensor applied to the dust-charged detection

Abstract

In this paper, a detection sensor is designed. The mathematics and simulation models based on the charge induction mechanism are built. The characteristics of the sensor are developed by using the finite-element method. A method combined by GA (genetic algorithm) and ANSYS is introduced to analyses the optimal sensitive response. The performance has been evaluated. And the device with three probe scales in series illustrates that the dimension of the device is the most sensitivity issue. At same time, a new measurement system based on the differential principles with three probe device is proposed.
