Analytical Evaluation of Operational Characteristics of a Mid-Plate Adjustable Capacitive Trans

Abstract

In this work, the functional principles of capacitive transducer is revealed with attention on the transduction effect of the device using two parallel plates at both ends. A movable plate at the middle of the device is incorporated by which the electrostatic field within the two extreme plates is adjusted to determine the operational consequence of the mid-plate movement. The two existing voltages due to the two end plates and the moving plate are deduced in relation to the existing parameters of the device. A graphical results are obtained and properly evaluated in attempt to ascertain the basic characteristics under which the operational capability of the three – plate capacitive transduction can be improved for adequate operational result of the equipment.
