Capacitance Measurement with a Sigma Delta Converter for 3D Electrical Capacitance Tomography
Abstract
This paper will explore suitability of a newly available capacitance to digital converter for use in a 3D Electrical Capacitance Tomography system. A switch design is presented along with circuitry needed to extend the range of the capacitance to digital converter. Results are then discussed for a 15+ hour drift and noise test.
