Capacitive Tomographic sensor with build in electrodes

The invention discloses a capacitive tomographic sensor with build-in electrodes. The capacitive tomographic sensor is barrel-shaped, and comprises the electrodes in array distribution, an electrode insulating sleeve, a flange outer tube, an insulated tube and a signal transmission line successively from inside to outside. The electrodes in array distribution include N electrode slices in the samesize, each electrode slice is composed of a measuring end and a fixing end, and N represents an integer from 8 to 16. The electrodes are connected with a capacitive tomographic signal collection system via the transmission line, and the collected capacitive data is transmitted to the capacitive tomographic signal collection system via the transmission line, and then transmitted to an imaging computer from the capacitive tomographic signal collection system to complete image rebuilding.
