Abstract
A capacitive measurement device is provided, including: (i) a first electronic system electrically referenced to a guard potential and connectable to capacitive electrodes; (ii) a second electronic system electrically referenced to a ground potential; and (iii) an energizing component connected to the guard and ground potentials, respectively, to impart an AC voltage differential between the potentials. The device also includes an integrated circuit that is referenced to the ground and includes a first installation area in which the first electronic system is implemented, and a second installation area in which the second electronic system is implemented. Also included are systems using the device and uses of the device.
