Abstract
The present invention relates to a capacitive sensor comprising two concentric capacitors having a common electrode, namely a high tension capacitor and an auxiliary capacitor, the sensor including two screens separating the two electrodes of the high tension capacitor, and these two screens leaving a gap between each other of constant size. The invention is applicable to metalclad stations.
