Kondensator und dessen Anwendung

摘要

A capacitor is described, the capacity of which varies with pressure applied thereto. The capacitor may have sheet metal electrodes separated by natural rubber layers, one at least of the electrodes being perforated so that when pressure is applied to the capacitor the rubber can deform and the electrodes can move closer together. The capacitor may be connected in a bridge circuit which then gives an output dependent on the pressure applied. The capacitor is useful in measuring wheel and axle loads.
