METHOD FOR DETERMINING A POSITION OF A PISTON IN A PISTON PRESSURE ACCUMULATOR BY RESISTANCE MEASUREMENT AND SUITABLY DESIGNED PISTON PRESSURE ACCUMULATOR |
摘要 |
The invention relates to a method for determining a position of a piston (5) in a piston pressure accumulator (1) and a correspondingly designed piston pressure accumulator (1). A housing (3) accommodates a displaceable piston (5). An electrode arrangement (15) having a plurality of 4-point measurement electrode pairs (17) is provided on the electrically conductive housing (3) and is designed to determine a position of the piston (5) inside the housing (3) by measuring a distribution of an electrical resistance or potential between inner electrodes (21) when a current is applied to outer electrodes (19), depending on a position along the housing (3). The position of the piston determined from the measurement of the potential distribution can be used to determine or check a charge state of the piston pressure accumulator (1). |
