Abstract

In this paper, we designed the novel capacitive sensor and system for measuring the position of the piston in hydraulic cylinder. The magnetic or LVDT sensors have been widely used to measure the position of the piston because of its high accuracy, but these types of sensor are very expensive and have difficulty in use because of its complexity. To overcome these disadvantages, we studied the optimized non-contact capacitive sensor and designed detecting system for accurate measuring the location of piston in hydraulic cylinder. The proposed capacitive sensor and detecting system have the possibility of practical use for hydraulic cylinder through experiments.
