Method for Ultrasonic Non-Intrusive Pressure Measurement Based on Cross-Correlation Theory
摘要
Abstract
Non-intrusive pressure measurement play a crucial role in the failure diagnosis and detection of hy-draulic system. The method based on ultrasonic is discussed. In order to improve the measuring accuracy, the time delay estimation method based on cross-correlation theory is proposed. Also the measurement system via ultrasonic technique is designed. The results indicate that the proposed method is feasible for non-intrusive pressure measurement. It offers a new online pressure measurement method for hydraulic system which diameter of the pipes is less than 15 mm关键词
