abstract = "Non-intrusive pressure measurement has the crucial role to the failure diagnosis and detection of hydraulic system where the conventional measurement instruments fail to make the necessary pressure readings within the sealed pipes. The measurement principle based on ultrasonic method was discussed in this paper. In order to make the processed method be suit for the hydraulic pipes which diameter of the pipes is less than 15mm and improve the measuring accuracy, a time delay estimation method based on cross-correlation theory was proposed. By applying the ultrasonic method and cross-correlation theory, the testing platform of pressure via time delay measurement was designed. The simulation and testing results indicate that the proposed method is feasible for non-intrusive measurement of pressure. It offers a new online pressure measurement method for hydraulic system which diameter of the pipes is less than 15mm.",
