This paper presents the development of a digital measuring system for long range displacement and velocity based on the combination of PAV-Ⅱ mode transducer and microcomputer. The measuring system, which is suitable to be applied in the field of mechanical automatic machining processes, can be utilized to measure the displacement in the measurement range of 300 millimeter and the velocity below 15m/s of object moving in a straight line. Practical results showed that the design of the system is reasonable and the measuring performance of the system is satisfactory.
