The function of the delay line is to separate the piezoelectric transducer from the fluid surface to protect the fragile piezoelectric material from harsh environment, while providing a suitable acoustic path length. The piezoelectric transducer is the active element of the sensor and generates the ul

Acoustic impedance of piezoelectric ceramics is 2.6 0.7kg/m 2s, while that of air is 4.3 0.2kg/m s. This difference of 5 powers causes large loss on the vibra-tion radiating surface of the piezoelectric ceram-ics. Matching the acoustic impedances with air is performed by bonding a special material to the piezoelectric ceram-

The mathematical theory of random vibration is essential to the realistic modeling of structural dynamic systems. This article summarizes the work of some key contributors to the theory of random vibration from

PRÜFTECHNIK AG Vibration Handbook 5 Introduction to vibration measurement The fundamental physical source of this vibration and of the recorded signal could be thought of, for example, as follows: The vibration velocity v is the change in displacement x over a period of time. Its waveform is shifted by 90 from the position

The dynamic vibration tests on structures are generally subdivided into two groups: (a) forced vibration test and (b) ambient vibration test. In the forced vibration test, the structure is usually excited by artificial means. The excita
