Advantages of the piezoelectric transducer: Most sensors have a wide frequency range, usually between 2 Hz and 15,000 Hz. Because of non-contact mechanical energy transfer, vulnerable key components can be packaged without affecting the normal operation. One example is when two components are connected with a defined force, as in the case of riveting.
