Estimating the characteristics of piezoelectric transducers
Source abstract
Abstract
A method for estimating the sensitivity of piezoelectric transducers (PETs) is proposed. It is based on normalizing the amplitude of the PET-exciting voltage and calculating the sensitivity with respect to a conventional unit level. The results obtained from measuring PETs produced by well-known foreign manufacturers and at our factory are presented. Attention is also given to measuring the duration of echo signals. The described technique for evaluating the characteristics of echo signals can also be applied to contact angle PETs. The results obtained and proposals put forward in this study can be considered when correcting the Russian Standard for measuring the PET characteristics.
