Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The optoelectronic measuring system for definition of piezoelectric cell complex gain coefficient Voronov A.S., Pronin S.P. A method to measure piezoelectric cell’s complex gain coefficient is suggested in this article. The method is implemented by a complex harmonious signal effecting piezoelectric cell. The signal consists of a sum of several harmonics with the subsequent calculation of piezoelectric cell complex gain coefficient. The piezoelectric cell output signal is traced by optoelectronic trans-ducer operating by triangulation scheme. Контактный телефон (3852) 36-75-93. E-mail: iit-altgtu@mail.ru
