FAQ: I measured some piezoceramic rings, but I cannot understand whether the ceramic is good or bad with respect to internal cracks. Do I have to check the ceramic from both polarities? Mr. F.S.
Curve of a piezoelectric ceramic with internal crack tested by the TRZ® Analyzer.
The results evaluation is graphic / visual and consists in verifying the occurrence of additional small resonances in the piezo element’s impedance curve.
