Welcome to the KEMET ND Series Piezoelectric Ceramic Disc Shape Transducers product training module. Piezoelectric ceramics have the property of displacing in response to applied voltage and generating voltage in response to pressure and are used in a wide range of applications, from everyday household appliances to industrial equipment. This module provides the customer with more detail of these features and benefits. The training begins with an explanation of piezoelectric principles and the suitability of KEMET piezoceramic materials for applications. Next, the focus will be on explaining disc products, the ND series using KEMET piezoelectric ceramic materials and how to use them. Finally, since piezoelectric ceramics are essential for the generation and detection of ultrasonic, the designer will conclude the training with some examples of applications that utilize ultrasonic.
