Piezoceramic disk – the heart of the transducer
High-quality piezoceramic transducers at the heart of our ultrasonic transducers
We source our piezoceramic transducers from selected suppliers, preferably locally and with above-average quality standards. Our main supplier PI Ceramic manufactures a material specially specified for us. This is characterized by a high degree of efficiency as well as minimal geometric and electrical tolerances.

We would like to thank them for the decades of trustful cooperation and millions of piezo elements of the highest quality – Made in Germany.
What role does the piezoceramic disk play in the ultrasonic transducer?
In an ultrasonic transducer, the piezoceramic disk plays a central role, as it enables the basic function of the transducer: the conversion of electrical signals into mechanical vibrations and vice versa.
How the piezoceramic disk works:
1. piezoelectric effect
The piezoceramic disk is based on the piezoelectric effect. This means that certain materials, such as piezoceramics, generate electrical charges when mechanically deformed. Conversely, these materials generate mechanical vibrations when exposed to an electric field. We use precisely this effect in our ultrasonic transducer.
2. generation of ultrasonic waves
If an electrical voltage is applied to the piezoceramic disk, it deforms due to the piezoelectric effect. This rapid deformation leads to mechanical vibrations that are emitted as ultrasonic waves into the surrounding medium (e.g. air, water or human tissue).
3. reception of ultrasonic waves
Conversely, the piezoceramic disk can also receive ultrasonic waves. When an ultrasonic wave hits the disk, it deforms mechanically, which generates an electrical voltage in the disk. This voltage is then evaluated as an electrical signal.
Meaning in the ultrasonic transducer:
Signal conversion
The piezoceramic disk is the heart of the ultrasonic transducer, as it enables the direct conversion of electrical signals into ultrasonic waves and vice versa.
Efficiency and frequency control
The thickness and material of the piezoceramic disk determine the frequency of the ultrasonic waves generated, which is decisive for the transducer’s areas of application.
Sensitivity and precision
The quality of the piezoceramic disk influences the sensitivity of the transducer. High-quality piezoceramics can convert very small mechanical changes into electrical signals, which is important for accurate measurements.
Overall, the piezoceramic disk is the core component of an ultrasonic transducer, which makes it possible to generate and receive sound waves with high precision. Without it, the functionality of an ultrasonic transducer would not be possible.
