ultrasonic cleaning ring-Φ38×Φ15×5mm
Piezoelectric ceramic rings
ultrasonic rings for cleaning resonator
Piezo ceramics have a wide range of uses. Piezo ceramics are used in the automotive industry in a number of applications such as in knock and oil level sensors or as actuators for precise control of injection processes in engines. Common applications in mechanical engineering include ultrasonic cleaning, ultrasonic welding and active vibration damping. Pickups for musical instruments or burglar alarms are examples for the use of piezo-electric technology in consumer applications.
