Langevin Transducers for Ultrasonic Welding

Main Features

• High Mechanical Quality factor and excellent electro-acoustic conversion efficiency, providing high output amplitude.
• Piezoelectric element offer a high speed of vibration. Through bolt-on presstress, mechanical and amplitude have been improved.
• Having steady output amplitude even under markedly changed loads.
• Extended temperature use, ensuring good amplitude linearity. Low resonant impedance ensuring high conversion efficiency. 
• Bolt-on pre-stressed design provides fast and easy installation with high reliability.
