PiezoClamping - Prestress and Charge Meter for Piezoceramics - Brochure

PiezoClamping is a piece of novel equipment to standardizes the prestress on the piezoceramics, preventing damage in converters and Langevin-type power ultrasonic transducers. Unlike torque control, prestress is a well-defined value that depends mainly on the piezoelectric material compressive strength. The ideal prestress is insensitive to the bolt type, thread characteristics and lubrication.
