PiezoClamping® - Prestress and charge meter for piezoceramics

For the assembly of ultrasonic transducers and converters with optimal prestress.

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.

PiezoClamping® overview (video).

PiezoClamping® is easy to use, accurate and immune to the variations undermining traditional methods of prestress control by torque and charge measurement using a voltmeter.

Simply connect the PiezoClamping, entry the ceramics’ parameters and tighten the transducers’ bolt until the target prestress is reached. The tightening can be applied slowly and with pauses.
