Quality Assurance System

Fully ensuring the quality of actuators

In order to exploit the piezoelectric effect of the piezo actuators, the piezo ceramic must be polarized by aligning the electrical dipole moments. Automated tests are conducted using the Quality Assurance System so that the actuator can be polarized and the mechanical strength of the actuators tested. The actuator is impinged with a sinusoidal current in a freely oscillating configuration, i.e. without mechanical preload, and at the same time adjusted to a medium voltage via the voltage channel. Triggering takes place via the Quality Assurance System combined testing and analysis instrument using a hybrid power amplifier. The system ensures consistently high quality, which greatly reduces the probability of a failure in the field.
