Outstanding lifetime thanks to PICMA® piezo actuators
The PICMA® piezo actuators are all-ceramic insulated. This protects them against humidity and failure resulting from an increase in leakage current. PICMA® actuators offer an up to ten times longer lifetime than conventional polymer-insulated actuators. 100 billion cycles without a single failure are proven.
Subnanometer resolution with capacitive sensors
Capacitive sensors measure with subnanometer resolution without contacting. They guarantee excellent linearity of motion, long-term stability, and a bandwidth in the kHz range.
High guiding accuracy due to zero-play flexure guides
Flexure guides are free of maintenance, friction, and wear, and do not require lubrication. Their stiffness allows high load capacity and they are insensitive to shock and vibration. They work in a wide temperature range.
Automatic configuration and fast component exchange
Mechanics and controllers can be combined as required and exchanged quickly. All servo and linearization parameters are stored in the ID chip of the D-sub connector of the mechanics. The autocalibration function of the digital controllers uses this data each time the controller is switched on.
Maximum accuracy due to direct position measuring
Motion is measured directly at the motion platform without any influence from the drive or guide elements. This allows optimum repeatability, outstanding stability, and stiff, fast-responding control.

Tecnologia
Tecnologia PICMA®
Elevata affidabilità e lunga durata attraverso il processo di produzione brevettato per attuatori multistrato.
Sistemi con Guida a Flessione
Le Guide a Flessione realizzate da PI hanno dimostrato i loro punti di forza nei nanoposizionatori. Guidano l'attuatore piezoelettrico e garantiscono un movimento rettilineo senza inclinazione o spostamento laterale.
Controllori Digitali
La tecnologia digitale apre a diverse possibilità di miglioramento delle prestazioni nell'ingegneria di controllo che non sono possibili con la tecnologia analogica convenzionale.
Sensori Capacitivi
I sensori capacitivi sono il sistema metrologico prescelto per le applicazioni più esigenti di nanoposizionamento.
Sistemi Di Posizionamento Piezo a Cinematica Parallela
In un sistema multiasse a cinematica parallela, tutti gli attuatori agiscono direttamente su un'unica piattaforma mobile.
Vuoto
Gestione attenta, locali adeguati: PI non solo ha le attrezzature necessarie per la qualificazione dei materiali, dei componenti e dei prodotti finiti, ma vanta anche molti anni di esperienza per quanto riguarda sistemi di posizionamento in HV e UHV.
