industrial actuators are notdesigned to withstand large
forces (see PICA-Thru actua-
tors), but their high resonant
frequencies make them espe-
cially suitable for dynamic
operation with light loads.
Selection of PT piezoceramic tubes. Short Leadtime for Standard& Custom Designs Because all piezoelectric mate-rials used in PT tube actuators
are manufactured at PI Ceramic, leadtimes are short
and Standard & Custom Sizes For OEM Applications XYZ-Positioning quality is outstanding. Allstand Sub-Nanometer Resolution ard and custom actuatorsare delivered with perform-
ance test sheets. Large Diameters to 80 mm Wall Thickness as Small as 0.3 mm Amplifiers, Drivers &Controllers PI offers a wide range of con-trol electronics for piezo actua-
tors from low power drivers to
multi-channel, closed-loop,digital controllers. PT-series piezoceramic tubesare used in a wide range of
applications from microdis-pensing to scanning micro-scopy. These monolithic com-
ponents contract laterally (radi-
ally) and longitudinally when a
voltage is applied betweentheir inner and outer elec-trodes. Multi-electrode tubes
are available to provide XYZ
motion for use in manipulationand scanning microscopyapplications. PI also provides ultra-high-linearity, closed-loop scanning stages for SPM and
nanomanipulation. Precision and Flexibility: PI Ceramic’s Strength
Application Examples PT piezo tubes are manufac-tured to the tightest tolerances.
We can provide tubes withdiameters as small as 0.8 mmand tolerances as tight as 0.025
mm.All manufacturing processes atPI Ceramic are set up for flexi-bility. Should our standardactuators not fit your applica-
tion, let us provide you with a
custom design. Our engineers
will work with you to find theoptimum solution at a very
attractive price, even for small
quantities. Some of our cus-
tom capabilities are listedbelow:
Micropositioning Scanning microscopy(STM, AFM, etc.) Fiber stretching / modulation of optical path
length Micro pumps / ink-jet
printing Micromanipulators Ultrasonic and sonar applications
