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 shortand
TM -Thru actua-tors), but their high resonant
frequencies make them espe-cially suitable for dynamicoperation with light loads. 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 tomulti-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 avoltage is applied betweentheir inner and outer elec-trodes. Multi-electrode tubesare available to provide XYZ
motion for use in manipulation
and scanning
microscopy
applications. 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 with
diameters as small as 0.8 mm
(inner-diameter) and toler-
ances as tight as 0.025 mm.All manufacturing processes atPI Ceramic are set up for flexi-
bility. Should our standard
actuators 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 smallquantities. Some of our cus-tom capabilities are listed
below:
Micropositioning Scanning microscopy(STM, AFM, etc.) Fiber stretching / modulation of optical path
length Micro pumps / ink-jet
printing Micromanipulators Ultrasonic and sonar applications
