Background information about piezo cylinders
Custom Designed and Engineered Cylinders
To meet your unique specifications, APCI can manufacture cylinders (tubes) in a wide range of sizes and thicknesses and out of materials other than our standard material (Type II ceramic). To discuss your requirements, simply
contact an APCI representative with your drawing or sketch including: tolerance
values, material, and electrode pattern.
Standard Piezo Cylinders
Constructed from Type II ceramic material (See properties below).
Electrodes on inside surface and outside surface, cylinders
poled through the electrodes. Please inquire about other poling
options.
