The materials used in APC’s standard piezo cylinders are specially formulated for cylinders. APC’s Type I and Type II materials are high density, fine grain, PZT ceramics that exhibit a high dielectric constant, high electromechanical coupling factor, high charge sensitivity, and a high Curie point (See Material Specifications). Clean responses make these ceramic materials ideal for various low-power and high-power piezo devices:
Electrodes are located on the inside surface (ID) and outside surface (OD) of the cylinder. The piezo cylinders (tubes) are poled through the wall thickness with the ID being positive. Please inquire about other poling options.
