1. DESCRIPTION The Model YE2730 d33 meter is a special instrument directly to measure piezoelectric constant d33 values of piezoelectric ceramics, polymers, and single crystals. This meter can also measure d33 value in various single crystal materials, such as lithium niobate, quartz, and tourmaline. This meter is capable of measuring d33 value over a very large range, at high resolution, and with a high degree of reliability. The measurement is quickly, and easily made with a minimum of training required. Specimens of a variety of sizes and shapes can easily be accommodated and measured. For example: d33 value of disks, blocks, rings, tubes and semispherical shells can be easily measured and displayed on the Model YE2730 d33 meter. Measuring d33 value is displayed on a 3 1/2 inch digital meter. This instrument is invaluable as a tool for quality assurance of piezoelectric materials, production in-line inspection, or for research applications. 2.
