The piezoelectric charge constant, d, is the mechanical strain experienced by a piezoelectric element per unit of electrical energy applied, or, alternatively, is the electrical energy generated by the element per unit of mechanical stress applied. Defects in a ceramic, due to incorrect composition, processing inconsistencies, or other problems, are reflected by a low d33 value. Consequently, a fast, easy means of determining d33 is invaluable for ensuring quality and consistency among piezoelectric ceramic components.
We offer one reliable, easy-to-use testing apparatus: a d33 meter.
Our wide-range d33 tester is capable of measuring d33 values from 1 – 200 pC/N or 10 – 2000 pC/N, at high resolution, with a high degree of reliability. The wide-range d33 tester accommodates elements of varied size and shape, and displays readouts directly. No additional equipment is needed to operate the wide-range unit, either for obtaining d33 values or polarity. Power requirements: 110/220 VAC / 50/60 Hz.
This d33 meter offers a fast, easy, reliable way to ensure the quality of incoming components and/or optimize and monitor production processes.
