Piezoelectric Coefficient (d33) Marine India : YE2730A

The system works by clamping the sample, and subjecting it to a low frequency force. Processing of the electrical signals from the sample, and comparison with a built-in reference, enables the system to give a direct reading of d33 – one of the most useful parameters in evaluating the material. This is a material coefficient representing charge per unit force in the direction of polarisation.
