The piezoelectric charge constant, d, is the charge generated by a piezo element per unit of mechanical stress applied. Typical units are pC/N (picocoulombs/Netwon). The d33 value (d constant in the 33 direction) is a great quick way to determine whether a piezo element is polarized, verify the polarity is correct, and check the magnitude of the d33 value for incoming inspections ensuring quality and consistency among piezoelectric ceramic components.
APC offers a reliable, easy-to-use testing apparatus: the APC Wide Range d33 Meter - Now with CE certification ensuring conformity with European heath, safety, and environmental standards!
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 or mathematical conversions are necessary 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.
