Microminiature Piezoelectric Accelerometer
The microminiature piezoelectric accelerometer features an ultra-small, lightweight design that minimizes mass loading effects on the test object. Its high sensitivity and wide frequency response make it ideal for vibration measurements on compact electronic devices, circuit boards, and precision components. It is widely used in modal testing, structural diagnostics, and high-density measurement layouts where minimal sensor influence is critical.
