There are several characteristics of vibration sensors, following the first to tell you about the sensitivity characteristic vibration sensor.
Sensitivity is the most important characteristic of the acceleration sensor. Theoretically the sensitivity of the acceleration sensor as high as possible. However, the higher the sensitivity, the thicker laminated piezoelectric element, resulting in decrease in the resonant frequency of the sensor itself, affect the measurement frequency range. And high sensitivity piezoelectric accelerometer large mass itself is not conducive to measuring light small specimen. Modern measurement system can accept due to the low vibration level signal, and thus the sensitivity is no longer a factor in everything. Sensitivity piezoelectric accelerometer with a charge voltage of two. For ICP sensors are voltage sensitivity.
