Selection requirements of acceleration sensor:
The sensitivity
The sensitivity of sensor is one of the most basic index of sensor.
Scale range
The measurement range of acceleration value sensor refers to the maximum measurement value that the sensor can measure within a certain nonlinear error range.
Frequency range of measurement
The frequency measurement range of the sensor refers to the frequency range that the sensor can measure within the specified frequency response amplitude error (±5%, ±10%, ±3dB).
The internal structure
The internal structure refers to the way and installation form of the sensitive material crystal plate to feel the vibration.  There are two kinds of compression and shear, and the common ones are central compression, plane shear, triangle shear and ring shear.
Built-in circuit

The built-in concept is to put the charge/voltage conversion amplifier circuit in the accelerometer, become a voltage output function of the sensor element.
