YA19T acceleration sensor, access should be vibration test 24-bit data acquisition instrument can be, through the software can test the vibration frequency.
Acceleration sensor commonly used charge type and icp type two kinds, charge type but also add charge amplifier is more troublesome, are generally used ICP type acceleration sensor.
Piezoelectric acceleration sensor, also known as piezoelectric accelerometer. It also belongs to the inertial sensor. It is the use of certain substances such as quartz crystal piezoelectric effect, in the accelerometer is vibrated, the mass of the block added to the piezoelectric element of the force also changes. When the measured vibration frequency is much lower than the intrinsic frequency of the accelerometer, the change in force is proportional to the measured acceleration.
