THE PIEZOELECTRIC ACCELEROMETER (VIBRATION SENSOR) (Compression Type)

Accelerometers for the measurement of acceleration, shock or vibration come in many types using different principles of operation.




Inside a piezoelectric version, the sensing element is a crystal which has the property of emitting a charge when subjected to a compressive force. In the accelerometer, this crystal is bonded to a mass such that when the accelerometer is subjected to a 'g'
