Data acquisition system acquires and stores the data. USB Data AcQuisition (DAQ) system provides the choice and flexibility for creating solutions that evolve and expand as per the changing measurement needs. Anyone can quickly and easily acquire measure and analyze data from electrical, mechanical and physical phenomena. In this paper, Acoustic Emission (AE) sensor is used to acquire the data of physical phenomenon (like pencil lead break or crack in beam or leakage in pipeline), which is very small (in mV). This has been further transformed approximately into the higher range (in volts) by using a preamplifier of suitable gain.
