ASCO-DAQ2 is an easy to operate and versatile, single-channel Acoustic Emission (AE) system well suited for many applications such as process monitoring measuring burst and / or continuous AE. ASCO-DAQ2 is a data acquisition module in a rugged box which houses the well proven Vallen AE Signal Conditioner (ASCO-P). Connected to a PC using the standard USB 2.x interface the 4-channel data acquisition module samples APK (Acoustic Peak Amplitude), ASL (timely average of the logarithmized AE signal), external parameters, such as stress, strain, pressure and temperature at a programmable sampling rate and stores the data to a file. ASCO-DAQ2 comes with ready-to-use powerful AscoDaq software package for data acquisition and analysis including automated monitoring and alarm modes.
