ASCO by Vallen Systeme GmbH
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.
The AE-Signal Conditioner ASCO-P is a low cost, single channel, analogue device that helps monitoring growth of defects in real time. The analogue output signals (APK, ASL) can be recorded by a data logger for real time or post analysis. A digital threshold crossing output pulse can be used as a real time trigger for controllers.
ASCO-P converts the AE-sensor signal into a peak signal (APK) and an average signal (ASL). The peak signal is stretched to 0.5 or 51ms eanbling a slow data logging unit to record short peak amplitudes of an AE signal. The basis of the average signal is a logarithmized input signal. Additionally, a digital event output allows for external event counting.
Founded in 1980, Vallen Systeme specializes in the development and manufacturing of instrumentation for Acoustic Emission (AE). The company is dedicated to the support, reliability, and performance of their products.
