ASCO-P
an analog AE-signal conditioner
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 enabling 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.
