AMSY-6

Vallen AMSY-6 is our fully digital multi-channel AE-measurement system. It consists of parallel measurement channels and the system front end software which runs  on an external PC. A measurement channel consists of an AE-sensor, preamplifier and one channel of an ASIP-2 (dual channel acoustic signal processor). Each channel combines an analogue measurement section and a digital signal processing unit. AE-features, such as time of the first threshold crossing (arrival time), risetime, duration, peak amplitude, energy and counts, are extracted by the ASIP-2. In parallel to the feature extraction, the complete waveform can be recorded to an optional transient recorder module.

The AMSY-6 provides 4 types of measurement data:

  • hit data: data that is generated when the AE-signal exceeds the threshold
  • status data: data that is generated in regular time intervals
  • parametric data: data of external parametric sensors which are measured at regular time intervals. Parametric data is stored with every hit and at user specified time intervals.
  • waveform data: sampled AE-sensor signal.

The system front-end software runs on a PC and controls data acquisition, storage of data and is capable of analyzing data online as well as offline.
