SAEU3H Multi-Channel Acoustic Wave (Acoustic Emission) Testing System

SAEU3H MULTI-CHANNEL AE SYSTEM, SEAU3H AE system supports USB3.0 (standard)

SAEU3H MULTI-CHANNEL AE SYSTEM, SEAU3H AE system supports USB3.0 (standard)

SAEU3H is a multi-channel acoustic wave (acoustic emission) acquisition and processing desktop type AE system. A complete SAEU3H system is composed of a certain number of AE acquisition boards in a chassis, AE sensors, preamplifier, coaxial cables and the SWAE analysis software in the computer.

SAEU3H acoustic emission system uses USB3.0 (or TCI/IP, optical fiber) communication mode to connect to the computer, with a data passing rate of up to 600MB/S. Multiple acoustic emission instruments of the same model (SAEU3H) can be cascaded to form a super large system with more than 100 channels by using the standard HDMI cables.

SAEU3H system has strong data acquisition and data processing capabilities, which is suitable for a vast majority of industrial testing applications, as well as laboratory researches with the strict requirements for data accuracy.


  • High integration and easy to carry;
  • The chassis model, the number of chassis, and the number of AE acquisition cards can be configured according to needs to form a system of multiple channel models. Multiple chassis can be cascaded to form a large-channel acoustic emission system. Each chassis can be used as a separate host and can be expanded to more than 100 channels;
  • Data communication between the acoustic emission instrument host and computer can choose USB3.0 interface, LAN network port, optical fiber and other connection methods;
  • The network port data communication method is optional. The network port communication configuration network switch can form a variety of acoustic emission network structure systems such as local area network, wireless, and remote control;
  • Each AE board is equipped with 1Gb large-capacity DDR memory to ensure that data is not lost when a large number of signals (less than 1Gb/s) are transmitted instantly;
  • Multiple waveform acquisition triggering methods: threshold trigger, time trigger, external trigger, parameter trigger, to meet various acquisition needs;
  • Hardware real-time digital filter function: set pass-through, high-pass, low-pass, band-pass and band-stop filters to any value within the frequency range of 1kHz-2MHz. The continuous signal of each channel is digitally filtered and the waveform is reconstructed. The reconstructed waveform generates acoustic emission parameters;
  • Hardware real-time FFT analysis function: acquisition hardware continuous signal FFT frequency domain waveform and power spectrum parameter output;
  • The preamplifier status is automatically detected to facilitate on-site debugging. At the same time, the preamplifier voltage is adjustable to adapt to preamplifiers of different specifications;
  • Automatic sensor testing (AST): Built-in AST function, the acquisition card can emit acoustic emission signals for testing;
  • Innovative motherboard bus design enables intelligent management of data collected from each acquisition, and can be expanded to other types of boards to achieve long-term monitoring, storage, and long-distance transmission functions;
  • The chassis is made of all-aluminum alloy material, and the entire chassis frame and panel are conductively interconnected and fully shielded to enhance the ability to resist electromagnetic interference;
  • The power supply and heat dissipation are precisely designed according to thermodynamics and aerodynamics to ensure uniform heat dissipation, reliable, stable and long-term operation under the most demanding conditions;
  • High-end standard industrial chassis similar to PXI plug-in functional module structure, with good scalability. Function module cards such as acquisition boards are relatively independent from the chassis, making it easy to maintain and upgrade the equipment;

The panel has multiple sets of indicator lights to display power, USB communication, operation, parameters, waveforms, alarms, external parameters, cascade, etc., making it easy to observe the operating status of the equipment. External trigger, alarm output;
