OptimAE is the world’s only all fiber-optic Acoustic Emission (AE) sensing system, capable of measuring in extreme environments such as high-voltage areas, ATEX zones, and areas with high EMI or liquids. This system overcomes the limitations of classic electrical transducers, extending the benefits of Acoustic Emission to new industries. The system features up to 32 optical channels, a sampling speed of 1 MS/s, and true simultaneous signal acquisition. It is suitable for applications like Structural Health Monitoring, Condition Monitoring, and Measurements in ATEX, extreme low/high temperatures, and radiation (EMI/nuclear) environments.
