Multiscan independent multi-channel ultrasonic detection board adopts modular unit design, which can integrate multiple modules to form a larger multi-channel system according to user needs, such as 4 * N (n≤ 8) ultrasonic inspection system for channels. The board combination is flexible and efficient, and various modules support multiple trigger modes and Cascade synchronization between devices. Each channel data sampling is parallel sampling, each channel PRF up to 1okhz, high-speed automatic detection without pressure. The board provides a complete SDK development package, which can be used for secondary development according to the application characteristics of different industries, and is suitable for automatic production lines in metallurgy, steel, railway, machinery and other industries; customized solutions can also be created according to user needs to achieve a full chain of services from design to installation and commissioning. At the same time, the Multiscan board provides a set of universal software to facilitate users to conduct basic research experiments. The board is reliable and easy to maintain. All kinds of communication interfaces adopt universal design, which can better match all kinds of automatic production lines and provide guarantee for the quality control of industrial automation products.
