An eddy current acquisition system integrates traditional elements of a nuclear steam generator tubing inspection into a single modular system comprising three subsystems: the take-up reel subsystem, the acquisition instrument, which is located in the hub of the take-up reel, and the pusher head subsystem. All of the control electronics are respectively enclosed in bases of the pusher head and the take-up reel subsystems in water-resistant and dust proof enclosures. Simplified setup is achieved by employing a single communication bus linking an identification (“ID”) chip in each component to a host computer. The ID chip stores and reports product part numbers, descriptions and serial numbers and revision or upgrade status and may also store statistical information such as device duty cycles, performance statistics, repair history, and the like. It also enables auto-fill of product information into firmware of the acquisition instrument, including probe pusher ID, take-up reel module ID, eddy current instrument ID, probe product ID and their serial numbers. It also provides automated inventory management by updating the probe inventory database based when probes are attached and detached from the system. Also implemented in the acquisition instrument module is a real-time landmark detection firmware system.
