Immer sonic system is used for inspection and testing of components which are axis symmetric and/or non symmetric components. The system comprises an Immersion Tank with multi-axis drives. All the movements are controlled through the system software, and are reprogrammable as per requirements. The ultrasonic data acquisition consists of A-Scan , B- Scan and C-scan display, which are synchronized to give an accurate information of signal amplitudes, and locations of defects. The advantage of such arrangement is that it is easy to align/normalize transducer to be perpendicular, while in straight down position. The system useslow noise drives, with optical encoder inputs for each axis. The system can also be used with angular positioning motors(like stepper motors with a worm gear box, and power drive). The system incorporates low drives noise by the virtue of its design. The drive motion is rigid and does not deviate from the specified position. A water conditioning unit will be provided for inspection and filtering of water ,through a set of pump, and filter. The quality of water used isde-mineralized water. A continuous loop water chiller is used to maintain water /oil temperature. The system has a set of limit switches for all degree of freedom with software, and hardware limit switches, and a master emergency switch. An additional Proxy switch can be used on the transducer to prevent it from touching the component. The base mounting is done with Anti-vibration mounts.
