Isonic 2005 instruments are now in use for sub-sea inspection.
To perform sub-sea ultrasonic inspection instrument is placed into underwater ROV (Remotely Operated Vehicle) equipped with terminals for connection of probes, scanners and encoders. Earlier they were old fashioned PC aided instruments inside ROV in use, whicjh were controlled by an operator from the surface boat using RS232 mouse adn keyboard. Operators observed relatively low quality analogue image of the instrument screen , transmitted from video camera additionally installed inside ROV to AV monitor on the surface. Beside low-resolution analogue screen image such old fashioned configurations suffered from inability of having digital data on the surface in real time.
Thanks to Windows XP running in our Isonic 2005 instrument todays embodiment is much more advanced: Isonic 2005 instrument is placed inside ROV; it's probe and encoder connectors are cabled to the appropriate terminals while LAN communicateswith operators laptop on the surface boat. The Operatorobserves the same image as on the instrument screen and fully controls the instrument from his laptop keyboard and mouse enjoying the ability of real time transmission of all digital data from sub- sea inspection.
