ISS-1500SQ is an automatic system designed for the inspection of mechanical components in immersion. The maximum work volume is of 1500x1500x400 mm. The machinery is composed by a tank containing the coupling liquid necessary for the scan process. The hydraulic filtering and UV sterilizing system works to maintain the tank water clean. The inspection test is done thanks to the movement of six axes controlled by PLC which move the probe inside the scan volume. The test object is fixed on a rotating table inside of the tank. A pendant (HMI) is present for the use of the machine. The touch panel is used to send the commands for the functions of the PLC in manual mode and for maintenance procedures. Conformity according to the EMC norms and standards.
