SMT2 is an automatic system designed for the inspection of sheets. The machinery is composed by a stainless steel frame with 20 liters tank containing the coupling liquid necessary for the scan process. SMT2 is equipped with n°4 wheels (2 fix + 2 pivot) necessary for moving while scanning. The probes lifting system allows to move without the probe holders being in continuous contact with the surface. The power supply of the system is: 12Vdc + 10A. The scan operations are managed by the operator thanks to the dedicated SW installed on the PC. The UT device is powered by n°2 lithium batteries.
