ECT System for Cylinder Block

ect throughThis eddy current testing system automatically detects a crack on bore part of aluminum cylinder block head, and If a harmful crack is detected, NG paint marking is done on the designated position of the cylinder block.








  • Detecting probe does not contact with workpiece, therefore does not wear
  • All directional flaw inspection can be done by one probe
  • Paint shot NG marking on the pipe (Option)
  • In-line automatic ECT system to fit existing production line can be designed
