ATG s. r. o Beranovych 65 199 02 Praha 9 - Letnany CZECH REPUBLIC e-mail: atg@atg.cz http: www.atg.cz HORIZONTAL BENCH FOR MAGNETIC PARTCLES INSPECTION Horizontal magnetic particle inspection crack detector UNIMAG 600 AC/AC is designed for detection of surface defects in ferro-magnetic materials. This testbench allows application of different magnetizing techniques: • Circular magnetization due to AC current flow through the tested part • Circular magnetisation of hollow parts due to AC current flow through the central conductor • Longitudinal flux flow magnetizing • Transformer magnetization - electric current induction on a hollow part surface by means of a central laminated Cu/Fe twincore bar • Combined magnetization - simultaneous longitudinal and circular magnetization The use of a laminated twincore bar allows combined magnetization of longitudinal flux flow and current flow. It is advantageous especially for testing of ring shaped parts. The PLC based control system assures preset of testing parameters - like current control, timing of magnetization, spraying time etc.. In the case of a higher differences between measured and preset values (oxidized contacts etc.) the magnetisation is automatically interrupted.
