Abstract

The aim of this paper is to present the mechatronic system for technical diagnostic based on magnetic Barkhausen noise analysis. Intended use of this system is especially residual stress control with crack prediction or subsurface layer microstructure investigation of flat parts of machineries and constructional elements. The basis of Barkhausen noise inspection methods, fields of applications, construction of the investigation apparatus and details of measuring head positioning system were described. Horizontal setting of the head was realized with the step motors. The vertical lifting and lowering is controlled by pneumatic system. Open structure of the system let to use for control and data acquisition the standard PLC controllers.
