Stresstech Group’s main products are Barkhausen Noise analyzers and sensors, custom inspection stands, X-ray Diffraction analyzers and inspection stands. Several different applications use Barkhausen Noise to study magnetic properties and thus the presence or absence of material defects and residual stress levels in various components like gears, bearings, camshafts, crankshafts, universal joints, piston pins, etc.
Magnetoelastic instrumentation (Barkhausen Noise, BN) for testing of residual stresses and for quality control of grinding, heat treating, shot peening, machining, forming etc. includes main testing instrument depending on the main use (Rollscan, Stresscan, μScan) Barkhausen Noise sensor developed for the component to be tested optional component handling equipment (stand) and software for data acquisition.
Stresstech Oy (1984) in Finland, American Stress Technologies, Inc. (AST)(1983) in USA and Stresstech GmbH (1999) in Germany form the Stresstech Group. Being in close contact with each other and with over 20 years of experience of quality control. Stresstech Group’s main products are Barkhausen Noise analyzers and sensors, custom inspection stands, X-ray Diffraction analyzers and inspection stands. Several different applications use Barkhausen Noise to study magnetic properties and thus the presence or absence of material defects and residual stress levels in various components like gears, bearings, camshafts, crankshafts, universal joints, piston pins, etc. X-ray analyzers use X-ray diffraction to measure residual stresses and retained austenite contents. Stresstech Group provides also custom inspection stands for shop floor quality control.
