Efficient Barkhausen Meter for routine quality inspections Rollscan 250 is an instrument for controlling the surface quality and testing of near-surface defects in a wide variety of ferritic steel and other ferromagnetic materials. Rollscan 250 easily detects defects related to changes of stresses or microstructure. These defects are commonly due to failed grinding, heat treatment, shot peening, or any other surface treatment process.

Rollscan 350 saves on material and labor expenses Rollscan 350 is a digital Barkhausen noise analyzer. It is designed for surface quality control and testing of near-surface defects such as grinding burns, heat treatment defects, as well as changes in stress and microstructure in a wide variety of ferritic steel and other ferromagnetic materials. Inspection with Rollscan is fast and can easily match the production rates of most manufacturing lines, enabling process control in real-time. As a result, significant quality improvements and savings on material and labor expenses have been realized by companies using the Rollscan system. A large selection of sensor types makes Rollscan systems flexible. Piston pins, gears, bearing rings and rollers, camshafts and crankshafts, and landing gears are just some of the parts that can be successfully tested with Rollscan 350.

X-RAY DIFFRACTION is the conventional and time proven technique for measuring residual stresses. Using the interatomic spacing as the ultimate gage length, the X-ray technique is ideal for and applicable to all crystalline materials, especially for metals, but also for ceramics. It measures the absolute stress without the need for an unstressed sample for calibration.

Stresstech Group’s Xstress 3000 G2/G2R represents advances in design and construction, which provide enhanced reliability and function in the first truly portable X-ray stress analyzer.
