Surface Roughness (Subscribe)



On-line inspection of surface roughness becomes more and more important. AMEPA offers a new generation of systems allowing the on-line and contact less measurement of the surface roughness values Ra, Rz and Rpc. It is the first system providing a measurement under 45° or 90° to the rolling direction - as requested by the norms as SEP 1940. Key features are independence of sheet surfaces, automatic calibration, high measurement frequency of up to 20 hertz, microscopic images of the sheet surface, ...

SORM 3plus (SORM = Superfast Optical Roughness Measurement) is the 3rd generation of an innovative system enabling online measurement of roughness parameters on moving strips. Increased requirements for new materials and more complex components call for ever increasing process safety. SORM 3plus has been designed for applications even on fast or very fast production lines (such as processing or temper processing lines). SORM 3plus detects the surface roughness of a moving strip over the length and the width of the processed material. SORM uses an optical scanning method to measure the microprofile of a surface. This surface profile can be compared to the profile which is detected by a stylus instrument. Then the measured profile is taken as a basis to calculate the roughness parameters (Ra, RPc, Rz) according to the applicable standards (DIN / ISO / SEP).
