AMepa - Model SRM 100 -Online Roughness Measurement System

Precise

• Measuring range of Ra 0.3 to 3 µm,
  RPc 30 to 120 cm ^-1 ,
  resolution for Ra with 0.01 µm
• For automotive grades with high accuracy at ± 10% for tactile measurement
• Measuring frequency up to 100 Hz, short response times, high dynamics
• Ra measurements with selectable cut-off of 0.8 or 2.5 mm
• View field of 1.2 х 0.4 mm,
  measuring line of 1200 х 3.5 µm
  (≈ spatial resolution like a stylus tip)

Efficient

• Insensitive to vibrations and strip oscillations, measurement capability up to 2000 m/minute and higher strip speed
• Reduction of time-consuming and sample-intensive stylus measurements, while maintaining the very high correlation with the stylus measurement
• Measuring is possible regardless of lighting conditions and also possible when the strip is stationary

Informative

• Documentation of measurement data of relevant roughness parameters with image evidence from the beginning to the end of the coil
• Microscopic image of the surface structure
• Validation unit for measurement integrity and measurement equipment capability studies

Versatile

• Non-contact measuring on all quality surface areas made of steel (Z, ZE, ZF, respectively EDT, EBT or PRETEX texturing) and aluminum (mill finish and EDT)
• Acquisition of Ra, RPc and Rz in one measurement recording, adjustable to traversing measurement tracks (eg for strip center, strip edges)
• Measuring angle at 90 degrees to the rolling direction (requirement from DIN EN ISO 10049), optionally with 45 degrees
