Roughness measuring system WMS 100

corrugationlaserfor sheet materials

AMEPA online measurements of the surface area profile provide fundamental advantages for the customer: Visualize and document the waviness and roughness distribution over the entire length of the coil or strip Efficiently detect waviness values and roughness values outside the tolerance, which can be caused by Incoming roughness of the raw material Wear of work rollers Incorrect process parameters Provide online data to determine the optimum time for changing the work rolls Provide the Wsa roughness value and the Ra roughness value as an input for process control Reduce the number of offline measurements with stylus instruments The Benefits Precise Measuring range for Wsa from 0.1 to 1 µm, measuring range for Ra from 0.3 to 3 µm, RPc 30 to 120 cm-1 Triggering for Wsa 0.001 µm, triggering for Ra 0.01 µm Measurement frequency for Wsa measuring up to maximum 1 Hz Ra measurements with selectable cut off of 0.8 or 2.5 mm WMS measuring parallel to rolling direction View field of 1.2 х 0.4 mm, measuring line of 1200 х 3.5 µm (spatial resolution like a stylus tip) Efficient Reduction of time-consuming stylus measurements on the line and in the laboratory Wsa measurements possible up to a strip speed of 180 m/minute Punctual detection of waviness values, which are outside the specified tolerances, for optimal process control, short response times, increased dynamics Versatile Measuring independently of light conditions Contactless measurement on all quality surface areas, aluminium (mill finish and EDT) or steel (Z, ZE, ZF) each in EDT, EBT or Pretex texturing
