Laser optical surface roughness measurement device [SORM]
Laser optical surface roughness measurement device [SORM]
Roughness on the surface of thin steel plate rollers can be measured with no contact through use of a laser.

Roughness on the surface of thin steel plate rollers can be measured with no contact through use of a laser.
Features
Conventional roughness measurements using a sensing pin required production lines to be stopped or samples collected for off-line gauge measurements made in a laboratory. The SORM 3plus has realized in-line measurements.
Utilization of this device allows the quality of steel plates to be improved and the timing of roller replacement more easily scheduled.
