Innovative laser line technology
Laser line technology offers several advantages: signal gaps caused by steam or particles do not affect the measurement. Sheet tilting can also be detected and compensated for. As a result, the thickness accuracy is identical for flat sheets and tilted sheets. The laser line can also detect sheet edges.
Optical gauges for highest precision
The laser scanners preferred in the thicknessCONTROL systems offer numerous advantages in thickness measurement. Two types of laser are available - the red laser is used for measurement tasks in the cold rolling area. The patented Blue Laser technology is used in the metal industry, especially for red-hot metals. The blue laser light uses a different wavelength range than red laser light, which means that the laser line is formed sharply on the measuring object and is focused sharply on the sensor element. Special filters prevent the sensor from being blinded by the radiation of the glowing target. This results in much more stable and reproducible measurement signals.
