Shadyscan Plus

Laser Shadow & Eddy-Current Scanner

SHADYSCAN PLUS is a non-contact profile thickness measuring system that uses the signal of a through-beam sensor to measure sheet thickness. ShadYscan PLUS has many applications; in particular, it is suitable to measure the thickness of expanded sheets, higher than 3,5 mm, that cannot be measured with absorption systems such as X-rays and capacity-based systems.

The light beam is aimed tangentially to the surface of the sheet and redirected over the measurement roller. The through-beam is collected by a CCD camera which monitors the increase and decrease of the shadow generated by the sheet. This measurement is created detecting the shadow generated by the sheet, setting the shadow of the roller at the zero point.
