Non-contact thickness measurement for cardboard and paperboard

Physical principle:

Non-contact thickness measurement by means of a magnetic field moving on air cushions. The changes in the distance between the sensors generate an indicated voltage and thus a change in frequency.

Application range:

On paper, cardboard and paperboard webs from 0.3 mm thickness.  Other web-shaped products can also be measured.

The sensors require a sensor arrangement on both sides.

Special feature:

Available single point and scanning.
