Flexible production systems in the sheet processing industry require automated, reliable double
sheet detection in order to protect presses and other processing machinery from damage by
multiple sheets. The E20 was specifically developed for this technical environment.
The E20 is based on the product platform R1000 and consists in the standard version of three
components:
• Control unit
• One sensor for ferrous materials
• Sensor cable

3.1 Measurement principle
The double sheet detector is based on the electromagnetic principle. It monitors ferromagnetic
sheets with single sided sensors and exerts forces during the monitoring process only. A change of
the sheet thickness results in a change of induction. The system calculates the sheet thickness
from this change. Corresponding to the pre-set limits 0-sheet, 1-sheet or 2-sheets signals are
generated.
