Optical in-line
permeability - porosity - measurements
Porosity measuring of porous and/or perforated (
with laser or electrostatic perforation systems ) web material which are
produced in speed ranges up to 600 m/min and web widths up to 2000 mm are
difficult with pneumatic systems because this methods includes disadvantages
such as web tangency, web toughing, material flaking, folds build-up, dust and
dirt flowing in the system. This difficulties are ideally overcome with
stationary, optical porosity measurement systems.
Also offered the production technique to
perform scanning zone area measurements using multiple sensors and computer
controlled. The systems can control material web widths up to 2000 mm ( or
bobbin formats ), stand-along or mechanic coupled with existent scanning units
which measure the material weight, thickness, formation,
etc.
