Sophisticated multi functional online permeability sensor scanner
systems. Patent pending DE10251610, granted in China 200310104764.
Stationary or scanner systems for high speed moving fabrics or
sheet material to detects very precise and reproduce specified
product properties, natural or micro perforated porosity levels
during production. OPSS-1 OPRL-1 vision control systems are
equipped with multiple IR, NIR, VIS monolithic spectral color
sensors, precision line lasers, CCD image devices, DSP, ATMEL,
INFINEON sensor internal controller, firmware, fast serial data
link, scanning speeds 20-500mm per second, web widths up to 5,
000mm, measuring gaps from 2.0-5.0mm, optical inline detection of
permeability, porosity, spectral transmission, opacity, extinction,
particle absorption. Porosities ranges 80 up 5, 000 C.U. respective
from 50 down to 3 Gurley, position control of micro perforation
lines with 0.1mm accuracy, 0.050-200 microns pore diameter by up to
300 pores per cm2. With real time data determining of certain
parameters, optical transmission, spectral grades, porosity
integrals, envelope curves, internal calculated measuring values.
Thus direct with close loops and feedback to power electronics of
fabrics treatment units. Micro perforation or other treatment
system makes it possible to compensate any changes in web treatment
parameters and their partial locations so that each jumbo roll as
well single, twin or quad bobbin sets can be produced quantity and
quality controlled without intermediate stops in order of
ISO9001/9002 certifications. Working principle and application.
Thus sophisticate, precise, liable, repeat accuracy, easy
visualized, optical online measurement techniques archives perfect
ways to control and convert pneumatic, fluid, gas, jet streams,
static permeability, naturally porous grades, filtration levels,
breathable or ventilation effects. Their conditions can be easily
met by using optical transmission technology.
