OASYS®
Hardware
|
| OASYS® works virtually and sees just like the human
eye. The OASYS® Measuring
System operates on the principle of absolute optical measurement
using infrared light. It “sees” yarn defects just like the human
eye: thick and thin places, irrespective of whether these areas
contain more or fewer fibres (greater or less mass) than the normal
yarn. The capacitance evenness testers used today fail to provide
meaningful information on the quality of the end-product.

 |
The structure of a yarn is subject to variations of a periodic or
random character. The measuring system compares the yarn diameter
with the constant reference mean and records variations in length
and diameter. The yarn testing module use an infrared light sensor
operating with a precision of 1/100 mm over a measuring field length
of 2 mm and at a sampling interval also of 2 mm. The speed of
measurement may be selected on a graduated scale between 100 and 400
m/min.

|
The sensor
operates in any environment with equal precision, both in the
laboratory and under production conditions: |
-
it is unaffected by ageing of the light source,
extraneous light, contamination, temperature and humidity
-
it is unaffected by such yarn characteristics as
colour, conductivity or lustre
|
|
|
The essential function of the OASYS® SYSTEM lies in
its ability to simulate yarn irregularities on boards and woven and
knitted fabrics using the previously measured yarn data. |
