3D ORM 측정기술의 장점 |
• Only particles, which are in the 3D focus point, are solely and continuously detected by an extremely confined and selective focus.
• Only the patented 3D ORM sensors have a dynamic focus. The user obtains reproducible measuring results with MTS patented measuring procedure.
• The focus moves continuously horizontally, within the “Travelling
Distance TD”
from the sapphire window, inside the
medium. Because of this the focus from the
window
is very small and fine particles with 0.14 micron can be detected.
When
travelling in the medium the focus optically
widens and can therefore selectively
detect larger
particles up to 2400um.
• At the same time the focus point rotates, which creates a cylindrical
path in which
the focus dynamically wanders with
even scanning speed inside a spiral motion.
The speed of the moving focus is in all directions 2 or 4m/s.
• The single fibre optics have a extreme small opening angle.
That way all signals
resulting from multiple counts
are already sorted from the sensor optics. Only
particles
which have generated a signal in front of the focus will be used
for the
statistic of the signal length distribution.
• All adjustments on the sensor have already been made at the
production, so that
operating error by the customer
can be ruled out.
• The focus is always very narrow and at the same time proportional
to the
geometrical area in which it is placed.
In this way, signals are avoided through
multiple
dispersion.
• MTS places the focus point in front of the sapphire window
in order to avoid the
focus from widening, which
could amount to the characteristic of turbidity
measurement
and only simulate non selective signal rates and high number rates.
• Special structural shapes are available for applications, where
the beginning of a
nucleation must be observed and
through these nucleations the turbidity effects
can
be put to good use (PSyA CSD).
• Sensors, which take into account the special backscattering
characteristic of
emulsions o/w and w/o in the range
of <30 / 60 microns, can be used for
measuring
drop sizes in high concentrated emulsions up to CV 70%.
