infrared ATR probes are highly-selective and highly-accurate inline
Multi-parameter ATR Sensors are a step ahead of alternative methods.
VitalSensors producs do not extrapolate concentrations using pressure, density
or sound velocity. The optical ATR method is not affected by solids,
variable pressure, viscosity, turbidity or dark-colored fluids. Therefore, VitalSensors offers Quality
personnel with the highest level of accuracy.

VS-3000 ATR Optical Sensors
VS-3000 sensor probes are compact,
industrial-grade, mid-infrared spectrometers.
sensors measure the contents of
liquids directly and with great precision. A common physics
package accommodates various narrow-band-pass interference filters
for each detector element and isolates these specific infrared
wavelengths for the component being measured. A highly accurate thermistor to measure
temperature and an optical element that creates infrared absorption
by means of ATR or Trans-ATR are key components of the
generation of VitalSensors products measure up to 9 process
variables using only 1 infrared probe / process connection.
Infrared spectroscopy works because chemical
bonds have specific frequencies which vibrate at corresponding energy levels. The resonant frequencies are determined by the
shape of the molecular potential energy surfaces, the masses of
the atoms and eventually, by the associated vibronic coupling. In
order to measure a sample, infrared light is passed through the
sample, and the amount of energy absorbed by the substances chemical
bonds is recorded. Over the years, detailed absorption tables
of bonds in organic molecules have been developed and are used to
identify and measure samples very precisely. VitalSensors products
use the Beer-Lambert Law which is central to molecular spectroscopy.
Beer-Lambert allows for determination of the Molar Absorptivity, a
characteristic which indicates how much light of a particular wavelength
a sample absorbs.
Today infrared spectroscopy is widely used in laboratories and for
quality control. Most of these instruments are extremely expensive. One of VitalSensors core company goals is
in-line, infrared, instruments affordable for large-scale deployment in
process control applications.
VS-3000 Sensor Systems are solid state devices which contain no moving parts.
Therefore there are no recurring maintenance or ancillary hardware
instrument is designed to operate 24x7. Mean time to failure is over 50,000 hours.
