Which industries use
inline instruments are used for ingredient measurement and process
control in the beer, soft drink, spirits, pharmaceutical, food,
bioethanol and industrial manufacturing industries. Any
industry which requires real-time measurement of dissolved CO2,
Alcohol, Gravity, Sugars/Brix,
or Organic Acids (TA) is a potential user our sensors.
What is the technology
behind VS Series Sensors?
are solid state, mid-infrared spectrometers that provide
concentration readings of dissolved ingredients
in fluids. VS series sensors use Beer-Lambert's Law and Attenuated Total Reflection
Spectroscopy to directly measure the molecules of interest.
MID-Infrared (MIR) is preferred over NEAR-IR (NIR) and mechanical methods
because of the ability to separate molecules. This method provides a
direct, real-time measurement; ingredient concentrations are not
extrapolated using calculations.
What is an inline sensor?
sensor is a device that operates in-situ (directly inside of a pipe
or tank); meaning liquid fluid passes over the measurement crystal
versus being drawn into an offline chamber or slip-stream pipe.
In-situ sensors are the most precise, reliable
and sanitary sensors on the market.
What are the benefits of
direct infrared measurement?
measurement has proven to be more accurate and
reliable when compared to mechanical measuring methods
VitalSensors instruments only measure the specific ingredients of interest; they are not affected by
physical charaterisrics ina fluid.
When measuring CO2 for example, it is important to note that traditional temperature/pressure
instruments infer CO2 content by adding estimates of other gases,
using a specific gravity constant, and relying on variable
temperature and pressure.
By contrast, a direct molecule measurement (via infrared) is more precise
and will not be affected by a pressure or temperature fluctuation.
VitalSensors products only measure the specific molecules of interest
and are blind to potential interference such as solids, density
changes, viscosity or
Are VS Sensors
affected by density, color, turbidity or pressure?
No, because the
sensor are infrared
instruments, the density or specific gravity of a liquid has no
affect on the concentration measurement. VS series sensors are
looking only at the molecules of interest utilizing IR filters cut
specifically to see the ingredient of interest. This is significantly
different from temperature-pressure, mass-flow or density
instruments that often have to correct their readings and are by
nature, indirect methods.
Can the VS-3000 Sensor Systems
see my CIP cycle?
series sensors, CIP cycles can be measured and tracked
by the temperature changes and concentration changes in the CIP fluid.
These changes occur instantaneously upon initiation of the CIP
cycle, therefore, VS series sensors can immediately report liquids
transition from production conditions to CIP conditions.
What sort of maintenance do VS
VS Sensor Systems require
no routine maintenance. Because our sensors are based on solid state technology,
no moving parts. Standard CIP cleaning cycles insure a clean crystal
and routine weekly reference measurement checks are all that is
What are the components of a
VS Sensor System?
A standard VS-3000
or VS-1000 Sensor System includes
the Sensor head, the VS-300 or VS-200 Sensor Management Station, Dashboard Software
and sensor cable. The system is sold and shipped as a package with
one price. Appropriate fieldbus connectors and wiring guides
are shipped standard.
What types of networks are
VS-3000 systems support
Allen-Bradley EtherNet/IP or Siemens ProfibusDP. All VS-3000
sysems are designed to be integrated into plant ethernet/control
networks for Remote Access/Mainteneance
How long will it take to
install a sensor?
Assuming that the correct fitting and power are
already in place, it takes less than 30 minutes to install a system. A 10mm
wrench, power cable, Varivent
fitting and a place to mount the VS-300 or VS-200 Sensor Management Station
are all that is required.
How do VS Sensor System
economics compare to the competition?
Products have significant economic
advantages over traditional temperature/pressure or density measurement
devices. Acquisition costs are less and maintenance and support
costs are significantly less. VitalSensors products are
proven to reduce false production alarms and unnecessary downtime.
MTF > 50,000 hours.
What type of support can I
expect from VitalSensors Technologies?
VitalSensors offers on-site
field commissiongs services and support contracts. During a
typical commissioing, VitalSensors provides 4 days of on-site
calibration support, programming support and training.
