• Ensure minimum exhaust emission
requirements with two systems that measure additive depletion/oxidation
and soot contamination.
• Real-time measurements.
• Optimize resources by directly comparing additive package
performance under actual test conditions without operator intervention.
• Temperatures up to 150°C.
• No more sampling & analysis.
• Save time with easy set-up and operation.
• Specifically designed to fit test facility engines.
• No standards or calibration required.
• Compatible with oils of different composition and
• Assured operation with an innovative technology that
utilizes the electrical properties of an insoluble polymeric bead
matrix. A measured change in the beads electrical properties result
when their interactive behavior adjust to a change in the solvent
properties of the oil.
||The Oil Insyte Oil
The Oil Insyte Monitoring System introduces
an in-line method for continuous oil condition monitoring with an easy
to read LCD display. The methodology measures the leading indicators of
oil wear and allow the conventional two-step approach of oil monitoring
(sampling and analysis) to be combined into a single more efficient
step. A common protocol allows for easy side-by-side comparisons for
correlating oil type to driving environments and conditions. The
Oxidation System independently measures additive depletion and
oxidation, providing the ability to examining the interdependence
between the two for ensuring maximum lubrication performance. The Soot
System determines soot contamination and provides the ability to
measure additive package performance by determining the amount of free
soot present in the oil for protecting engines and catalytic
converters, ensuring low exhaust emissions compliance, and maximizing
The Oil Insyte System provides for directly comparing additive package
performance by measuring the leading indicators of oil wear under
actual test conditions without operator intervention. Specifically
designed to fit test facility engines, each system provides easy set up
and operation. The methodology does not require external standards or
calibration, is independent of an oil’s viscosity, and is
compatible from 70 – 150°C (as measured in the
The Oil Insyte uses a patented technique that employs a polymeric bead
matrix (held between two conducting permeable surfaces) containing
charged groups that serve as a conducting medium for measuring the
solvent properties of oil. Taking a relative ratio of the conductivity
of the beads to the conductivity of the oil (bead chamber to open
chamber) determines the oxidation state of the oil. A ratio of the two
signals effectively subtracts out additive effects and provides a
unique method for measuring oxidation in isolation. The sensor is
optimized for oxidized oils measuring between 20 - 26 OD/cm by infrared
(IR) spectroscopy, considered the optimum oil change interval for
automotive oils given a scale of 1 - 33 OD/cm.
Soot measurements are based on a percentage of the saturated relative
contamination (SRC), i.e., the amount of freely available soot in the
oil. Like water, a percentage of soot is normally contained by an oil's
additive package. When that threshold is exceeded, soot is available
for coming in contact with the sensor and triggering a response. The
free soot (composed of carbon) sticks to the surface of the beads
forming a "bridge" across the chamber providing a relative increase in
conductivity. Depending on the oil's additive package, the same amount
of free soot can be present at 1-2% contamination (for base oil without
additives) to > 7% for fully formulated oils.
The Oil Insyte system consists of a sensing element, a mechanical
interface (that secures to the oil reservoir) and a signal-conditioning
unit with an easy to read LCD that displays the condition of the oil.
Values for oxidation, additive depletion, and temperature are displayed
on the Oxidation System. Soot and temperature are displayed on the Soot
