DT100DL

Description

The DT 100 DL is in accordance with ASTM D7899 method.
One of the primary functions of a lubricant is to preserve the cleanliness of a combustion engine's mechanical parts.
The cleanliness of the mechanical parts is facilitated by "detergency" and "dispersancy" (DD) additives in the engine oil.
The dispersancy is the property that allows the oil to suspend and carry away "pollutants" of diverse sources such as soot from combustion, metallic particles from wear, corrosion of mechanical parts, and insoluble products resulting from the ageing of the oil, etc.
Dispersant additives in oil prevent agglomeration and sludge formation by dispersing contaminants.
With proper formulated oil, the soot will remain homogeneously suspended up to high concentration levels.
When soot load reaches a critical limit for current condition of the oil, a sudden loss of dispersancy leads to rapid agglomeration and deposition of soot onto machine surfaces.
Contaminants like water and/or glycol can quickly knock out dispersancy performance without an increase in soot load.
Unlike measuring soot concentration where numerous options exist, measuring dispersancy performance is a real challenge to the oil analyst.
DT100DL enables the control over the lubricant in use quality and the detection of contamiantion.
The DT100DL is the unique instrument that evaluates simultaneously and automatically the contamination index (solid content) and returns information about dispersion in oil in order to plan and predict maintenance issues.
DT100DL has been developed in collaboration with oil monitoring specialized labs (OCM).
The method is specially dedicated to oil and diesel.
The "Spot" method determines the dispersion, the contamination and oxidation of an used oil spot on a specific filter paper.
The method, used since many years, foresees the evaluation of the spot by an operator.

Phase 1 - a drop of oil is injected on a filter paper
Phase 2 - the drop spreads on the paper
Phase 3 - the oil with contained particles penetrate into the filter paper.
The oil that is properly dispersing soot and other insolubles produces an evenly graduated spot.
Dispersion characteristics of the oil are judged by how far oil drop spreads, how big the central sooty area is and how homogeneous the opacity of the spot is.
The opacity of the spot will provide information on the oil contamination level.
Though this method has proven effective, individual subjectivity in readings oil spots affects the reliability of results.
o help oil analysts taking most advantage of this valuable traditional technique the company AD systems in cooperation with a lab dedicated in Oil Conditioning Monitoring (OCM) has developped a modern automatic instrument DT 100 offering significant increase in accuracy and repeatability of measurements.
This new technique removes all the arbitrary aspect of the manual method.

DT100 DL

The DT100 takes a spot image with a built-in digital camera.
In seconds, the software scans and analyzes all the different areas of the oil spot and automatically calculates the quantitative quality parameters of a motor oil in service.
The instrument automatically displays measurements and the acquired image on the monitor.
Parameters:

– Dispersancy (MD): representing the capacity of the oil to maintain the insoluble in suspension. It is expressed by an index from 100 (ideal) to 0 (no dispersancy)

– Contamination Index (IC): representing the percentage of insoluble matters present in the oil (from 0.1 to 5%).
The instrument has two correlation for the contamination index:
- for diesel engines
- for marine diesel engines
The user can select one of the two correlation directly in the software.

– Combined performance rating (DP): a mathematical combination of both IC and MD parameters.
The DP is very useful to follow-up oil degradation in oil condition monitoring program.

Additional reported parameters:

- Spot diameter
- Spot mean Opacity
