1Extent of automation
If user perception behavior is used for analysis, then the method is simple to implement, but the analysis cannot be automated and shows variability
Solution Approach 1:
The patent replaces the mechanical/manual assessment method with an automated optical measuring system. The optical analyzing device with radiation transmitter and receiver automatically detects and quantifies oil mist deposition patterns, eliminating dependence on user perception behavior while providing objective, repeatable measurements.
Solution Approach 2:
The measuring system performs self-assessment through automated optical detection. The system independently analyzes the deposited oil particles on the deflector plate using light reflection principles, without requiring external user interpretation, thereby achieving continuous automated monitoring.
2Measurement precision
If a non-rotationally symmetrical pattern is deposited on the deflector plate, then automated optical analysis becomes possible, but the measurement system requires rotation mechanism
Solution Approach 1:
The patent employs a non-rotationally symmetrical pattern of micronozzles that deposits an asymmetric oil particle pattern on the deflector plate. This asymmetry is crucial because it creates distinguishable variations in light reflection when the plate rotates, enabling the optical system to detect and quantify oil deposition automatically through pattern recognition.
Solution Approach 2:
The deflector plate is rotated periodically during measurement, bringing different regions of the asymmetric oil pattern sequentially into the optical beam path. This periodic rotation allows the optical analyzing device to scan the entire pattern and accumulate data for precise oil quantity determination.

AI summary
An automated analysis method for an impactor used as a measuring transducer for the selective determination of oil mist or aerosols. The process includes the steps of rotating the deflector plate (5) of the measuring transducer (1) about the symmetry axis thereof and of determining the quantity of oil deposited by means of an optical analyzing device from the extinction of a light beam reflected from deflector plate (5) due to the alternation between the background and the pattern produced by the micronozzles (4).
