Oil Liquid Abrasive Particle Intelligent Detector
Project Overview
The Oil Wear Particle Detector (EIDCS-1A) is designed for high-precision, high-volume fluid sampling, and frequent testing scenarios. The product was demonstrated and validated on-site at the Daishan and Benniu Airbases of the East Sea Fleet, where it was used to analyze lubricating oil from various aircraft engines. The successful trials confirmed its key features, including high intelligence, accurate built-in standard calculations, user-friendly operation, and efficient data storage capabilities. Detailed results can be found in the trial report.
Konghang International has decades of technical expertise within the aviation industry, particularly in aircraft engine research and development. Our team includes leading experts and extensive technical resources focused on engine systems, with in-depth knowledge of various engine models and their maintenance requirements. We have developed numerous specialized testing equipment for engines, including over 100 units of the "EIDCS-1A" Oil Wear Particle Detector, which has been delivered to both the Air Force and Navy. This device, also known as the Oil Wear Particle Analyzer, Large Particle Analyzer, or Automatic Wear Particle Detector, is highly effective for detecting engine faults, oil contamination levels, wear particles, and debris in various military aircraft engines. Currently, hundreds of units are in service with the Air Force, and dozens with the Navy. Our proprietary intelligent control software and functional modules provide unique capabilities for real-time engine oil monitoring.
Given its critical role in engine condition monitoring, the device has been officially recognized through the issuance of a Technical Bulletin, highlighting its irreplaceable importance in maintaining operational safety and efficiency.

Working Principle
In the fluid channel, oil is driven by an automatically controlled peristaltic pump through an optically precise sample cell, which is installed in a transmission-reflection optical path lighting system. A long-focus microscopic optical lens, controlled by a computer for automatic focusing and tomography, performs real-time dynamic imaging of particles in the oil flowing through the sample cell. After the particles in the fluid are magnified and imaged, the image signals are captured by a high-speed CCD, then transmitted to the computer for processing via an image acquisition card (A/D). The computer system analyzes the collected particle images through software to identify the morphological characteristics of the particles, determine the type and quantity of abrasive particles, and assess the oil contamination level. This enables monitoring of the wear status of the engine system, fault trend analysis, and expert diagnosis.
