The PDA100 portable automatic wear particle analyzer is a portable instrumentation system based on video streaming, high acquisition rate, dynamic imaging analysis, and intelligent wear particle recognition and classification. This instrument is primarily designed for monitoring contaminants in engine lubricating oil, aircraft hydraulic oil, aviation fuel, and transformer oil. It can automatically sample oil specimens of varying viscosities and directly capture morphological images of particulate contaminants. The built-in automatic abrasive particle intelligent recognition algorithm software calculates the area and equivalent circular diameter of particle contaminants in accordance with ISO 11171, and outputs the quantity and classification of the particles. It enables counting of particles larger than 4 μm, concentration measurement for particles between 5–10 μm, and automatic classification of particles larger than 20 μm into categories such as cutting wear, sliding wear, fatigue wear, non-metallic abrasives, fibers, water droplets, and bubbles, with concurrent direct image visualization.
