Overview
The PULUODY PLD-0203-16 Mobile Light Obscuration Particle Counter is an industrial-grade, field-deployable optical particle analyzer engineered for high-fidelity contamination monitoring in critical fluid systems. It operates on the light obscuration (LO) principle—where particles suspended in a flowing liquid stream pass through a focused laser beam, generating transient reductions in detected light intensity proportional to particle cross-sectional area. This method delivers direct, real-time quantification of particle concentration and size distribution without reliance on scattering assumptions or refractive index corrections. Designed specifically for demanding applications in aerospace, defense, power generation, and hydraulic system maintenance, the PLD-0203-16 integrates dual-laser narrow-beam sensing technology (7th-generation architecture) to ensure stable signal-to-noise performance across ultra-low to high-concentration regimes. Its modular sensor architecture supports configurable detection ranges from 0.03 µm to 3000 µm, enabling precise characterization of sub-micron wear debris, insoluble contaminants in aviation fuels, and coarse particulates in hydraulic reservoirs—all within a single portable platform.
Key Features
- Modular multi-sensor design: Selectable sensor modules (A–N) covering discrete size ranges—including ultrafine (5 µm) bands—with up to 1000 programmable channels and 16 user-defined binning configurations.
- High-resolution light obscuration detection: Seventh-generation dual-laser optical system optimized for low-coincidence measurement at flow rates up to 60 mL/min; resolution ≥90% per ISO 21501-4 requirements.
- Full compliance with international standards: Preloaded algorithms and calibration protocols aligned with ISO 4406:1999/2017, NAS 1638, SAE AS4059F, GJB 420B, ISO 11500, and DL/T 432—enabling direct assignment of contamination codes without manual interpolation.
- Integrated P6.4 analysis software suite: Embedded touchscreen interface (color LCD) with PC-compatible desktop version supporting statistical trend analysis, histogram generation, cumulative distribution plots, and automated report export (PDF, CSV, XML).
- Automated operational workflow: One-touch sample aspiration, programmable volume (1–200 mL), self-cleaning cycle using internal solvent flush path, and real-time viscosity compensation for offline and online sampling modes.
- Ruggedized mobile form factor: IP54-rated enclosure, battery-backed operation (optional), shock-mounted optics, and pressure-rated inlet manifold (0–31.5 MPa with integrated regulator) for direct connection to pressurized hydraulic circuits.
Sample Compatibility & Compliance
The PLD-0203-16 accommodates a broad spectrum of non-aqueous and aqueous fluids without pre-filtration or dilution. Validated matrices include aviation turbine fuel (Jet A-1, JP-5, JP-8), phosphate ester hydraulic fluids (e.g., Skydrol®), synthetic lubricants, transformer oil, diesel fuel, glycol-based coolants, and ultrapure water (UPW). It meets the physical and metrological requirements of military and civil certification bodies: calibration traceability is maintained via CSTIND Grade I Particle Metrology Station (for defense applications) or Northwest National Metrology & Testing Center (civil sector), both operating under CNAS accreditation. Instrument validation follows JJG 1061 and GB/T 18854-2002 protocols, with optional IQ/OQ documentation packages available for GLP and GMP environments. All firmware and software modules support audit-trail logging per FDA 21 CFR Part 11 when configured with electronic signature and role-based access control.
Software & Data Management
The P6.4 software platform provides full lifecycle data governance—from acquisition to archival. Each test record includes raw pulse-height histograms, time-stamped metadata (operator ID, location, ambient conditions), and configurable pass/fail thresholds based on user-defined limits or standardized contamination classes. Data export supports interoperability with LIMS platforms via MODBUS TCP/IP, RS485 serial, or USB mass storage. Analog outputs (4–20 mA, 0–5 V) enable integration into SCADA or PLC-based condition monitoring networks. Internal memory retains up to 6000 test summaries (200 tests × 30 result sets), while optional cloud synchronization with PULUODY Oil Monitoring Cloud System enables remote fleet-level analytics, predictive maintenance modeling, and cross-site benchmarking. All reports comply with ISO/IEC 17025 documentation integrity requirements.
