ERACOUNT XS Portable Laser-Based Particle Counter by ERALYTICS

Overview

The ERACOUNT XS is a portable, fully integrated laser-based optical particle counter engineered for rapid, field-deployable cleanliness analysis of lubricants and petroleum-based fluids. Unlike benchtop systems requiring laboratory infrastructure, the ERACOUNT XS implements light extinction (single-particle optical sensing) in a compact, ruggedized housing—enabling ISO-compliant particle counting directly at the point of use: hydraulic reservoirs, turbine sumps, gearboxes, or service trucks. Its measurement principle adheres strictly to the photometric detection methodology defined in ISO 11171, where particles passing through a focused laser beam induce transient reductions in transmitted light intensity, with pulse amplitude correlated to equivalent spherical diameter (ESD). The instrument reports results in standardized ISO 4406 code format across eight calibrated size channels (4, 6, 14, 21, 25, 30, 38, and 70 µm(c)), ensuring direct comparability with global maintenance benchmarks and OEM fluid specifications.

Key Features

• Field-ready operation: Complete ISO 4406 reporting in ≤30 seconds with minimal sample volume (5–12.5 mL), eliminating need for off-site lab submission.
• Full compliance architecture: Factory-calibrated per ISO 11171 using NIST-traceable latex sphere standards; validated against ISO 4402 and SAE AS4059 protocols.
• Viscosity-tolerant fluid handling: Integrated flow control accommodates oils up to 1000 cSt at 22 °C (equivalent to ISO VG 320), enabling direct analysis of turbine, gear, and compressor lubricants without dilution.
• Robust mechanical design: All-metal enclosure, IP54-rated ingress protection, and shock-absorbing internal mounting ensure reliability in industrial environments—including offshore platforms, wind farms, and mobile maintenance units.
• Modular interoperability: Native digital interface (RS-232/USB) enables synchronized data exchange and automated workflow integration with other ERALYTICS instruments—e.g., ERAVISC X kinematic viscometer or ERASPEC OIL FTIR spectrometer—for multi-parameter oil condition monitoring.

Sample Compatibility & Compliance

The ERACOUNT XS is validated for use with mineral oils, synthetic hydrocarbons, phosphate esters, and polyalkylene glycols within the specified viscosity and temperature ranges. It supports both offline sampling (bottled extracts) and online bypass configurations via optional flow cell kits. All reported particle counts satisfy the metrological traceability requirements of ISO/IEC 17025-accredited laboratories and are compatible with predictive maintenance frameworks governed by ISO 4406:2017, NAS 1638, and SAE AS4059F. Instrument firmware includes built-in audit trail logging (user ID, timestamp, calibration status, sample ID), supporting GLP and GMP-aligned documentation practices under FDA 21 CFR Part 11 when deployed in regulated manufacturing or power generation settings.

Software & Data Management

Data acquisition and reporting are managed via ERALYTICS’ proprietary CleanTrack™ software suite (Windows-compatible), which provides real-time visualization of differential and cumulative particle distributions, trend charting across multiple sampling points, and automated generation of ISO 4406-coded certificates compliant with OEM reporting templates. Raw pulse data and metadata—including flow rate, temperature, pressure drop, and calibration certificate ID—are stored in encrypted .csv and .xml formats. Software supports configurable pass/fail thresholds per size channel, automatic flagging of deviation from historical baselines, and export to LIMS or CMMS platforms via ODBC or API endpoints. Audit logs retain full revision history of method parameters and user actions, satisfying ALCOA+ data integrity principles.

Applications

• Hydraulic system cleanliness verification prior to commissioning or after filter change-out.
• Routine oil health assessment in wind turbine gearboxes, where early detection of wear debris >25 µm(c) correlates strongly with bearing spalling progression.
• Acceptance testing of new lubricants per ASTM D7619 and ISO 4406 Class limits.
• Root-cause analysis of servo-valve failures in aerospace ground support equipment.
• Condition-based maintenance scheduling for marine diesel engine crankcase oils, integrating particle count trends with viscosity and oxidation data from co-located ERALYTICS analyzers.

FAQ

Does the ERACOUNT XS require annual recalibration?
Yes—per ISO 11171 Section 7.2, calibration verification must be performed at least annually using certified reference materials; ERALYTICS recommends semi-annual verification for high-utilization field units.
Can it measure particles in water-glycol hydraulic fluids?
No—the optical design and wetted path materials are optimized for hydrocarbon-based fluids; aqueous or highly polar media may cause refractive index mismatch and sensor fouling.
Is sample filtration required before analysis?
Not unless particulate loading exceeds 20,000 particles/mL in the 4 µm(c) channel; the instrument’s dynamic range and self-cleaning flow path minimize clogging risk under typical in-service conditions.
How is temperature compensation handled during measurement?
An integrated Pt100 sensor monitors sample temperature in real time; viscosity-dependent flow corrections are applied algorithmically using the ASTM D7042 correlation model embedded in firmware.
What cybersecurity safeguards are implemented in CleanTrack™ software?
Role-based access control (RBAC), TLS 1.2 encrypted communications, hashed password storage, and FIPS 140-2 validated cryptographic modules meet IEC 62443-3-3 SL2 requirements for industrial control systems.
