Overview
The XY500S Textile-Specific Electronic Balance is an industrial-grade analytical balance engineered exclusively for yarn and fiber metrology in textile laboratories and quality control environments. Unlike general-purpose balances, the XY500S integrates real-time linear density calculation algorithms compliant with internationally recognized textile standards—including ISO 2060 (determination of yarn linear density by mass per unit length), ASTM D1907 (standard test method for linear density of yarns), and GB/T 14343 (Chinese national standard for synthetic filament yarn). Its core function is not merely mass measurement but the direct derivation of seven standardized textile count units from a single weight reading: English count (Ne), metric count (Nm), tex (g/km), denier (g/9,000 m), ounces per square yard (oz/yd²), grams per square meter (g/m²), and ounces (oz). This eliminates manual conversion errors and accelerates sample throughput in QC workflows where rapid, repeatable determination of yarn fineness or fabric basis weight is critical.
Key Features
- Precision weighing platform with 0.01 g readability and 510 g maximum capacity—optimized for small-diameter yarn hanks, filament bundles, and cut fabric specimens.
- Dedicated textile unit conversion engine enabling one-touch switching between Ne, Nm, tex, denier, oz/yd², g/m², and oz—each calculated in real time using calibrated mass input and user-defined specimen length or area.
- Stainless-steel weighing pan (Φ130 mm) designed to accommodate standard textile test specimens including skeins (e.g., 120-yard hanks for Ne), warp beams, and swatches up to 30 × 30 cm.
- Tare function with memory retention for sequential multi-sample weighing under identical tare conditions—essential for batch testing of spun yarns or filament reels.
- Robust mechanical architecture featuring electromagnetic force compensation sensor technology, ensuring long-term stability and resistance to ambient vibration common in factory-floor labs.
- Compliance-ready interface options: RS232 and RS485 ports support integration with LIMS or QA documentation systems; optional thermal printer enables GLP-compliant hardcopy traceability.
Sample Compatibility & Compliance
The XY500S is validated for use with all major textile material classes: cotton, wool, polyester, nylon, viscose, PTT, and blended fibers. It supports standard test methods requiring precise mass input for linear density calculations—including wrap reel measurements (ASTM D1059), lea tests (ISO 2060 Annex A), and fabric basis weight determination (ISO 3801, ASTM D3776). The balance meets electromagnetic compatibility (EMC) requirements per IEC 61326-1 and operates within Class II environmental specifications (IEC 60068-2) for laboratory and light industrial settings. While not certified to OIML R76 or NIST Handbook 44 for legal-for-trade applications, its performance aligns with internal QC thresholds defined in ISO/IEC 17025-accredited textile testing laboratories.
Software & Data Management
No proprietary software is bundled; however, the XY500S outputs ASCII-formatted data via serial interface in standard weight + unit code format (e.g., “52.34 g”, “18.7 Ne”), compatible with Excel, LabArchives, and custom SQL-based QA databases. All communication adheres to Modbus RTU protocol over RS485 for deterministic polling in automated test stations. Audit trail functionality is enabled when paired with external timestamped logging—supporting FDA 21 CFR Part 11 compliance when implemented with electronic signature controls in enterprise QA systems. Firmware updates are performed via USB-to-serial adapter (not included).
Applications
- Yarn count verification during spinning mill process control and final inspection.
- Linear density validation of filament yarns prior to weaving or knitting.
- Basis weight measurement of nonwovens, knits, and woven fabrics per ISO 3801.
- Research-grade characterization of novel bio-based or recycled fibers in academic textile engineering labs.
- Calibration reference for secondary instruments such as automatic yarn testers (e.g., Uster Tensorapid).
- Training tool in university textile science curricula for hands-on instruction in metrological principles of count systems.
FAQ
Does the XY500S meet ISO/IEC 17025 calibration requirements?
Yes—the balance is supplied with a factory calibration certificate traceable to NIM (National Institute of Metrology, China) standards. Users must perform periodic in-house verification using Class M2 weights per ISO 17025 Clause 6.5.
Can it calculate Ne directly from a 120-yard hank?
Yes—enter hank length (120 yd) and measured mass; the instrument applies the formula Ne = (length in yards × 840) / mass in pounds, automatically converting grams to pounds internally.
Is draft shielding included?
A removable acrylic draft shield is available as optional accessory (part no. DS-XY500); it is recommended for environments with air currents exceeding 0.2 m/s.
What is the warm-up time required for full accuracy?
Minimum 30 minutes at stable ambient temperature (20 ± 2 °C) before initiating GLP-critical measurements.
How is repeatability verified?
Per ISO 9001 Annex B, repeatability is assessed using three consecutive weighings of a 200 g Class M2 weight; typical standard deviation is ≤ 0.015 g under controlled conditions.
