YANRUN YRWT-M200 Microcomputer-Controlled Electromechanical Universal Testing Machine

Overview

The YANRUN YRWT-M200 is a microcomputer-controlled electromechanical universal testing machine engineered for high-precision static mechanical property evaluation of metallic and non-metallic materials under tension, compression, bending, peel, shear, and flexure loading conditions. Based on the fundamental principles of force transduction via precision load cells and displacement measurement through high-resolution encoder feedback on a preloaded ball-screw actuation system, the YRWT-M200 delivers repeatable, traceable, and standards-compliant test data across diverse industrial and research applications. Its dual-accuracy configuration—offering either Class 0.5 or Class 1 performance per GB/T 16491 and ISO 7500-1—ensures suitability for both quality control laboratories requiring routine compliance verification and R&D environments demanding metrological rigor. The system operates within a rigid, vibration-damped frame and integrates real-time closed-loop control to maintain programmed strain or load rates with minimal deviation.

Key Features

• Full digital closed-loop control architecture with independent host–PC operation capability
• Automatic zeroing, auto-return-to-initial-position, and auto-data archiving upon test initiation
• Dual-speed crosshead movement: rapid positioning (manual) and programmable test-speed regulation (0.1–500 mm/min)
• Integrated electronic and mechanical dual-limit protection, plus over-load shutdown at 110% of full-scale capacity
• Real-time dynamic display of force–displacement, stress–strain, and time-based curves during testing
• Post-test curve traversal: point-wise extraction of force, displacement, and deformation values using mouse navigation
• Multi-curve overlay and comparative analysis with customizable color coding and scaling
• Configurable report generation supporting standardized outputs (e.g., tensile strength, yield strength, modulus of elasticity, elongation at break, compressive strength) and user-defined templates
• Self-diagnostic subsystem continuously monitors drive voltage/current, thermal status, and sensor integrity; triggers immediate halt upon anomaly detection
• Emergency stop button with hardwired cut-off to main power supply for operator safety

Sample Compatibility & Compliance

The YRWT-M200 accommodates specimens ranging from fine metal wires (diameter ≥0.1 mm), thin foils (<0.05 mm), polymer films, textile yarns, and PCB substrates to structural metal rods (up to Ø30 mm) and ceramic tiles. Standardized grips—including wedge-action tensile jaws, compression platens, 3-/4-point bend fixtures, peel testers, and shear adapters—support seamless transitions between test modes. All hardware and software functions comply with national and international metrological and procedural standards: GB/T 2611 (General Technical Requirements for Testing Machines), GB/T 16491 (Electromechanical Universal Testing Machines), GB/T 12160 (Extensometers for Uniaxial Testing), and GB/T 16825 (Verification of Force Measuring Systems). It further supports execution and documentation in accordance with ASTM E4 (Load Cells), ASTM E8/E21 (Tension Tests of Metallic Materials), ISO 6892-1 (Metallic Materials – Tensile Testing), ISO 7500-1 (Static Calibration of Tensile/Compression Testing Machines), DIN 51221 (Testing Machines – Verification), JIS Z 2241 (Tensile Testing of Metals), and BS EN ISO 6892-1. Audit-ready data logging satisfies GLP/GMP traceability requirements, including timestamped operator ID, environmental condition capture (temperature/humidity), and full change history for calibration parameters.

Software & Data Management

The embedded measurement and control software provides ISO/IEC 17025-aligned data integrity: all raw channel data (load, displacement, extensometer signal) are acquired at ≥1 kHz sampling rate and stored losslessly in proprietary binary format with embedded metadata (test method, specimen ID, operator, date/time, environmental readings). Export options include CSV, XML, and PDF reports compliant with FDA 21 CFR Part 11 when deployed with optional electronic signature modules. The system supports audit trail functionality—recording every parameter modification, calibration event, and report revision—with immutable timestamps and user attribution. Batch testing mode enables unattended sequential execution of identical protocols across multiple specimens, with automatic pass/fail flagging against user-defined acceptance criteria. Data security includes role-based access control, encrypted local storage, and configurable backup intervals to network drives or external media.

Applications

Typical use cases span aerospace component qualification (e.g., aluminum alloy sheet tensile properties per AMS 4027), medical device validation (suture tensile strength per ISO 10993-12), electronics manufacturing (PCB flexural modulus per IPC-TM-650 2.4.1), packaging R&D (peel adhesion of laminated films per ASTM F904), wire & cable certification (conductor elongation per IEC 60228), and advanced material development (ceramic matrix composite interlaminar shear per ASTM D2344). Universities employ the system for undergraduate mechanics labs and graduate-level fracture mechanics studies. Quality assurance teams in automotive Tier-1 suppliers utilize it for incoming inspection of stamped steel parts and thermoplastic injection-molded housings. Its modular design allows future expansion with environmental chambers (-70°C to +300°C), video extensometry, or acoustic emission modules.

FAQ

What accuracy class options are available for the YRWT-M200?
The system is configurable as either Class 0.5 or Class 1 per GB/T 16491 and ISO 7500-1, validated through third-party calibration certificates traceable to NIM (National Institute of Metrology, China).
Does the system support ASTM and ISO standard test methods out-of-the-box?
Yes—the software includes preloaded test templates for ASTM E8, ASTM D638, ISO 6892-1, ISO 527-1, and ISO 178, with automated calculation of all required metrics and pass/fail assessment against specified tolerances.
Can the YRWT-M200 be integrated into an existing LIMS or MES environment?
It supports OPC UA and TCP/IP-based data export protocols, enabling bidirectional communication with laboratory information management systems (LIMS) and manufacturing execution systems (MES) for automated result ingestion and workflow synchronization.
What maintenance schedule is recommended for long-term accuracy retention?
Annual verification per GB/T 16825 is advised; quarterly functional checks of limit switches, emergency stop circuitry, and software diagnostics are included in the standard maintenance protocol.
Is remote technical support and software update capability available?
Yes—secure remote desktop access (with customer consent) and over-the-air firmware/software updates are supported via encrypted TLS channels, minimizing instrument downtime.
