W+B LFM/V Universal Testing Machine Modernization Retrofit Kit

Overview

The W+B LFM/V Universal Testing Machine Modernization Retrofit Kit is an engineered solution for extending the service life, measurement fidelity, and operational compliance of legacy universal testing systems—regardless of original drive architecture (hydraulic or electromechanical). Designed and validated in Switzerland, this retrofit platform replaces obsolete analog or proprietary control electronics with a synchronized digital control architecture centered on W+B’s high-resolution digital controller and the DION materials testing software suite. The system operates on standard industrial PCs running Windows OS, enabling deterministic real-time control loops with sub-millisecond sampling intervals, closed-loop PID regulation of load, displacement, and strain, and full traceability of test parameters per ISO/IEC 17025 requirements. Unlike piecemeal upgrades, the LFM/V retrofit constitutes a holistic re-architecture—not merely a controller swap—but includes recalibrated transducer interfaces, updated power supply conditioning, noise-immune signal conditioning modules, and firmware-level alignment with modern metrological standards.

Key Features

• Digital controller with dual-channel 24-bit ADC resolution for simultaneous load and displacement acquisition at up to 10 kHz sampling rate
• Modular hardware design supporting seamless integration with existing W+B or third-party frames (including MTS, Zwick, Instron-compatible mechanical structures)
• DION software platform compliant with FDA 21 CFR Part 11 for electronic records and signatures; includes audit trail logging, user role management, and electronic signature workflows
• Calibration certificate support for force sensors traceable to national metrology institutes (e.g., METAS, NIST, PTB) per ISO 376 and ISO 7500-1 Class 0.5 or better
• Real-time data streaming via TCP/IP to local networks or enterprise LIMS systems using standardized ASTM E1382-compliant data exchange protocols
• Optional high-speed video extensometry interface (via GigE Vision) for non-contact strain measurement synchronized with force-displacement data

Sample Compatibility & Compliance

The LFM/V retrofit maintains full compatibility with standardized specimen geometries defined in ASTM E8/E8M (tensile), ASTM E9 (compression), ASTM E21 (high-temperature tensile), and ISO 6892-1 (metallic materials). It supports both servo-hydraulic and electromechanical actuation platforms without requiring frame modification. All upgraded sensor channels are validated against ISO 7500-1 (static calibration) and ISO 13389 (dynamic performance verification). The system meets GLP and GMP documentation requirements through built-in test method templates, configurable reporting engines, and version-controlled procedure storage. Traceability is ensured via embedded digital calibration certificates linked directly to sensor serial numbers and certified by W+B’s accredited calibration laboratory (ISO/IEC 17025:2017 accredited).

Software & Data Management

DION software serves as the central analytical and operational interface, providing ISO 5893-compliant test sequencing, multi-step ramp-hold cycles, automatic yield point detection (0.2% offset, tangent, or maximum slope methods), and real-time statistical process monitoring (SPC) overlays. Data export options include CSV, XML (ASTM E1439), PDF reports with embedded digital signatures, and direct SQL database insertion for integration into QMS platforms such as TrackWise or MasterControl. All raw waveform data is stored in lossless binary format (.dionbin) with metadata headers containing environmental conditions, operator ID, calibration status, and instrument configuration snapshots—enabling full forensic reconstruction of any test event.

Applications

This modernization kit is deployed across aerospace component qualification labs (e.g., fatigue testing per ASTM E466), automotive Tier-1 supplier QC facilities performing weld joint characterization (ISO 14327), medical device manufacturers validating polymer suture tensile strength (ISO 13485-aligned workflows), and academic research centers conducting high-strain-rate deformation studies using split-Hopkinson bar synchronization. It is particularly suited for laboratories transitioning from paper-based GLP practices to fully auditable digital workflows while preserving capital investment in mechanically sound legacy frames.

FAQ

Can the LFM/V retrofit be applied to non-W+B frames?
Yes—the hardware abstraction layer supports mechanical integration with frames from Instron, ZwickRoell, Tinius Olsen, and MTS, provided mechanical mounting dimensions and actuator stroke limits are verified during pre-installation engineering review.
Is DION software validated for regulated environments?
Yes—DION holds documented IQ/OQ/PQ protocols aligned with GAMP5 guidelines and includes configurable 21 CFR Part 11 compliance modules with electronic signature enforcement and audit trail retention policies.
What is the typical lead time for a full retrofit installation?
Standard delivery is 12–16 weeks from order confirmation, including site survey, mechanical interface verification, factory calibration, and on-site commissioning with operator training and final SAT documentation.
Does the upgrade include recalibration of existing load cells?
Yes—W+B provides recalibration services traceable to METAS or equivalent NMIs, with new calibration certificates issued for all transducers integrated into the upgraded system.
Are firmware updates and software maintenance included post-installation?
A 12-month comprehensive support agreement is included, covering remote diagnostics, firmware patches, DION version upgrades, and priority technical response within 4 business hours for critical system faults.
