HFRR Tester FFT-M: Next-Generation Lubricity & Wear Evaluation

The Rtec Instruments FFT-M is a cutting-edge, benchtop High-Frequency Reciprocating Rig (HFRR) engineered to evaluate the lubricity of diesel fuels and screen the friction and wear performance of engine oils, greases, and additives. By moving away from traditional mechanical setups that rely on prone-to-wear dead weights, the FFT-M utilizes advanced programmable force control and a proprietary bearingless suspension to deliver unmatched testing precision and reliability.

As the authorized distributor for Rtec Instruments in Singapore, LMS Technologies Pte Ltd provides top-tier scientific instrumentation, localized technical support, compliance calibration, and application expertise for the region’s automotive, petrochemical, and fuel testing laboratories.

Key Functions & Innovative Features

  • Bearingless Flexure Design: The FFT-M utilizes a voice coil-based flexural suspension system that is entirely free of mechanical bearings. This design eliminates internal mechanism friction, ensuring ultra-high data purity and long-term reliability.
  • Closed-Loop Downforce Control: Replace antiquated dead weights with real-time electronic force control. Users can program constant, linear, or step force profiles dynamically during a single test run for superior repeatability.
  • Ultra-Precise Stroke Control: Achieve the industry’s most precise performance, with a controllable stroke range from 10 µm to 2.8 mm at frequencies up to 200 Hz. Real-time stroke and frequency monitoring is continuously managed via an integrated LVDT.
  • In-Line Piezo Friction Monitoring: Equipped with a high-frequency Piezo sensor to monitor and capture changing surface dynamics in real time with exceptional sensitivity.
  • Comprehensive Environmental Simulation: The integrated enclosure supports closed-loop control over humidity, temperature, and inert gas integration, allowing you to perfectly simulate specific real-world operating conditions.

Target Applications in Singapore

Our Rtec FFT-M solutions are tailored to support the specialized needs of Singapore’s fuel and materials sectors:
  • Petrochemical & Fuel Testing: Precisely determine the lubricity of diesel fuels to ensure compliance with strict commercial and environmental international specifications.
  • Lubricant & Additive Development: Rapidly screen and optimize the anti-wear and friction-reducing performance of new engine oils, industrial greases, and specialized additive formulations.
  • Academic & Industrial R&D: Investigate linear friction, fretting phenomena, and wear-track evolution on advanced material interfaces.

Strict Standards Compliance

The Rtec FFT-M HFRR tester is fully compliant with the major international testing standards required by global laboratories:
  • ISO 12156-1: Standard test method for assessing diesel fuel lubricity.
  • ASTM D6079 & ASTM D7688: Standard methods for evaluating diesel fuel lubricity.
  • CEC F-06-A-96: Established fluid lubricity evaluation protocols.
  • IP450 & BS-EN590 / BS-EC590: Compliance pipelines for European and international diesel quality specifications.
Note: The system is supplied with standard reference calibration oils (high and low viscosity) and standardized test disks to ensure seamless routine calibration verification.
