RET1000 – Integrated audio/acceleration measurement node for characterizing wheel-rail interaction

---

The RET1000 is a compact, energy-efficient acquisition unit for recording mechanical load data and noise during operation. The measurement node provides data for characterizing interfaces between vehicles and infrastructure (e.g., wheel-rail interaction).

• Multi-channel monitoring of noise and acceleration
  Records raw data from microphones and acceleration sensors with accurate time stamps, enabling the identification of more complex relationships in the wheel-rail context.
• Robust, minimalist design
  Consists only of a main unit with integrated antenna – easy to install and ideal for harsh environments.
• Mounting on the bogie
  Tested and qualified for use directly on the bogie under dynamic load.

• Power Supply: Battery-powered (low energy consumption)
• Mounting: Qualified for bogie-mounted use
• Connectivity: Internal data storage; external interface on request
• Components: Main unit + antenna
• Use Case Focus: Direction tracking, mechanical stress logging

• Load-Based Maintenance Planning
• Digital Twin Data Collection
• Directional Usage and Route Profiling
• Mechanical Stress Monitoring
• Fatigue Risk Identification
• Harsh Environment Deployment (e.g. bogie-mounted)

If you need a robust device for collecting raw data to measure mechanical stress or wheel-rail effects over short to medium-term measurements in operation, the RET1000 is the ideal solution.

For simpler systems for operational use with intelligent data preprocessing, we recommend RAILCTX and MOVCTX.
