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.

• 3 internal microphones with changeable membranes and internal heating
• Bus Connection for external acceleration / shock sensors and climate sensor
• 2 digital inputs and 2 relay outputs
• Positioning using internal GNSS/GPS module, separate GPS module on roof or offline without GPS
• Power Supply: Onboard power supply 24V/36V/48V/72-110V
• Mounting: Bogie mounting
• Connectivity: Internal data memory and cloud connectivity using internal dual SIM LTE
• Local Intelligence: Internal Quad Core CPU with possibility for intelligent realtime data analysis and local processing

• 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.
