RM-1 Sensor

Wireless Track Geometry & Void Monitoring

The RM-1 Sensor is a rugged, wireless triaxial inclinometer designed for high-precision track geometry and void detection, forming a key component of Railmonitor’s TrackBed360 Series. Built for extreme conditions, it delivers continuous, accurate measurements with minimal maintenance—ideal for long-term infrastructure monitoring.

🛰️ Key Features

  • Triaxial Tilt Measurement (X, Y, Z)
    Configurable data intervals from every 30 seconds to 24 hours.

  • Dynamic Z-Direction Monitoring
    Captures rail deflection per train passage with 0.1 mm resolution.

  • Edge Computing Capabilities
    Built-in data processing enables local analysis before transmission, reducing latency and network load.

  • Long Battery Life
    Up to 10 years of operation (based on hourly transmission) with no external power source required.

  • Fully Wireless & Secure
    Encrypted data transmission via optional LoRaWAN gateway to Railmonitor’s Digital Service Platform.

  • Extreme Environment Resilience
    Operates reliably from –40 °C to +85 °C, with IP68 protection and high impact resistance (2000g).
