TLO Train Speed Radar Sensor

Train Load Out Low Speed Radar – iTLO 4003 (RS485)


  • Multi-purposes sensor – detect distance, forward and reverse speeds
  • Slowest Motion Detection on the market: speeds ranges from 0.2 km/h and up to 45 km/h (High speed version iTLO4001,  0.8km/h – 250km/h is also available)
  • Distance range: 0.3 – 50m
  • Firmware upgradable
  • Advanced graphical user interface (GUI) for configuration and firmware upgrade.
  • High resolution speed outputs via RS485 and three PWM (Pulse Width Modulation)
  • Long distance multi-nodes communication via RS485
  • Industrial standard input voltages: 10 – 30 VDC
  • Built for industrial environment: IP67

Measuring train speed accurately in a train load out system is crucial for wagon loading weight control and automation. Traditional train speed cameras are not sufficiently accurate with accuracy often compromised by sensitivity to environmental factors such as light and dust. Calculating train speed from track switches is noisy, requiring use of a heavy filter compromising accuracy which is lost during changes of speed.

Accurate in all harsh environments

The iTLO 4003 Doppler Radar provides excellent accuracy and is designed to be robust in any industrial environment. It is designed for slow moving wagons in a train load out system or any applications requiring high resolution slow to medium range speed measurement or motion sensing, using specialised signal processing for accurate and reliable motion speed detection.

Field Proven

The iTLO4003 Doppler Radar has been tested successfully in mine sites of high profile mining companies.

 Low Cost

Compared to widely utilised traditional speed cameras, the iTLO4003 radar is only a fraction of the cost.

High update speed and resolution

Measurement update every 75 ms with 3 decimal points of accuracy resolution.
