Track inspection data recorder

Track inspection data recorder

This is a data recorder for measuring train track conditions. Track deviation data collected by each sensor is digitized and recorded on a memory card along with location information. The recorded data is processed on a personal computer, allowing for the creation of many data analysis and documentation materials, such as track maintenance data, with little effort.

Features
  • Capable of recording 500 km of continuous measurement data (standard)
  • Capable of measuring at high speeds (140 km/h)*
  • Motion measurement is possible at the same time as track surveying
  • Support for inputting various types of location information
  • Compatible with rail seam detector

 

*Depends on conditions such as the number of input points, measurement distance interval, etc. Please contact us for details.

  • Specification
    Analog input

    Max. 15 points
    Orbital deviation, upset, wavy wear
    Reaction plate
    Digital Inputs 10 points (seam, reflector, ATS)
    A/D converter 16-bit
    Simultaneous sample hold at all points
    Display 6.4-inch color LCD with backlight
