Vibration Recorder UHA

Product outline

Vibration Recorder UHA can measure the vibrations on the railed vehicles to evaluate the rail road track conditions and to maintain the railed vehicles. Vibration data is recorded real-time, processing to a PC card and can be printed it out. Also, data is analyzed via specialized PC software .

Features

  • Acceleration data is measured by strain gage pick-up at 12 bit resolution.
  • Digital vibration data is recorded to the printed form as analogue data real-time.
  • Data over the threshold is shown via LCD on the device. Those data can be transferred to PC by USB cable or printed out.
  • Optional markings, kilometer-point and speed, is printed on the paper every 100m or 1km. It can also be typed by the remote-switch.
  • All measurement conditions setup like start-stop is operated by its keyboard.
  • Data of each time or distance is recorded to PC card. Data viewing and analysis is performed by analysis software.
