Key Features

  • In extended range mode the maximum sensing range is 2 kilometers
  • The OBR 4600 for sensing has a dual display with an intuitive user interface that allows the user to simultaneously view a plot of temperature and strain in the upper graph and a magnification of sections of that plot in the lower graph
  • The user interface can store and display up to five traces (two traces in desk top analysis mode)
  • The scanning wavelength range, sensing range, gage length and sensor spacing are all user adjustable and offer the user maximum flexibility to tailor OBR 4600 measurements to the application requirements
  • The spot scan option is available with the sensing option, offering higher spatial resolution over a user selectable 80 meter section of the total sensing range
