- Measurements for the angular variation of tunnels, dams and road surface

  - Measurements for the angular variation of structures during construction or after completion of construction

  - Measurements for the angular variation of adjacent structures due to the construction of downtown

  - Safety evaluation on adjacent structures when works excavation and stacks the soil

  - Built-in FBG sensor for temperature compensation

  - ¡°USA, EU, China, Japan, Canada patents¡± registered

  - Effective cost saving

    : Compared with other companies of which FBG Tilt-meters are operated broad bandwidth in the range of wavelength 

     by using ¡°TWO FBG¡± sensors, our sensors can be operated at half of that because they use only ¡°ONE FBG¡± 

     for angle measurement and have high accuracy. Therefore Interrogator cost can be reduced.
