Bent inclination observation system

Real time monitoring of bent and piers tilt.
Detects the possibility of serious accident caused by collapse etc. in advance to prevent accidents.

Warning when the bent tilts more than the specified angle (Rotation warning light / Alarm mail).


  • Install tilt sensor on the vent and send tilt data (2 axis) to Cloud WEB server.
  • Connect to the cloud web server from the office via internet. The data can be viewed in real time on a personal computer .
  • The measurement range of the inclination sensor is ± 5 degrees.
  • Up to 10 observation stations can be observed simultaneously for each receiving station.(The number of observable stations that can be connected depends on the data update interval.)


  • On-site equipment consists only of integrated box with waterproof performance.
  • The device size is compact and easy to install, lower cost than conventional products.
  • Operates with AC100V power supply or solar panel(option).
  • At the office, data can be viewed on a personal computer. (Internet environment is required)

Data browsing

  • Special software installation is not required. Viewable on PC browser.
  • Measurement points, graph display, time axis can be changed (1 hour up to 1 month)
  • Graph display only for specified observation stations, time axis can be changed (1 hour up to 1 month)
  • Function of rotation warning light by threshold (option, three-step switchable)
  • Alarm mail transmission function (maximum 5 places)
  • Data offset correspondence after installation
  • Display data history
  • Data download (CSV format)

Radio specification



  • Sensor installation location must be horizontal.
  • Even in the case of a tilted bent, the measurement range is ± 5 degrees from the horizontal.
  • AC power supply is required for each observation station.
  • Since 920 MHz band radio is used for data transmission, there must be no equipment that emits radio waves in the vicinity.
  • There must be no obstacles between the observation station and the receiving station.
