Comparison of COTS inertial sensors for getting marine elevator's platform tilt values

Knowing in advance the status of the marine elevator is very important for the maintenance because it is being operated at sea and there is no maintenance specialists on board. Recently, elevator controllers have various sensors to monitor status of operating elevator for the preventive maintenance. We have a project to design NMEA 2000 network-based controllers with various sensors. They must be operated during the voyage and should stop the elevator when it is tilted more than 10 degrees. In this project we have used the inner sensor to calculate the platform tilt values of the elevator. We have also compared the low-cost and high cost COTS sensors to provide the efficient solution for designing a marine elevator controller. By using the actual product bundled tools, the measurements of the angular rate are same at the smoothly swing and extremely swing cases.
