Tilt monitoring on antenna base station
Applications
Location: Toulon, France
Site monitored since: March 2018
OVERALL TASKS
Toulon Naval Base is the second-largest naval port in France. Located on the south-east coast of the country, the base is he home port of the French Navy Mediterranean fleet.
Military antenna base stations and Radars are deployed on cliffs and covers communication with military ships. A soil subsidence of 0.05deg per year is provoked by water infiltration in the soil. A real-time monitoring system was required to monitor soil subsidence with a precise wireless inclinometer (factory precision of ±0.02° on the FS) and remotely sends alarms by email when the alarm threshold is reached
EQUIPMENT USED
BeanDevice® 2.4GHz HI-Inc | Wireless inclinometer sensor | tilt / inclination / slope monitoring | built-in datalogger
BeanDevice® 2.4GHz HI-Inc X-range | Wireless inclinometer sensor | tilt / inclination / slope monitoring | built-in datalogger | High-Performance version
RESULTS AND CONCLUSION
Since March 2018, 20 wireless inclinometers were deployed to monitor the inclination on 10 radars and antenna base station, with an accuracy of ±0.02° on the FS . Measurement drift is only 0.001° per year and the wireless system is showing a great stability over the time.
Caption 1: Installed under the antenna base station, our wireless inclinometer (Ref: BeanDevice® 2.4GHz HI-INC) is monitoring soil subsidence with an accuracy of ± 0.02°
Caption 2: For a better IP protection, the wireless inclinometer is integrated inside a waterproof casing.
Caption 3: Remote access is enabled thanks to our Wireless IOT Supervision sofware (BeanScape® 2.4GHz)
