The INTERFELS tradition has over the years been enchaced by innovations in the field of manufacturing geotechnical instrumentation and monitoring, data acquisition, software and technologies. In 1996 INTERFELS was aquired from BoartLongyear.

I NCLI NATI ON

IN C L I N AT I O NVERTICAL INCLINOMETER SYSTEM
APPLICATIONS
The Vertical Digital Bluetooth Inclinometer provides accurate profiles of lateral deflections in two perpendicular planes (i.e. biaxial). These include: • Embankments, landslide zones and retaining walls • Dams and slopes (natural or man made) • Bridge piers, abutments and landfills • Ground deformation due to tunnelling and excavation

HORIZONTALINCLINOMETER SYSTEM
APPLICATIONS
The Digital Bluetooth, Uniaxial Horizontal Inclinometer provides high resolution and accurate profiles of settlement or heave in geotechnical and civil engineering structures such as dams, embankments, bridge piers and abutments, storage tanks and landfill areas.
