This tilt meter can be directly fixed on a wall/structure. Option is also available to fix the tilt meter to a beam of length 1 m, 2 m, and 3 m and used as a beam sensor for monitoring of differential movement and rotation in structures. It is also used for monitoring deflection and deformation of retaining walls. This tiltmeter (box type) is with a SDI-12 digital interface such that all sensors can be connected through a single bus cable to a compact automatic data logger.
