2 LEA_EN_INC Description _ The inclinometer system is used to monitor the movement of large land masses.the system consists of an inclinometer probe equipped with servo accelerometer sensors with MEMS technology, a metered cable of appropriate length with special cable reel, a readout unit and data storage. Other accessories: grooved tubes of different diameters and materials, dummy probe, suspension probe and selfcentering cable pulley. Applications _ This inclinometer system is used in particular for monitoring earth movements surrounding drilling or excavation areas (construction of underground galleries and large earthworks) Also used in: Landslides Road or rail embankments Dams Diaphragms Galleries Mining Various

3 with digital sensor > LEA_EN_INC Features and benefits _ The inclinometer system with MEMS technology accelerometer sensor provides: Good resolution and accuracy Excellent repeatability Strength and reliability Long system life Ease of use Immediate response Cable Signal/power, graduated every 50cm Further healthy characteristics due to: Fixed aluminum fasteners on the measuring cable in a stable manner for better and more correct and easier positioning of the probe in the borehole. Presence of an inertial biaxial servo inclinometer with accuracy of ± 2 mm per 25 m, protected by cylindrical stainless steel casing. Systems available for applications in vertical and horizontal columns (or inclined) Measurement principle _ Present on the market for a long time, the MEMS inclinometer system we offer enable very precise measurements of the ground, acquired in boreholes, which allow the monitoring of micro-displacements of the ground and of structures. This technology is ideal for use in the monitoring of landslides, stability of dams, embankments, excavations, retaining structures and buildings. The digital MEMS inclinometer utilizes wireless monitoring technology which represents an evolution of classical inclinometer systems. This system allows, in particular, the acquisition of high precision measurements in reduced time, with graphic real-time rendering. The use of an extremely thin and light connection cable to the probe, its weight, bulk and Kevlar reinforcement wire ensure durability and practicality. Connection of the probe to the handheld unit, operating in WINDOWS environment through bluetooth wireless connection, allows the acquisition of readings in the two axes (A and B) in order to obtain estimates of the movements in real time. Specific analysis and processing software allows rapid and effective management of measurements. Data are analyzed quickly on site.
