The LaserTilt90 wireless sensor is a 2-in-1 laser rangefinder and inclinometer. The laser measures the relative distance between reference point pairs. One of the two points can be a natural surface or target leaves while the node can be placed at the other end. Meanwhile, the inclinometer provides measurements of changes from vertical level either on the ground or in structures and is used to monitor inclinations, movements and differential settlements of slopes or infrastructure. FEATURES Wireless sensor. An integrated unit (2-in-1 sensor + data logger). Accurate distance measurement through a visible Laser Class II laser with 655 nm. 3-axis inclination with respect to gravity’s direction and a range of ± 90° Long battery life (up to 8.5 years @6 h sampling rate). Long-range communications (up to 15 km/9 miles). High repeatability. Robust, small and weather-proof box. Easy configuration. APPLICATIONS Tunnel and mining convergence monitoring. Deformations in underground excavations. Remote monitoring of slope movements. Fracture and faults surveillance. Bearing and expansion joint movements. Monitoring displacement in structures and buildings. Bridge and structural health monitoring. Measurement of settlement at a single point
