LS-G6-LAS-TIL90-MON
2-in-1 Wireless Laser Distance Meter and Tiltmeter

The Trimble LaserTilt90 serves as a versatile 2-in-1 device, functioning as both a laser distance meter and tiltmeter. The laser component measures relative distances to reference points, which can be natural surfaces or target foils, while the tiltmeter provides precise measurements of deviations from the vertical level, whether on the ground or within structures. This wireless sensor is specifically engineered to deliver robust data for monitoring inclinations, movements, and differential settlements of slopes or infrastructures.

The LaserTilt90 can be easily positioned along convergence cross-sections up to the excavation front, or until measured relative displacements stabilise when reducing the frequency of measurements. It’s also suitable for permanent monitoring, offering the capability to measure deformations in underground excavations and mining operations without causing disruptions or delays.

For data transmission, the LaserTilt90 utilises long-range radio technology to communicate with a gateway connected to the internet, reaching distances of up to 15km. A single gateway can manage multiple data loggers within the network, employing either a star or tree network topology based on the reporting period.

In terms of energy efficiency, the LaserTilt90 operates on autonomous battery power, using C-size batteries that can last up to 10 years with minimal to zero maintenance. It boasts an IP68 certification and operates reliably within temperature ranges from 0°C to 50°C.
