Wi-SOS 480 LaserTilt 90

The Wi-SOS 480 LaserTilt 90 is a 2-in-1 laser distance meter and tilt meter. The laser measures the relative distance between pairs of reference points. One of the two points can be a natural surface or target foils while the node can be placed at the other end point. Meanwhile, the tilt meter provides measurements of changes from the vertical level, either on the ground or in structures and is used to monitor inclinations, movements and differential settlements of slopes or infrastructures.

The LaserTilt90 is capable of transmitting data via long-range radio to a gateway connected to the Internet. One gateway can support hundreds of edge devices in the same network. These edge devices are also measuring other sensors installed in the monitoring sections (borehole extensometers. pressure cells. load cells. strain gauges etc.). lt can be easily configured and connected with a USB cable and an Android phone. The device network can also be easily managed through the Connectivity Management Tool.

Measurement of tunnel convergence is one of the most important controls of the NATM (New Austrian Tunneling Method) construction. Portable devices like tape extensometers, levels and temporarily installed total stations allow sporadic measurements. One of the most commonly used methods, the measuring tape, disrupts construction activities due to the use of aerial work platforms.

The LaserTilt90 may be easily relocated along the convergence cross sections up to the excavation front or until the measured relative displacements are stabilised when the required frequency of measurements is reduced. lt can also be used when permanent monitoring is required. The wireless sensor can also measure deformations in underground excavations and mining without causing work disruptions and delays.
