The Loadsensing laser distance meter node 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. It can be used to measure changes in the
distance between walls, tunnel convergence, bearing and joint movements in bridges, lifting and placement of structures and
movements of historical buildings. It can also be used to monitor slope movements and for fracture and faults surveillance.
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. On the other
hand, one of the most commonly used methods, the measuring tape, disrupts construction activities due to the use of aerial work
Laser distance nodes can be easily relocated along the convergence cross sections up to the excavation front or until the measured
relative displacements are stabilized when the required frequency of measurements is reduced. It can also be used when permanent
monitoring is required.
In a similar way, the laser distance node measures deformations in underground excavations and mining without causing work
disruptions and delays. The Loadsensing laser distance node is an easy-to-use product that reduces costs and increases the quality and
availability of data in different applications.
The Loadsensing laser distance node is capable of measuring the relative distance and transmitting the data via long-range radio to a
gateway connected to the Internet. One gateway can support hundreds of Loadsensing nodes in the same network that are also
measuring other sensors installed in the monitoring sections (borehole extensometers, pressure cells, load cells, strain gauges etc.).
It can be easily configured and connected with a USB cable and an Android phone.
